terminatorX ChangeLog

   Copyright (C) 1999-2004 Alexander König

   Version 3.82
     * the position of the audio control scrollbars is now saved within
       set files and restored upon loading.
     * fixed a liblrdf related issue resulting in use of previously
       free'd memory.
     * rendered a new knob with the wonderful povray - all images are now
       distrbuted in gdk-pixbuf-csource'd form in the src/icons
       directory.
     * added an extra "File/Load Audio File" menu item as new users would
       always try to load an audio file via "File/Open".
     * fixed compilation issues with g++ >= 3.4.
     * added reverse mapping of MIDI parameters which can be turned
       on/off via the parameter menu. This allows setting up a MIDI
       controller as a crossfader.
     * in order to have a SPAM protected online version of the ChangeLog
       this document is now generated from XML sources.
     * merged a patch from Martin Habets
       <errandir_news@mph.eclipse.co.uk> that fixes big endian audio
       playback with ALSA.
     * applied a fix from Juha Erkkila <erkkila@cc.jyu.fi> that makes tX
       work on systems that don't have procfs mounted.
     * added an optional Dry/Wet control for all LADSPA plugins. Simply
       click on the plugin's label to add or remove the additional
       control.
     * added an additional stereo effects queue that allows loading
       stereo LADPSA plugins. The stereo effects are located below the
       mono effects - to add a new instance press the "Stereo FX" button
       and select the plugin of your choice.
     * fixed the plugin menu - empty categories no longer get a menu
       entry
     * plugins that do not qualify as realtime capable will now be
       disabled.
     * I'm fed up with terminatorX related security postings, so the old
       suid-root method had to go. To achieve realtime scheduling you now
       have three options:
          + a) run terminatorX as root (obviously dangerous and not
            recommended)
          + b) build terminatorX with capabilities enabled and install it
            suid-root. Due to the use of PR_SET_KEEPCAPS this will work
            on Linux _only_
          + c) use the JACK backend with "POSIX draft capabilities" (see
            jackd manpage)
     * loading sets with missing LADPSA plugins no longer crash tX.
     * fixed a bug that made reading error messages impossible with the
       load dialog open.
     * the engine now handles audiodevices that break down when already
       in playback mode more gracefully. This really necessary when jack
       decides to kick us out.
     * all vu meters are stereo now. Having a mono widget for a stereo
       thing just didn't make any sense anymore.
     * modified the render loop to comply with LADSPA V1.1: 0 db is now
       at 1.0f. This makes a lot of plugins work with terminatorX that
       haven't worked with previous releases.
     * data send to the JACK backend no goes through the
       "Anti-Clip-Device", too. Unless you #define TX_DO_CLIP of course.
     * I've drawn some new icons with the cool inkscape. They're now
       being built into terminatorX as gdk-pixbuf c-source code, so they
       actually do alpha blending.
     * wrote support for gtk+'s new FileChooser widget - will be enabled
       automatically when configure finds a gtk+ >= 2.4.0
     * fixed the buffer overflows detected by c0wboy <c0wboy@tiscali.it>
       in his outsiders-terminatorX-001.txt advisory.
     * support for gtk+ startup notification.
     * "README.GNOME" was outdated so it had to go.
     * merged parts of a patch graciously contributed by Adam King
       <aking@lgh.com.au>
          + simpler min/maximization for the control panels
          + bugfix for sequencer menu crash
          + the panel formally known as "Trigger" is now known as
            "Playback">
     * added cpu-overload detection - currently disabled

   Version 3.81
     * JACK doesn't seem to like SCHED_FIFO clients so I added a little
       test that will set SCHED_OTHER when jack output was selected. This
       will work for true root or a capabilities-enabled suid-root binary
       only.
     * removed the disfunctional "Cancel" button from the load-progress
       dialog.
     * switched default MIDI mapping to non-destructive. (previous
       settings will not be overwritten now).
     * added a default MIDI mapping accessible via the "Turntables" menu.
       The actual mapping is documented in the manual.
     * fixed a bug that caused enabling sync-client setting via MIDI to
       fail.
     * when compiled with rt-scheduling suppport terminatorX will now
       display the resulting scheduling policy in the "About" dialog.
     * if terminatorX was setup to use realtime priority for the audio
       engine thread but you dont want it - disable realtime scheduling
       in the Preferences dialog. This works with capabilities _ONLY_.
     * if you don't want to confirm program termination every time you
       can now disable "Ask for Quit confirmation" in the Preferences.
     * added support for Linux' POSIX capabilities. This allows a
       suid-root installed terminatorX binary to drop root privileges
       much earlier than with the old approach (so it should be more
       secure). Requires the libcap library.
     * obligatory documentation updates - clicking on the sub-sections
       should now work.
     * removed gtk+ 1.2 cruft - terminatorX now compiles with gtk+ 2.2
       and *_DISABLE_DEPRECATED macros enabled. To verfiy that you can
       run configure with --disable-deprecated.
     * terminatorX now has a JACK backend. Currently it works like this:
       on startup tX will connect to the JACK daemon - if the daemon is
       not available on startup JACK output is not available. When the
       audio engine is turned off, tX emits silence via the JACK ports,
       so you can leave the ports connected.
     * sick of green - you can now configure the colors terminatorX
       should use for the audio display as well as the vu meters in the
       Preferences dialog.
     * hopefully fixed wrong setting of the master volume when loading
       set files.
     * some ALSA installations seem to core on snd_pcm_hw_params_free()
       after sound device init. So freeing the hw_params can now be
       explicitly disabled in the Preferences - if terminatorX crashes
       right after hitting the "Power On" button it might be necessary to
       activate this for your ALSA setup. This probably results in a tiny
       memory leak - but on leak vs core you might decide for leak. Note:
       I even enabled the leak by default now.
     * fixed a bug that caused turntable 1 to get the focus on entering
       Mouse Grab mode even when it's audio panel was minimized.
     * MIDI mappings can now have "bounds", meaning that the incoming
       MIDI signals can modify the parameter within the given range only.
     * introduced a new way of assigning MIDI controllers to parameters:
       simply right-click on a parameter's control: a menu with "MIDI
       Learn" and "Remove MIDI Binding" will pop up - select "MIDI Learn"
       and send the corresponding MIDI event.
     * fixed a bug in the MIDI callback thanks to David Hamilton
       <daham2@student.monash.edu>
     * running suid root (the old way) was reported exploitable by Andrew
       Griffiths <andrewg@felinemenace.org> - the described environment
       variable based exploit was fixed - however there are possibly
       other ways to exploit it. So the old method of running suid root
       has been disabled by default. On Linux systems you really should
       use the capabilities based approach (see above). If really want to
       use the old suid-root solution run configure with
       --enable-suidroot.
     * often, you record events and mess things up - in this case I'd
       often prefer dropping the complete take instead of recording a bad
       perfomance - which is why you now can activate "Confirm Recorded
       Events" from the "Sequencer" menu. When enabled terminatorX will
       ask whether to actually record or drop the events created for the
       last take. The setting for this flag is stored in your
       ~/.terminatorXrc.
     * introduced a new "Sequencer" menu that allows to delete events of
       a specific type (all, all for certain turntable, all for a certain
       parameter) from the sequencer. Events can be deleted for the
       complete song, upto the current song position or from the current
       song position. Yeah, I know, termintorX is lacking a proper
       event-editor here, so where's your patch? ;)
     * switching the X11 mouse cursor when the user has to wait for
       terminatorX to finish some operation
     * fixed a sequencer bug: the events for master pitch and volume
       weren't erased correctly when another set was loaded
     * fixed FreeBSD issues with the configure script
     * fixed compilation issues for gcc 2.95.x

   Version 3.80
     * I've invested quite some time in valgrinding this release, among
       other things a major mem leak showed up - the sample memory wasn't
       being free'd correctly which is now corrected along with many
       other things. valgrind is a very helpful tool indeed.
     * Added a new Pitch Calculator that allows adjusting a turntable's
       pitch to that of the master turntable. This makes synchronizing
       finely cut loop samples really easy
     * XML based set files can get rather huge when they contain a lot of
       sequencer events - to solve this terminatorX now uses zlib to save
       compressed set files if enabled in the preferences dialog.
     * I hacked support for Steve Harris' cool liblrdf - if you've got
       that library setup correctly and you use Steve's wonderful plugin
       collection with RDF description you should get a nicely structured
       menu when clicking on the "FX" button. All plugins not categorized
       through RDF files go to the "Unclassified" category.
     * I'm no longer including the html and ps versions of the manual -
       it's now attached in it's XML/DocBook source and will be installed
       via scrollkeeper. terminatorX offers a menu entry to start
       gnome-help to display the manual.
     * Reworked the Preferences dialog - I now use glade-2 to create that
       code - I'm fed up with copy'n'pasting gtk+ code so now I'll let
       glade-2 do this whereever possible. The glade project files are
       included with this tarball in case you want to mess with them.
     * Switched to a fixed blocksize (1 ms) for rendering. This finally
       allows to playback set files with events recorded on machines with
       small buffer sizes on slow machines with large buffer sizes. The
       buffersize of the audiodevice has no effect on the "operating"
       blocksize anymore. Note that the samlping rate has a - very small
       - effect though. Depending on the sampling rate terminatorX will
       try to find a blocksize that fits exactly 1 ms - while this is
       easy for "straight" sampling rates (22000 32000 48000) this
       results in "44.1" samples for 44100 Hz.
     * Finally hacked a native ALSA backend. It's in "Works For Me" TM
       state.
     * Added "Remove Binding" button
     * MIDI now uses a GIOCallback so the effect of MIDI controllers is
       visible even without the audio engine turned on.
     * Reworked the mastergui for better usabilty and less space
       consumption, yes, terminatorX now features a boring menubar -
       which helps using it on small displays quite a bit, and should be
       easier to handle for first-time users.
     * Implemented a suggestion from Darrick Servis
       <darrick@dcn.davis.ca.us> that stops clipping in the mixer
       routine. The outgoing signal is now limited as it should be, which
       improves the output quality for signals too loud significantly.
     * MIDI mappings are now stored within the (new) tX set files.
     * Applied a patch from Arthur Peters <amp@singingwizard.org> which
       brings preliminary MIDI support to terminatorX. This is realized
       via the ALSA sequencer interface, so in order for it to compile
       you have to have the ALSA devel packages installed. ./configure
       will autodetect them.
     * Fixed a bug in XML serialization that dropped strings' contents.
     * You can now hit "F11" to turn fullscreen mode on/off - this will
       help using terminatorX on small DJ laptops. Note that the key will
       have no effect in scratch mode - hit it before you enter grab
       mode. This feature requires a NETWM compliant window manager.
     * terminatorX now stores set files as XML documents, too - so
       terminatorX has become terminatorXML finally. Note: for sets with
       a large number of events recorded into the sequencer - the XML
       based set files can grow significally larger than the old ones
       (see "compression" above)
     * The old code to support the obsolete binary tX file formats has
       now been scheduled for deletion. It's been moved into the
       tX_legacy* source files and it will be built only when
       "--enable-legacy" was used on configuring terminatorX (which is
       the default). Expect this to become disabled and then totally
       removed from the sources in future.
     * Enhanced audio data display - you can now zoom into the audio
       signal, which should allow much more precise scratching with
       larger audio files (ie complete tracks). On playback terminatorX
       will scroll the displayed area to ensure you always see the area
       of the sample in which you're currently scratching on.
     * I have not backported the new code to the old gtk+ 1.2 - so this
       release no longer builds with gtk+ 1.2 - you have to upgrade to
       gtk+ Version 2 to be able to build terminatorX.
     * fixed a nasty gcc 3.2 compilation bug - thanks to Adam Duck
       <duck@informatik.uni-frankfurt.de> and other reporters

   Version 3.73
     * Fixed a compilation bug ocurring on big endian systems only.
     * Fixed the built-in wav loading routines for big endian systems
       (again).
     * Finally traced down and fixed a long outstanding bug in the dial
       widget, the background of the dials is now drawn correctly.
     * Ported terminatorX to gtk+ Version 2. The code for gtk2 will be
       enabled when gtk2 is detected by configure. To force terminatorX
       to use the good old gtk 1.2.x (x>=5) run configure with the
       '--disable-gtk2' switch. WARNING: gdkxft-users: gtk2 applications
       segfault when preloading libgdk_xft.so! So unset LD_PRELOAD and
       set GDK_USE_XFT=1 instead.
     * Applied a patch from Adrian that brings lots of new stuff:
          + Debian package support (removed - Mike Furr now maintains an
            official Debain package for terminatorX)
          + enhanced GNOME integration
          + a manpage for terminatorX
     * Included another gcc3 fix thanks to Gregor Riepl
       <seto-kun@freesurf.ch>>
     * Improved configure's compatibilty - it should detect pthreads more
       reliably and it should detect ladspa.h when located in
       /usr/local/include without /usr/local/include being contained in
       the include path.
     * This release should compile and run on FreeBSD systems and
       possibly OpenBSD, too. Thanks for help and testing this goes to
       Tilman Linneweh <tilman@arved.de> .
     * Sequencer now refuses to play when no events available - and
       displays a dialog that suggests running the audio engine.
     * De-uglified the terminatorX note dialog.
     * Fixed gtk+2 signals for load file dialog
     * Pre-listen support for mpg321
     * Added a new auto-hiding "panel-bar" to which turntable control and
       audio panels can be minimized to.
     * Cleaned up the turntables' audio panel for better looks and easier
       usage
     * Rewrote the engine thread completely - unlike before the engine
       thread is created on startup and kept alive until termination.
     * terminatorX can now be run suid root - and it might even be safe.
       After creating the engine thread both terminatorX threads drop
       root privileges before evaluating any parameters or
       reading/writing files, etc. The problem is the pthread "manager
       thread" is out of control of terminatorX code - so I cannot tell
       that thread to drop privileges.
     * Fixed Drag'n'Drop for GNOME 2
     * To enhance the loading of audiofiles terminatorX now contains code
       to use mad (MPEG Audio Decoder), libvorbis and libaudiofile
       directly instead of pipeing audio data through mpg123, ogg123 or
       sox. As a result the new routines bring following advantages:
          + tX loads audiofiles significantly faster
          + tX now honours the samplerate of an audiofile (by adjusting
            the pitch of the turntable)
          + tX provides much better feedback on the loading progress
       Although the old loading-methods are still available (and piped
       loading has been improved, too) I highly recommend installing the
       libraries above as the new routines simply work better.
     * Deleted tons of old outdated code in tX_engine.cc and
       tX_mastergui.cc

   Version 3.72
     * Applied a patch from Matthew Evans <activesx@hotmail.com> that
       introduces support for Ogg Vorbis audiofiles. It requires ogg123 >
       RC2 and sox to work. Autodetection is supported via configure
       (--enable-ogg123).
     * Experimental support for input devices other than the core-pointer
       under XFree86 > 4. This uses the xsetpointer executable that comes
       with XFree86. configure should autodetect this correctly, in case
       it doesn't use the --enable-xetpointer switch.
     * Adrian sent me a patch introducing two new buttons: mute and solo.
       As it didn't fully harmonize with the sequencer I rewrote parts of
       it and added new functionality to the turntables: They can now be
       switched to mix_solo or mix_mute - these settings affect current
       mixing only - their values will neither be saved nor will changes
       to those control be recorded in the sequencer - if you want to
       record muting events either use the mute button from the
       turntable's trigger menu, the keyboard short-cuts (alt/strg), or
       your middle mouse button.
     * fixed a bug that produced corrupt wavfiles on big endian machines
     * some minor fixes to make terminatorX compile with newer gcc
       releases
     * Well, I am allowed to change my mind, aren't I? Anyway, 3DNow! is
       back. Nevertheless newer gcc releases seem to have a bug in
       handling movq and the current 3DNow! stereo implementation does
       not seem to be very efficient. So use --enable-3dnow only if you
       want to help me improve perfomance.
     * Modified the mpg123 loader in order to make it work with mpg321,
       too. mpg321 lacks support for mpg123's -m switch ("singlemix")
       therefor mpg?2?'s output is now piped into sox to convert the
       signal to mono. For this reason mpg?2? support now requires sox to
       be installed, too.
     * added a workaround for a gtk+ bug that causes empty labels when
       strings contain umlauts - unluckily my name features one of these
       so I had to write this workaround.

   Version 3.71
     * applied a big patch from Adrian Reber <adrian@lisas.de> . This
       patch includes:
          + compile fixes for the newer gcc releases
          + enhancements to the commandline switches (try --help for more
            details)
     * the bigNewThang (TM) is STEREO output. The Pan-Buttons now
       actually do what you'd expect them to. Therefore your soundcard
       must have stereo support of course but I guess in 2001 this really
       shouldn't be a problem, right? The recorded wavfiles will now be
       stereo wavfiles of course. Note that stereo output means double
       audio-bandwith, so if you tuned your old terminatorX setup to
       smallest latency you might get clicks now. You can easily fix this
       by increasing the buffer size in the options dialog by one - this
       will result in the same latency as before btw.
     * The echo effect has undergone some enhancements to profit from the
       new stereo output. It's signal will now be mixed seperately so you
       can choose a different stereo panorama position for the echo
       signal. So the new echo effect now features it's own PAN-knob.
       This does have some sideeffects though, for more details on this
       check the manual. Additionally the echo effect now has it's own
       volume setting to influence the dry/wet ratio of this effect.
     * Some LADSPA effects tend to create NAN (Not A Number) float values
       under certain conditions. This is bad as all following operations
       will result in NANs, so there will be no audio output no more. Now
       I will not introduce code to check for NANs as this is a waste of
       CPU-power, producing NANs is IMHO a faulty behaviour for LADSPA
       plugins and it should be fixed in there. Now a problem with the
       previous release was that the echo and lowpass effects "ate" those
       NANs resulting in NANs in those effects' buffers. So once a NAN
       got in there these effects caused the whole audio output to mute
       (forever). Which is why I now introduced some code to clear the
       buffers in echo and lowpass whenever you dis- and reenable them.
     * The GUI does have two master vu-meters now. The turntable's still
       have one vu-meter only. Note that the echo-signal is *not*
       included in the turntable's vu-meter now, as it's mixed
       seperately.
     * The 3DNow!-Optimizations are gone. And they'll proabably never
       come back as I don't have time to maintain the same algorithm
       twice.
     * The documentation has been updated to meet the new features. A lot
       of typos have been fixed as well.

   Version 3.70
     * this list may be incomplete
     * This release brings support for LADSPA plugins. These plugins can
       be inserted into any turntable's effect chain at any position. You
       can edit the the effect sequence with the two tiny blue arrows.
       The builtin effects reside in the same effect chain as LADSPA
       plugins, but unlike LADSPA plugins they cannot be removed (nor
       multi-instanciated). The LADSPA plugins have to "fit" into the
       effect chain, which is why terminatorX supports *mono* plugins
       (plugins that have one audio-in and one audio-out port) only. For
       the plugin's control ports, termintatorX supports all HINTS except
       for LADSPA_HINT_LOGARITHMIC. Some control ports might be hard to
       handle as LAPDSA control ports can have very wide value ranges. It
       is possible to enter precise values though. Get LADSPA and the CMT
       plugins from http://www.ladspa.org. All parameters for
       LADSPA-plugins are "sequencable parameters", so you can record
       parameter-change events for the plugin's knobs just as for the
       standard parameters.
     * GUI re-design to support dynamic plugin GUIs. The
       audiofile-display is now seperated from the turntable's controls.
       The groups are split in to panels which can be minimized if not
       required (orange arrow). The panels' minimized-status will be
       saved within the set files. To add a plugin effect into the
       turntables effect chain click on the "FX"- button and choose the
       plugin of your choice. To get more info on the plugin effects
       click on their panel's label. NOTE: The panning-control is not
       working yet. It'll work as soon as stereo is done.
     * As always when introducing something new, the set-file file-format
       has changed.
     * The parameter-to-mouse-axis mapping has been moved from hardcoded
       to dynamic. You can now map any parameter that's considered
       "mappable" to the mouse-axis of your choice (for each turntable
       separately). This is true for the control ports of LADSPA-plugins,
       too.
     * Josh Steiner <joschi@eds.org> has joined terminatorX development.
       For this release he has added some startup parameters for
       terminatorX, some of them aiming for future MIDI support, and
       therefor not functional yet. Run "terminatorX --help" to get more
       details.
     * I know write the "manual" in SGML with the DocBook DTD. The
       distribution contains the HTML and the postscript version. These
       transformation have been created using James Clark's jade
       (DSSSL-processor) and Norman Walsh's DSSSL stylesheets for
       DocBook.
     * Removed obsolete "number of vtts"-option from the options dialog.
     * Applied a patch from Josh that fixes running the soundfile editor
       for files including a blank in their filename.
     * New tooltips for the complete GUI.

   Version 3.61 (unreleased) 
     * applied a tiny patch from Atsushi Yamagata
       <yamagata@plathome.co.jp> to set locale on startup.

   Version 3.60
     * terminatorX has a sequencer now. Warning: with the current design
       the sequencer will correctly play back recorded events only when
       the buffer size (of the audio device) is set to the same size as
       it was when recording the events. I know this is annoying and I
       will try to find a solution to this. Please take a look at the
       README to find out how the sequencer works.
     * fixed a bug causing the lowpass filter produce a constant signal
     * fixed the load file / drag'n'drop segfault bug
     * fixed the prelisten zombie processes bug
     * fixed the segfault on termination bug (with the audio engine
       running)
     * hacked the mixer code to use 3DNow! too. This improves 3DNow!
       performance gain from previously ~6% to more than 20% (depending
       on compiler optimizations)
     * extended the set-file-format to allow storing of sequencer events.
       This release allows loading old tX-sets too.
     * some gui icons. Choose Text/Icon / Icon only / Text only display
       of these icons in the Options dialog. You'll have to restart tX to
       see the changes though.
     * "soundfile-editor support": Enter the soundfile-editor of your
       choice in the tX-Options dialog (Still looking for an editor?
       Checkout Dave's Linux Sound and MIDI Pages:
       http://www.bright.net/~dlphilp/linuxsound/). Click the edit button
       in the Main-Panel to start your editor with the turntable's
       soundfile - edit ;) - save and click the reload button.
     * big endian bug fixes by Scott C. Knight <scknight@indiana.edu>
     * --enable-benchmark will now produce a benchmark binary. This takes
       a set file as a parameter (that set file should autotrigger all
       tables, else the benchmark will measure how fast tX can generate
       zeros ;) WARNING: the benchmark binary is not a usable terminatorX
       binary.
     * a new dial-widget. I created this for the upcoming GUI-redesign -
       and decided I let you debug it right now ;) If you don't want it
       run configure with the --disable-dial switch.
     * some gui redesign. The volume scales are now located near their
       corresponding "flash"-widget. This release fits into very small
       windows - so it should be usable on smaller displays as well.
     * Adrian told me configure doesn't have to check for glib after
       checking for gtk+ - I guess he's right so the glib-test has gone.
     * more minor fixes

   Version 3.55
     * implemented "sequenceable parameters" (see tX_seqpar.*). This
       means the groundwork for the sequencer is done. Although this
       release does not yet feature a sequencer - there's still a profit:
       you can now see the GUI (e.g. the lowpass-freq slider) update
       while you change that value with your mouse in dga grab mode (e.g.
       up/down with the default X/Y-Control settings).
     * fixed (libmmx) mmx.h to work with gcc 2.95 and above
     * fixed compilation problems for big endian machines. still runtime
       probs reported though.
     * fixed configure-script as the new bash complains about == in
       string compares
     * fixed some gui segfaults
     * added an ugly GNOME-mimetype installer. This installs the
       ".tX"-mime type, an terminatorX-application icon and a ".tX"-icon.
       I could use some hints on how I could make automake install that
       instead of an extra script. (see README.GNOME)
     * added Drag'n Drop support. Works with the great gmc. Drop an audio
       file over the filename-button or the wavdisplay of a turntable to
       load it into that table. Drop an audiofile over the "Add
       Turntable" Button to create a new turntable and load that file
       into that turntable. Drop a tX-set file over the "Load Set" button
       to load the set.

   Version 3.51
     * fixes the load_piped() compilation error if you use neither sox
       nor mpg123. Note that you have no "pre-listening" without mpg123
       for mp3s and no "pre-listening" for any other file without sox.

   Version 3.5
     * Yet another redesign ;) Oh well this project moved from
       c++/multithreaded to c++/singlethreaded, to c/multithreaded and
       now, finally, back to c++/multithreaded. This shows quite some
       foresight, I'd say ;)
     * Due to the redesign I had to change a lot (everything?) again so
       this document can impossibly hold all changes. but let's see:
     * tX now uses floats instead of doubles for a lot of parameters.
       Therefore the old .terminatorXrc.bin is now called
       .terminatorX3rc.bin to allow parallel use of older releases. But
       you'll have to configure the new release again the first time you
       run it.
     * tX now supports an unlimited no of turntables. The only limit is
       your display really.
     * Each of these turntables has their own pitch / volume settings and
       a dedicated lowpass and echo effect section.
     * You can now map mouse motion to a function of your choice
       (scratching/ volume/cutoff/echo-feedback and nothing)
     * Recording will now happen straight to disk. You'll have to specify
       a filename before you start recording.
     * You can sync the turntables to one master turntable.
     * There are two master settings for pitch and volume available to
       modify all turntables. The turntable pitch is relative to the
       master pitch.
     * You can save a complete set (of turntables and settings) to a .tX
       set file. The audiofile data will *not* be saved within that file,
       but it'll contain the absolut filename to these files. I know this
       makes the act of exchanging sets over the net more complex so if
       somebody wants to code set files with integrated audio data... ;)
     * The way audiofiles are loaded has been redesigned too: the builtin
       wav routines, the sox support and mpg123 are no longer connected.
       This means you can use mpg123 support without sox support and
       still have the builtin wav routines enabled. If you have the
       builtin wav reader and sox enabled, tX will try try to use the
       builtin routines first, and if they fail sox will be used as a
       fallback which is of course slower as you know... There's some
       support for Benno Senoner's brilliant 3.2-mmap() patch but the
       patch still needs to be ported.
     * You can now select which parameter to map to a mouse axis.
     * experimental 3DNow! support (works with gcc < 2.95 only)
     * tX-windows now have an icon, thanks Michael!

   Version 3.2
     * implemented 2D-Scratching ;) You can now use the other axis of
       your mouse two modify the cutoff frequency of the lowpass filter
       (if enabled). The resonance factor can be set via the slider
       underneath "LP Filter". Seems to eat quite some CPU power
       though...
     * Updated THANKS, AUTHORS
     * as most people seem to use sox/mpg123 anyway and as I still get "I
       want mp3" emails I changed the configure script slightly: It now
       automatically enables the use of sox and mpg123 if these are
       available. If you still want 'em good old 16Bit/44.1Khz/Mono
       builtin routines you have to specify --enable-wavonly with your
       configure cmdline.
     * Prepared the tarball for the Win32 port. You can now compile tX
       with cygwin and the Makefile.cygwin in the src directory if you
       have all the required libs (gtk, pthreads etc...). The resulting
       exe will run BUT is completely unusable for now... Stou Sandalski
       <tangui@cell2000.net> and I are planning to make it usable in the
       future.
     * The About-Dialog now contains some info on how the binary was
       compiled

   Version 3.1
     * Optimized audio-rendering code for speed (might run on some
       machines with smaller buffsize (-> lower latency) than pre-3.1) -
       Hey, tX now uses less than 10% CPU (says kpm) with mixing enabled
       on my i586-200MMX machine!!
     * "fixed" stdout-output. Due to the pipe-buffering realtime
       schratching can not be considered usable for now :(
     * Added config option --enable-scheduler, which will cause the
       terminatorX engine-thread to run with FIFO scheduling policy and
       highest priority. This might enable some machines to use smaller
       buffsizes. It requries root privileges though - either run
       terminatorX as root - or make terminatorX suid root WHICH IS A BAD
       IDEA FOR MULTI-USER SYSTEMS IF OTHER USERS CAN ACCESS THE BINARY
       ;) You only have to think about this when you experience buffer
       underruns with your desired latency. And it might not even help...
     * Rehacked the de-clicking (fading) code. The old one tried to be
       much more intelligent - and failed fading out the signal
       sometimes. The new code is much simpler (faster) and is much more
       reliable.
     * added common sense to the warp feature (f-key in scratch mode).
       The warping speed is still connected to the mouse speed but it's
       now adjusted to the sample size as well: you can warp through any
       sample completely with the same mouse distance.
     * added debug configure switch. Enables (very few) debug messages
       for now. I decided not to enable the old V2.X messages as they are
       sent to stdout, which would sound pretty strange to people who use
       the stdout-option.

   Version 3.02
     * Fixed Adrian's name in the THANKS file. Sorry, Adrian.
     * Corrected Makefile.am for license.c that did not build correctly
       on some systems - Thanks to Michael Pruett
       <mikep@ugcs.caltech.edu>

   Version 3.01
     * fixed a bug that caused terminatorX to crash without --enable-sox
       or mpg123input.

   Version 3.0
     * Changed everything ;)
     * switched from C++ to C for gtk's sake
     * switched back two multithreading
     * implemented new gtk+ gui and dialogs
     * new mouse-sampling code now uses DGA's DirectMouse
     * implemented "initalizing"-support for XInput devices.
     * new (alpha) "pre-listening" feature in scratch/loop dialogs
     * hacked vtt for click-free audio. Might be problematic with big
       kernel level buffersizes but scratching with big buffsize is no
       fun anyway.
     * options are now stored in ~/.terminatorXrc.bin automatically (on
       exit) as well as windowsize and the last used filenames
     * terminatorX now comes with a configure script - no more Makefile
       hacking required (nor a good idea ;) )
     * new wavdisplay-widget update frequency is now configureable
     * new position-display is much more visible which allows more
       precise scratching
     * new mute-feature allows you to silence the scratch-playback
       completely while the loop keeps playing (press either <m>-key or
       right mouse-button.
     * support for mouse buttons:
          + 1. (left) button: same as <SPACE>, do scratch
          + 2. (right) button: mute scratch
          + 3. (middle) button: stop
     * wrote support for sox and mpg123. This enables terminatorX to read
       close to any audiofile. You need to have sox and mp3 and this
       feature (as it is still alpha) needs to be enabled via
       configure-switches see INSTALL
     * licmak now is an awk script. Thanks Christian! I was also received
       two perl scripts (Thanks, guys!) but I now use the awk script as
       it is the smallest.
     * introduced <F>-key to "warp" through scratch-sample (just check it
       out)
     * dropped commandline arguments
     * dropped old X-Code + Mouse warping madness
     * bug fixes (less than bug introduces though ;) )

   Version 2.4 (unreleased) 
     * implemented a time counter
     * licmak now finally is what it should be: a perl script (licmak.pl)
       it was contributed by Adam Sjøgren <asjo@diku.dk> . Thanks!

   Version 2.3
     * wavfile overreading fixed by Andrew C. Bul+hac?k <acb@zikzak.net>
     * Using portable type definitions now where required. If you don't
       have a <sys/types.h> on your system and your machines type sizes
       equal those of an X86-machine you can specify -DUSE_X86_TYPES in
       Makefile to compile without <sys/types.h>
     * Slight change in audiodevice-handling that fixes improper buffsize
       settings on some soundcards (e.g. GUS)
     * Implemented "keep device open"-feature. Needs to be enabled via
       the -DKEEP_DEV_OPEN switch in Makefile
     * Added some comments to the Makefile for easier editing
     * Added Big Endian support. Use -DBIG_ENDIAN_MACHINE for big endian
       hosts like ultrapenguin suns or linux ppc. There's also
       -DBIG_ENDIAN_AUDIO for big endian audio hardware (rare?)
       available, although proabably nobody will need this.
     * Changed mix behaviour: Mix is now automatically turned on on
       startup if the user has specified a proper loop file. (with the
       --loop or -l switch)
     * New mixing routine. You can now set the loop to scratch volume
       ratio with the cursor keys (left/right). If you modify the volumes
       while recording these action's will not be recorded. Saving
       happens with the currently set level.
     * Fixed README-Bug said <m> instead of <x>

   Version 2.2
     * first released version
     * added colors, more standard use of X11
     * added loop support
     * added statusbar with mode/status display
     * added commandline options and help (on usage and keys)
     * added raw/mixed save scratch feature
     * added licmak to include license into binary
     * new handling of XAutoRepeat, only turned off now when SPACE
       pressed
     * modified wave display (faster + nicer + incorrect (who cares
       anyway))
     * Makefile fixed by Adrian Reber <adrian@lisas.de>
     * bug fixes

   Version 2.1 (unreleased) 
     * added recording, playback of recording functionality
