  and adjust time controls according to the sample rate
+ sample rate/fragments/stereo/bits controls on the fly
  + sampling params dialog

0.3.0
+ DirectSound API Win32
  + fix buffer over/underruns (48000)
  + fix latency autowah
  + DirectSound control in sampling params dialog
  + optimize loops in the audio thread

0.3.1
+ noise gate
+ new overdrive effect

0.3.2
+ GTK2
  - test on Windows
+ equalizer effect
  + 5kHz limit problem
+ process all in floats to decrease SNR ? Convert only on input and output ?
  (as IFDEF)
+ distortion
+ correct build files for MSVC6.0
+ help contents on Windows 2000
+ sigfault on help contents with netscape, linux
  (looks like it is a netscape own error)
+ review the docs, especially build notes for the console MSVC users
+ check autowah on windows
+ better presets for distort1 and phasor
+ autowah breaks the updated low and high values

0.4.0
- allow to read help only with sound off, or auto-stop the sound
- tooltips to the noise gate window with important notes
- remove mix control from autowah
- pitch shifter
- load preset files from the command line
- group effects and give it meaningful names
- new noise gate effect
- i18n
- effects with a sinusoidal phase/amplitude shape (tremolo,chorus)
  offer other shapes (square, triangular)

0.5.0
- tuner
?- external pedal and switch

0.6.0
- play .wav in the background

Ongoing bugs (misc):
- convert the names of presets to UTF8 strings, before append it
  to the bank list, as recommended by GTK-Win32 manual.
- bug with GTK critical error on finish

Misc something:
- port to wxWidgets ?
- have a text boxes connected to the sliders, to directly edit the values
- how to swap a slider controls, to make a bottom be on top and vice versa ?
  So we move the slider up to increase the value, instead of moving it down...
