v2.8.2

- Patterns wouldn't scroll sometimes when starting to play, fixed.
- Note volume from channels (volume columns and effects 03) are now handled
  in the velocity sent to midi output.
- Changed LCTRL + F1 / F2 (Decrease / Increase editing step)
  to LCTRL + F2 / F4 due to Mac OS "interfering".
- Fixed Midi handling on Linux and Mac OS.
- Fixed the keyboard shortcuts on Mac OS.
- Typos in the manual: Transpose to 1 octave higher shortcuts
  are LCTRL + K and LCTRL + LSHIFT + K.
- Replaced pink noise with triangle waveform in synth.
- White noise is now twice as loud to be on par with other waveforms loudness.
- Added a function to hard sync OSC 1 to OSC 2.
- Inserting or deleting a track didn't modify the other patterns data.
- Fixed an ugly visual bug that occured when changing colors during playing.
- Added tracks header foreground color modifier.
- Sub oscillator can now be scaled from oscillator 1 by semitones.
- Maths combiner functions are also used for sub oscillator.
- Fixed various bugs here and there.
- VU meters are now displayed on a single line and a much less sensitive.
- Removed support for antediluvian NoiseTrekker 1/2 modules & instruments, 
  they were only supported for salvage and conversion purposes.
- Saving a pattern without any currently selected block
  will save the entire pattern into the file.
- New logo !

v2.8.1

- Channels LFO carriers are now properly reseted at playing start.
- Channels LFO data can now be sent to the channel filter cutoff, 
  volume and panning.
- Added a channel LFO frequency scaler.
- Added these effects:
  - 43: Set channel LFO frequency.
  - 44: Set channel LFO frequency scale ratio.
  - 45: Set channel LFO amount to send to the channel filter cutoff.
  - 46: Set channel LFO amount to send to the channel volume.
  - 47: Set channel LFO amount to send to the channel panning.
- Fixed a very old NoiseTrekker bug where LFO values sent to the channels
  filter were lost because they were too big and clamped.
- Fixed a nasty regression that occurred in 64 bit compiled versions.

v2.8.0

- Added a function to negate the current palette.
- Added two functions to rotate the current palette on the left or right.
- Re-arranged bitchbiker.ptk and added it into the official list of modules.
- Changed the behaviour of the single step mode, plays only stops when
  enter (or return) key is depressed and only the current pattern is played
  (press Left Shift to go into song mode).
- Added a function to transpose a range of instruments.
- Patterns modifications functions are only active when edition mode is on.
- Transposition functions now keep track of last used instruments to be able
  to transpose relevant notes used without instruments.
- Stopping step mode will keep edit mode intact.
- Sample "Maximize" (Max) is now called "Normalize" (Norm) in samples editor.
- More visual feedback for currently played sample in samples editor.
- Added the option to show/clear leading zeroes digits in patterns.
- Added patterns sliders edition mode (check manual for explanations).
  Note: This mode can be quite CPU intensive.
- Fixed various bugs in patterns edition.
- Channels VU meters were drawn way to many times over each others, fixed.
- Fixed the audio levels of the channels VU meters.
- Modified the reverb (should sound better (?)) also added a damp parameter
  (had to rework some modules due to this).
- Added effect 2C: Set reverb damp ratio.
- Improved the volume ramping.
- Added LCTRL + LALT + HOME / END keyboard shortcuts (jump to top/first track
  or bottom/last track of a pattern).
- Added Enter or Return keys for single step play.
- Fixed channels multi polyphony allocations.
- Fixed the fullscreen mode switching under AROS.
- Added an OpenGL executable in AROS distribution (ptk_aros_ogl)
  for some reason i don't explain it may be slower than the regular one, 
  your mileage may vary.

v2.7.5

- Sample editor tries to keep loop information intact whenever possible.
- Synth distortion can now have positive or negative values.
- Synth ENV 1 & 2 can be directed to drive synth distortion.
- Synth LVO 1 & 2 can be directed to drive synth distortion as well.
- Removed broken instruments and presets from distribution.
- Fixed a couple of bugs here and there.
- Added replay routine support for AROS.
- Added global stereo VU meters view for each channel.

v2.7.3

- Samples data & properties weren't properly recalculated after
  samples editor operations often leading to a crash
  when a song was being replayed at the same time.
- Implemented a more straightforward individual tracks zooming mechanism.

v2.7.2

- Fixed a long time running bug that would make the tracker to crash when
  loading or messing with the instruments.
- Fixed a small visual bug in patterns display.
- Patterns font size can now also be doubled vertically.
