OpenTracker 2.2.5: release notes

OpenTracker is an open-source, clean-room firmware for the original Polyend Tracker,
written from behavioural specifications. It contains no Polyend code, fonts, icons or
graphics, and is not affiliated with or endorsed by Polyend.

2.0 brings the newer Trackers features to the original hardware: 16 tracks, synth
engines, stereo samples, Mini/Plus-compatible project files and USB Storage mode.

We have an amazing community of contributors! People reporting bugs, helping each other, submitting fixes, creating presets, and sharing ideas. It's all of you who make OpenTracker better every day, and I'm really grateful for everyone putting their time and energy into making this firmware the best it can be!

This is no longer just project, it's our firmware, built and improved by all of us.

BTW - Performance screen fixes are in !

New in 2.2.5

• Performance screen as on stock (GitHub issue #86): every track starts with its FX
  off, and a press and release of the track's screen button turns them on. Before, all
  tracks started on, so a pad reached tracks you had not picked. Tracks 9-16 start off too.
• Performance labels: a track with its FX on has a red filled label. The name is light
  grey and the pattern number white; both turn black when the track is muted, so a muted
  track with its FX off shows a blank label.
• Performance filters: Low-pass, High-pass and Band-pass add their value to the
  instrument's own cutoff, also when the instrument's filter is off or of another type.
  Before, they started from an open filter (100 %, 0 % or 50 %).
• Performance FX on synth notes (GitHub issue #23): on every track 1-16 whose FX are on,
  Low-pass, High-pass and Band-pass move the synth's own filter cutoff, by the same amount
  as on a sample. The patch keeps its filter type. Panning, Delay send and Reverb send are
  added to the note's pan and sends. They follow the screen while a note sounds, also in
  its release. Two tracks on the same synth slot keep their own settings. PERC has no
  filter, so the filter columns do nothing there. Bit depth, overdrive, LFO speeds, start
  and end and direction still act on samples only.
• Synth release tails follow the Track Mixer: after the key is released, a synth note's
  release now follows the fader and mute of its track. Before, the tail played at full
  level. Release tails of muted or lowered synth tracks are quieter in existing songs.
• Sample Loader fixes (from a tester report):
  • Add next on a folder does nothing, as its greyed label says. Before, it opened the
    folder like Enter.
  • Add and Add next are greyed, and do nothing, when the SD card cursor is on a folder.
  • With Preview held, moving the instrument cursor onto an empty slot stops the sample
    that was playing, as letting go of Preview does. Before, it kept playing.
• Sample Playback, as on stock (GitHub issue #143): Delete with Start held or
  selected puts the start at the beginning; with End, the end at the end; with Zoom, the
  zoom back to 1. Before, Delete did nothing there outside the slice modes. Loop points
  stay where they are.
• Master held + Jog (GitHub issue #142): hold Master on another screen and turn the Jog
  to set the master volume. Letting go of Master now returns to that screen, as after a
  key. Before, it stayed on Master.
