Current Behavior
  • beat with fade out (or volume swell)
  • after it: track silent until the end of the song
  • changeTrackVolume(): no effect (volume × 0 = 0)
Expected Behavior
  • fade out = only its beat
  • next notes: normal track volume (like Guitar Pro)
Steps To Reproduce
  1. Track with: fade in on a beat, fade out on a later beat, more notes after
  2. Load the file
  3. Play the track (solo)
  4. Notes after the fade out: no sound

Anything else?

Cause:

  • MidiFileGenerator._generateFade
  • fade out → VolumeCoarse down to 0 (primary + secondary channel)
  • no reset after

Fix idea:

  • fade out + volume swell: add VolumeCoarse = track volume at beatStart + beatDuration
  • track volume = playbackInfo.volume, or current volume automation if any
