Description

Using LMMS 1.1.3 on Windows 7 x64 (all updates)
1. Removed all other instruments from default Song Editor
2. Added OpulenZ instrument
3. Put a few notes in Piano Roll
4. Set loop points (4) and enabled them, hit play
5. Fiddled around with OpulenZ settings, all working fine
6. Fiddled with Global automation of Pitch on OpulenZ, didn't seem to have any effect?
7. Decided to hit STOP button for some silence
8. A constant tone (sine-wave I think), continues to play afterwards
9. Must mute or set OpulenZ volume to 0 for silence, but tone continues if unmuted or volume increased
10. Must delete OpulenZ instrument to make it stop

Not entirely sure which fiddled bits are relevant to reproducing problem

Research direction

Reproduce the issue in LMMS using an OpulenZ instrument, loop points, playback, and the Stop button, then narrow down whether the OpulenZ settings or global pitch automation matter. Confirm that a constant tone remains after stopping and identify what action silences it. Done means the reproduction no longer leaves OpulenZ playing after Stop.
