Midi sustain working when envelope is on #3730
Conversation
|
Cool! Issue: When I take a note with long decay, I release by letting go of the sustain pedal and, while it's decaying, hold it at a new level by pressing the sustain again. I don't think this is wanted behaviour for a synth although it very well could be how some machines work. |
|
I think it would have been easier if the sustain pedal stuff had been all done in |
Do you mean long release?
Do you want that when the sustain pedal is pressed again, it doesn't affect the release (that keeps fading out to silence)? |
Oops, yes... :)
Yes. If you let go of the sustain pedal, all keys that aren't pressed down should go into release and if you press down the sustain again this shouldn't hold released notes again. This is my understanding of how a common envelope generator should behave. |
|
Well, I don't know the common behavior. However, I think that sustain pedal shouldn't pause releasing. |
|
Done, now release isn't paused when sustain pedal is pressed again. |

I think you should adapt the original code to your format.
n->isReleased() == false --> !n->isReleased()

you stick this to the end of NotePlayHandle but it belongs, logically, together with isReleased().
Please move isReleaseStarted() to after isReleased() and m_releaseStarted to after m_released.

Done, addressed your indications. |

@zonkmachine Are you going to backport this? Edit: Done via 31126b0, by @zonkmachine. |

Fixes #3537.
When sustain pedal is pressed
NotePlayHandle::play()doesn't enter release phase.And in
InstrumentSoundShaping::processAudioBuffer(), the envelope's release is posponed until the sustain pedal is released.
