Switching wavetable files causes crash when there is a pitch modulator present.
-
This one took my a while to track down but I think I finally found the culprit.
Basically, if you have an active pitch modulator of any kind in the chain and you try to switch wavetable files (while sound is playing).... kaboom!I was hoping someone would please help me confirm it. I put together a snippet with everything you need to recreate it. You just need to provide a few of your own wavetables and use the comboBox to switch the wavetables while sound is playing. I am using an ahdsr envelope to modulate the pitch, but you can use any other modulator to try it out.

@CyberGen confirmed, it happens here too

@ulrik Thank you.

I've tried many different ways to bypass the issue to no avail. Including:
1- Zeroing out the intensity of the pitch mod before the callback switch and recalling it after.
2.- Bypassing the entire pitch modulator before the callback switch.
3.- MidiMuting note before the switch.
4.- allNotesOff(); before the switch.
5.- Bypassing the Wavetable Synth before the switch
6.- All of the above at the same time.The crash still happens every time.
Please let me know if you think of another way to bypass this problem.

@CyberGen This also happens for me but only when the pitch mod is bidirectional. So if you can get away with unidirectional, I'd start there!
-
@ally good tip! I hadn't notice that. Thanks for sharing it.
I don't think I can really get away with using only unidirectional pitch mods though. This is the biggest issue I have with my current project. Switching wavetables must happen without issue for it to really work.
thank you.

@ally Did you try it with a unidirectional LFO? or pitch mods other than an envelope?
I can confirm that if you load a unipolar pitch envelope the crash does not happen. But it seems to be the exception. It is happening to me with other unipolar pitch mods like LFOs and even a simple constant modulator. It is also crashing sometimes when attempting to save the xml while sound is playing.
