I found a reproducible bug in SoundBox V1.2.1 regarding to bypassing a modulation.

Steps to reproduce:

- map any parameter to any modulation
- click on “bypass” in the modulation window
- plugin crashes

Tested in the following DAWs:

- Bitwig Studio 6 Beta 17 (CLAP, VST3)
- Reaper 7.59 (CLAP, VST3, LV2)
- Renoise 3.5.4 (VST3)

Log from Renoise:  
”Renoise LOG\> Vst3Plugs: Plugin ‘Audiomodern: Soundbox’ crashed while calling its EventHandler::onFDIsSet functions!”  
After the error window in Renoise appeared, I can click it away with “ok” and also can deactivate the “bypass” in SoundBox again.

Reaper crashes completely.  
Bitwig just states that the plugin has crashed.

I hope it helps a bit.

Best regards,  
Christian
