Description

Recreate:
Add:
* default 3oc (or any instrument)
* "C* ChorusII - Mono chorus/flanger modulated by a fractal -on FX-tab
* Turn "feedback" button above 0.5
* Play a note

Output:
Very severe distortion, and overclipping witch mutes the instrument.
Sound comes back, if the FX is muted
I cant remember i have seen this earlier, but i may not have tried this FX-plugin

Research direction

Reproduce the distortion in LMMS using the C* ChorusII effect, a default 3oc instrument, feedback above 0.5, and a played note. Start by locating the C* ChorusII effect implementation and its handling of feedback; done means the instrument no longer severely distorts, clips, or mutes at that setting, while the effect still operates.
