Oversampling is 8x by default

In linux as vst3 and lv2
this is perhaps the cause of most of the issues with high cpu and glitchy sounds

Ah hmm haven’t seen that myself.
Could explain some of the issues.

My impression is that it is recalled per patch, when you set it low and select a different patch, it changes.
If that is true, maybe an optional global override could be useful.
“FM Drum Circle” uses 8x for example.
