Oscillators Frequency Piano Roll

Perhaps you have a more detailed idea about how this should work?

Sure! Linked to another thread.

It's a pretty big bug unfortunately. Faust DSP Classes are not initialized for instruments in the interpreter backend (lookup tables and so forth). If possible, you should only use the LLVM backend for instruments until the next release.

Got it. I'll use LLVM from now on (for now).
