Playing with Faust

Hi folks,

I think this is going to lead to, “How do I yank midi off my Striso/Will it help.” I’ve been working on doing custom instrument sounds with the Striso, particularly on how to get it to behave differently between plucking and pressing. In recent work on the tambor, I’m running into an error that might mean that I’m running out of memory:

The error I’m seeing:

I’ve attached the version of (1.7 KB) that throws the error. Of interest, if on line 106 you change osc to triangle it works, which also smells like a memory issue.

I don’t especially care about midi for this. For those who know more than me, will I be able to buy a substantive amount of memory by dumping the midi portions from the build? How much pain and suffering will I likely get trying to do it?
