I'd love to know what's going on here. If I don't have this delay and trigger_save becomes true it never gets picked up. I only discovered this because it worked if I had other processing happening in the while loop. I tried throttling with a timer but that had no effect.
This is a port of the Torus (MI Rings) example to the patch.Init(). I've added a few enhancements to make it a bit more fully featured (v/oct and calibration, CV control of some params etc.)
I'll leave some comments about what has been modified from the Patch example.
