I'm using the Bela Pepper to run some RNBO code that consists of an fzero~ object and some other things that sample notes I'm playing on the violin and distributes triggers, envelopes, and pitch CV in fun ways through the 8 analog CVs. I have the project working to my satisfaction with a block size of 512 and 22050 sampling rate so I can use the 8 analog channels. This works fine when I run the project from the IDE (CPU ~22%). When I disconnect the Bela from my computer and run it in my Eurorack case, however, I get a lot of distortion. When I plug Bela back into my computer and launch the IDE, I see constant underrun errors ("underrun detected: 1 blocks dropped") in the console.
Perhaps it's worth mentioning that I'm using the commands suggested by giuliomoro to get the RNBO code to run on boot (post title: "RNBO project won't run on boot"), since this hasn't been working for me if I set the project to run on boot in the IDE. Not sure if this is relevant.
I'm using a brand new Intellijel 7U case. All of my other modules are working fine.
