Mubu.process error message: "invalid buffer index in message bang"

hi guys

I’m trying to automatically chop the most recent buffer recorded into a multibuffer~ once recording has finished.

first recording usually works, second one causes the error message in the console. setting the buffer to the second to last index, i.e. “2” when last recorded buffer index is “3” tends to fix the issue.

does anyone else get this error message: “invalid buffer index in message bang”?

another strange thing: if I set the bufferindex to ‘all’ for mubu.process, the buffers are only actually processed if the imubu window is open. if not, only the first buffer is processed.

really weird. I’m running Max 8 on Windows. can anyone reproduce this?
