Hello ~ I'm a little new to bela, I usually run PureData stuff on my laptop. I'm getting the underrun error 10 times a second and also "Your code is printing to the console too quickly. Check your audio thread for print messages." which I presume are related. Any idea how I can fix this? I am getting clippy playback 
If the pd patch is hard to read, what is basically happening is the mic in is being recorded into 'mumble' (when threshold is met), and then replayed (after a delay) and fed into a vocoder, where the pitch is controlled by a random melody generator, with some variation in note duration.
