Is it possible to layer your own loops on top of one another? Be fun with a mic plugged in for vocals... I'd love to see a 'how to' video :)
For this you want to experiment with some of the sample modules in Modular Play, they’re quite buggy (they were the last thing I implemented before burning out a little) but I’ve written some good experimental sounds with it: https://orllewin.uk/playdate/ModularPlay#Sampling
