Video: Looking to add some loops into your music? DIYer Szymon Kaliski used a Raspberry Pi to power a four-track audio looper, complete with toggles and potentiometers. The end project here allows you to record four eight-second loops, then independently adjust volume and feedback. As you'd probably guess, this is a pretty complex project, but Kaliski's GitHub page supplies the software and part of the internal wiring. At the end of the day you'll have an incredibly cool little looper. Combine that with a MIDI sampler and you're well on your way to full Pi-Powered band.
