Create a 4-Track Looper With Raspberry Pi
Want to add loops to your music? Master Shimon Kaliski used a Raspberry Pi to power a four-channel audio looper with switches, potentiometers and more.
The final project here lets you record four-, eight-second loops and then independently adjust volume and feedback. As you probably guessed, this is a fairly complex project, but Kaliska’s GitHub page provides the software and some of the internal wiring. In the end, you have an incredibly cool little looper. Combine that with a MIDI sampler and you’re on your way to a full Pi-Powered range .
