a portable and affordable audio looper with quantization
how it works:
- audio input/output via a usb audio adapter
- midi clock signal via a midi-usb cable
- raspberry pi (with Raspbian) routes audio through sooperlooper
- buttons interface with sooperlooper (via
looper.py) to control recording/playback/saving/loading/etc.

hardware:
- raspberry pi (3B) with USB audio interface
- neotrellis pcb and silicone buttons for controlling the looper
- laser-cut enclosure (
static/photos/design.ai) - full parts list with costs
software:
- python 3 with various packages (listed in
requirements.txt) - jackd: for routing audio
- sooperlooper: for looping
python3 looper.py -v -s
the loops will be time quantized if you provide a clock signal via a midi-usb cable
