Description

Drooper - a drum machine for looper pedals

A drum machine based on Raspberry Pi Pico, played by capacitive touch, and designed to output to a looper pedal.

If you have ever been frustrated that your guitar with magnetic pickups can't do that KT Tunstall "bashing on the guitar body percussion" trick, this one's for you - a drum machine with guitar body bashing noises built in.

Updated 15th August 2025 to tweak the LPF which was stopping the design work correctly with a Ditto Looper 2 pedal.

Now tested, works brilliantly.
