New Thing – StompByte!
A few years ago I cobbled together a quick build of a digital stompbox using the PCMAudio code running on an ATMega328p to play 8-bit audio samples off one of the PWM pins. I built it into a cheap plastic sustain pedal, used it for a duo gig with a friend, then stuck it in a drawer. Last weekend I decided to resurrect it. I added a few more samples, added a step patterns feature, and put it in a nice aluminum enclosure with a more robust stompswitch – and the StompByte is born!
The sounds are very low-res from the resampling to 8kHz, but the kicks and other percussion have a nice feel to them nonetheless and feel good to play to. I feel like the rough quality and inexpensive build is in the same DIY spirit as the classic wooden stompbox with piezo pickups. I stuck some Mario sounds in too (mostly for funs, but hey maybe someone will use them). Planning to sell this as kits and as finished builds on Tindie. Perhaps get some friends to build a few artsy enclosures for them?
