Description
Spagyros chains three effects in series, one per row of pots: the left pot sets depth and the right pot a character macro, a button cycles each row's effect, and pressing two buttons bypasses everything. The nine effects include a DJ filter, bit crusher, riser, chopper, beat repeat, reverse/slow, phaser, DJ echo and a space reverb, each with extra parameters set from the web programmer and stored in presets. It follows a 24 PPQN external clock and can record its stereo output to the SD card as WAV files.
Install notes
Flash from the Hermetic Modular web programmer (hermeticmodular.com/program) over the front USB-C port in a Chromium-based browser. SD recording needs a FAT32-formatted card.
