This is a demo for the new GBA 16-step sequencer STEPPER. It features an intuitive workflow inspired by Elektron instruments with per-trigger parametrization that allows access to the 4 DMG sound channels in the console (2 square waves channels, 1 custom wave channel and 1 noise channel). Supports 4 banks of 8 patterns that can be queued for live performance.
