Description
Patterns up to 64 steps (stock stops at 16) with per-step ratchet, chance, gate and length, pattern chaining into songs, four knobs on every screen, and Bluetooth MIDI clock between two FM-1s (from version 97). Presets and patterns are kept across installs, and the installer can restore M-VAVE's firmware. Distributed free from the author's page; a Ko-fi tip jar is linked.
Install notes
Install page works in Chrome or Edge (not Firefox or Safari) over USB and takes under a minute. Two free preset packs (8-Bit, Virtual Analog) overwrite presets 97-128, so back up first. The same author ships SMK-37+VA for the SMK-37.
