REAL DOOM ENGINE · EXPERIMENTAL FIRMWARE

Wrong instrument.
Right kind of
chaos.

Your synth has a dark side. Nine levels, three weapons, and a very different use for those piano keys.

The browser builds the correct firmware for your model using a checksum-verified base. No command line, and no firmware file upload needed when the automatic download is available.

Before you cross over

This replaces the synth application. Back up your projects first. There are no game saves. Normal USB installation works from Doom builds with USB updating enabled, stock firmware, or a compatible synth updater. Earlier Doom builds, or an interrupted flash, require a XIAO recovery adapter before updating. Keep it available in case recovery is needed.

Release 16 has passed build and package checks for all three models. Detailed hardware validation is ongoing. Keep power connected during installation.

PrepareUse desktop Chrome or Edge. Connect only your selected instrument directly by USB and leave it powered on. Close Studio and other MIDI apps.
BuildChoose your exact model, then build the firmware here. SMK uses the matching official Pro 016 or Elite 016 base.
InstallConfirm the notice, grant MIDI access and keep USB and power connected. Wait for the confirmed restart, then play.

Restore original M-VAVE firmware

I have backed up my synth data and have a recovery adapter. I understand this experimental firmware replaces the synth.

Download trouble? Use a local base file

The same SHA-256 and model checks apply. FM-1 accepts the pinned Felucca Salt14 base; SMK accepts its official 016 .fwsc. The file stays in your browser.
