RHYTHMERINSTALL JAZZY.
Explore the unheard. Connect your FM-1, save your music and review the target before installing.
One install. Two Break loops ready.
JAZZY includes Break A / Amen and Break B / Think by default. Both are two bars at 160 BPM, mono 16 kHz / 12-bit. The official V15 recovery file is included and verified automatically.
Desktop Chrome or Edge · USB data cable · final device-write confirmation required.
A / Amen — The Winstons, “Amen, Brother”.
B / Think — Lyn Collins, “Think (About It)”.
Recording rights are separate from the firmware license. Rights-holder authorization for redistribution of these copies has not been obtained.
BREAK AUDIO SOURCES & RIGHTS →For your first install, back up your music and start from the official V15 firmware. Use RETURN TO V15 if you are coming from another custom firmware. Save a backup with that firmware’s own editor first. A supported JAZZY or RHYTHMER build can export a musical backup here. V15 recovery can make custom music unreadable.
Firmware updates can erase music, presets or samples, leave the FM-1 in update mode or require hardware recovery. Testing of this build on physical devices is limited. Back up first and keep power and USB connected until the installer verifies the restart.
JAZZY is an independent community project with no affiliation, sponsorship or endorsement by M-VAVE. To the extent permitted by law, JAZZY is provided without warranty and its authors and contributors disclaim liability for device damage, malfunction and data loss. Statutory rights and liability that cannot be excluded still apply.
Recovery is already here.
The installer checks package size, SHA-256 and firmware identity. For JAZZY it also verifies both embedded Break banks. The recovery file is the unmodified official V15 image from M-VAVE’s FM1 Open repository.

Package sources and official V15 file override
Pinned official source and hash · Apache-2.0 · Recovery attribution
Use the included recovery file or select the exact same official V15 image. Other versions and modified files fail verification.
One FM-1. A data cable.
Use desktop Chrome or Edge over HTTPS or localhost. Connect one FM-1 with a USB data cable, set it to USB Device mode, stop playback and close DAWs, other installers and USB MIDI editors. Install handles connection and inspection automatically. Use Connect & Inspect to check the device identity separately.
Not connected.
Keep the music first.
The installer reads projects, sounds and settings from compatible custom firmware and checks each archive object. Musical backups do not contain Break audio. Keep your original audio files separately and restore the archive with its source firmware’s editor. RHYTHMER drum-kit tracks may need a new sound assignment in JAZZY.
DOWNLOAD BACKUP ↓Inspect the device first.
Review the JAZZY installation.
One firmware transfer installs JAZZY and replaces Break slots A and B with the included Amen and Think loops. Save any custom loops separately before continuing.
Nothing has been written.
DOWNLOAD DIAGNOSTIC REPORT ↓If an update is interrupted.
Reconnect with stable power and inspect the FM-1 again. Use the same installer, browser and target package to resume a matching saved update. A dark FM-1 that does not appear over USB may need hardware recovery.
V15 recovery writes official stock firmware and checks that the FM-1 returns as FM-1_015. It does not import custom projects into stock firmware.
