LOS RITMOS

Fourteen styles a PERC track plays by itself while the sequencer runs, and the lines the ARP plays over a chord. Every sound here is the firmware's own, recorded from it.

EL KIT

On a PERC track every key is a drum: 22 Latin and Caribbean percussion instruments, synthesized, no samples. Play them here.

Four kits (SALSA, PERREO, BOMBA, TIPICO) retune them, and the HUMAN knob loosens every hit. These are KIT SALSA's.

INSTALL IN A MINUTE

On a computer, in Chrome or Edge, with the FM-1 on USB.

Back up first. COQUÍ keeps its own saves and never reads another firmware's: save what you have with your current firmware's own tools before you switch. Once COQUÍ is on it, its editor backs up its sounds, slots, settings and samples.
Get COQUÍ. Download coqui.fwsc from the releases. Once COQUÍ is on the FM-1 Firmware Hub, pick it there and press install instead.
Install it with any FM-1 installer that takes a .fwsc file, or from a terminal: python3 tools/fm1_install.py coqui.fwsc. Switch on, wait for the coquí to sing.

Unofficial firmware, not made or supported by M-VAVE. Tested on a real FM-1 (from the official V15, from another firmware, an interrupted update resumed), but every FM-1 is its own: install at your own risk. Hold OCT- while switching on for the USB rescue; the Firmware Hub's Rescue page brings back any FM-1, stock firmware included.

NEW IN 1.0

PERC: 22 percussion instruments synthesized on the FM-1, on their own pool of hits, never taking the bass's or the keys' voices.
GROOVE: 14 styles with accents, ghost notes and fills, from dembow to bomba yubá in 6/8.
The lines: the ARP plays a tumbao, a piano montuno, a guajeo, merengue and bachata bass over the chord you hold, on the groove's bars.
44 factory sounds made for it: baby bass, montuno piano, cuatro, tres, mambo brass, boogaloo organ, steel pan…
Ten factory kits, each with its style. The kit, the groove and the hits are saved in your sounds, slots and project.
The mood: GENERATE in the clave (NOCHE, CALLE, FIESTA), AMBIENTE scenes for the effects (from a backyard to a dub to an old AM radio), and a HOME screen where the coquí sings over a conga a track and falls asleep when you stop.
A noche tropical palette (ROSA, MANGO, MAR, LIMA) and a coquí that sings at start-up.
Newer FM-1s (sold since autumn 2026) save and update too.
