Fantasma
Firmware for the M-VAVE FM-1 · 1.1

Fantasma

Felucca's thirteen engines and sequencer, plus an ambient machine: a Pad that writes its own chords, bells that grow like a garden, an endless noise of sea, rain or vinyl. In a neon skin, with a ghost.

What's new in 1.1

2026-10-16

Tape sounds, in the manner of Boards of Canada:

  • WOW: a preset can now set the LFO for a slow, free wobble of the pitch, a worn tape that slows down and speeds up again, and its SPREAD and GLIDE. The presets before 1.1 do not use them and sound as they did.
  • Six new sounds with it, at the end of their engine's list (the numbers of the others do not change): NOSTALGIA (ANALOG, a detuned pad; on the Pad too), HAZY LEAD (ANALOG, a mono triangle with a slow delay), TAPE EP (FM6, the tine piano with a lot of chorus), FADED CHOIR (VOICE; on the Pad too), MUSIC BOX (BELL, a toy bell drifting in pitch) and VHS HISS (AMBI, the hiss and crackle of a running tape).
  • Sounds on the website: eight short pieces, played by the firmware itself on the four tracks.

Four parts, one ghost

The FM-1's four tracks become four roles: PAD, LEAD, ECHOES and NOISE, each with its own colour and sounds made for it. Press OCT+ on the AMBIENT page and the machine draws a whole scene at random.

What's inside

Everything Felucca 1.5.1 does, and an instrument for slow, warm, drifting music on top.

The ambient machine

SEQ › AMBIENT: OCT+ picks the sounds, a scale and a key, switches the Pad's progression and the bells on, and sets long envelopes and reverb. The generators keep playing with the transport stopped.

AMBI, the noise engine

Sea, surf, storm, wind, stream, fire, vinyl, rain, cave drip, crickets: filtered noise with swells and crackles. REL at its top means INF: a drone that never stops.

BELL and the garden

Soft two-operator FM bells. Turn DENS up and they play themselves: four loops of 13, 17, 23 and 29 steps drifting apart. The keys choose which notes grow in the garden.

A Pad that writes chords

SCL › CHORD gets DENS, BARS, CHORDS and SEED: the Pad plays a progression of its own in the key, slowly changing, never the same twice.

OMNI, an Omnichord

The black keys become chord buttons (F C G Dm Am Em G7 E7 D7 B♭ A7 in C), the white keys strum the chord. ENV makes it minor, LFO adds the seventh; OMNI H holds the chord.

Tails up to 90 seconds

The AMBI reverb: HALL's smooth stereo with tails from 7 s to about 90 s. A fresh start uses it, and every Echoes sound loads with reverb and delay.

Warm sounds per part

Browsing follows the part: slow pads (WARM PAD, TAPE STR, DUSK PAD…), fifteen bells (THUMB, AMBER, SILK, HALO, DEW…) and the AMBI beds.

The neon look

ECTO: near-black with a blue cast, ice-white text, cyan values, magenta for the active thing. An animated ghost at power-on, and one on the AMBIENT page.

All of Felucca underneath

Thirteen engines with FM6, a 64-step sequencer with parameter locks, chance and ratchets, songs, arpeggiator, a modulation matrix, INSERT effects and MIDI LEARN.

Sounds

Eight short pieces, each played by the firmware's own engines on the four tracks, as the FM-1 plays them: no effects added afterwards.

Safe to try

Custom firmware should never be a one-way door.

Install from the browser

Chrome or Edge, a USB data cable, two minutes. The installer checks the package before writing and asks the FM-1 what it runs afterwards. An interrupted install resumes.

USB rescue

Hold OCT− while switching on (or let two starts fail) and the FM-1 starts a small rescue mode with only USB, ready for a new install. The boot code itself is never written.

Back to official

The installer can put M-VAVE's official V15 firmware back at any time, after saving your music to a file.

Ready?

Try it first in the browser, no FM-1 needed, or install it now.
