Mighty Arp

A chance arpeggiator synth for the M-VAVE FM-1

Custom firmware for the FM-1: a 4-op FM and subtractive hybrid synth built around a chance arpeggiator. You choose the notes, the arp decides when they play. Hold a chord, set CHANCE, and let it create melodies.

What it does

A chance arpeggiator. CHANCE decides how many steps play: at 100% a classic arp, lower and it thins out into a melody. Thirteen modes, swing, humanize, octave jumps and velocity spread.
Chords. Each note a chord in your key and scale (triads, sevenths, lush and open voicings), strummed if you like.
A 32-step sequencer. Write steps from the keys, transpose them live with a key, ties at full gate, and the same chance.
64 sounds. Keys, bells, plucks, basses, leads, pads, percussion and weird noise textures, from four FM operators with analog-style waves, a filter and its envelope.
Space. A chorus, a ping-pong delay and a reverb with shimmer.
Your own presets. Sixteen slots, each keeping the sound, the arp, the sequence and the effects.
MIDI. In and out over USB and the TRS jack, with clock in or out. Over USB it is also a sound card.

Installing is at your own risk; the installer can put M-VAVE's own firmware back ("Back to the stock firmware"), as can M-VAVE's updater, M-UPGRADE, from m-vave.com/download. Mighty Arp is by Nick Culbertson. M-VAVE and FM-1 are trademarks of their owners. Mighty Arp is not affiliated with M-VAVE.
