STUTTER - Reactive Glitch Sequencer for Gameboy - Cartridge - V46

STUTTER, a 4 voice MIDI step sequencer for the Game Boy

Turn a real DMG or Game Boy Color into a pocket groovebox. STUTTER sequences all four sound channels; two pulse, wave, and noise; with 32 patterns chained across a 128-step song arranger.

Every voice gets full sound design: ADSR envelopes, vibrato, tremolo, detune, pitch envelope, portamento, and a tempo-synced arpeggiator up to 1/64.

Hold a button while it plays for live glitch FX; stutter, drone, reverse, beat-loops, half-time, octave jumps, tape-stop/spin-up pitch bends, and four live arpeggios. Sync to your rig over MIDI clock as a slave or master, and keep three battery-backed songs on the cart.

Four voices

Sequence the Game Boy's full sound chip, two pulse channels, the wave channel, and noise, for leads, bass, chip-organ pads, and drums all at once.

16-step patterns, 32 of them

Lay down ideas on a 16-step grid where every step carries its own note and its own instrument, then bank up to 32 patterns to build from.

128-slot song arranger

Chain patterns across a 4×4 grid spanning 8 pages, 128 slots in all; and drop a loop marker anywhere to set the groove running.

Deep per-voice sound design

Shape each voice with a full ADSR envelope, vibrato, tremolo, detune, octave, pan, portamento glide, and a one-shot pitch envelope — no two patches have to sound alike.

Tempo-synced arpeggiator

Per-voice arps that lock to your tempo, from whole notes all the way down to 1/64; choose up, down, bounce, or random, and dial in how many notes it sweeps.

Live glitch performance mode

Hold a button while it plays to mangle the groove on the fly: stutter, drone, reverse, beat-loops, half-time, octave jumps, tape-stop / spin-up pitch bends, and four live arpeggios; instant, hands-on chaos.

MIDI clock sync, in or out

Slave STUTTER to your DAW or hardware over MIDI clock, or make it the master and drive the rest of your gear.

Battery-backed saves (on carts with this ability)

Keep three full songs on the cartridge with custom names, plus an automatic live-save so your work survives a power-off.
