01 — FULL CONSOLE

The whole machine at a glance.

Oscillator, diode filter, generator, FX and arrange in a single window. Nothing buried in menus.

02 — SEQUENCER A/B

32 pads meant to be played.

Two rows of 16. Click = note, shift = accent, ctrl = slide.

03 — GENERATE

Ideas in one click.

GENERATE proposes, MUTATE varies, CLEAR empties. Style, scale, root and evolve.

04 — FILTER

The scream.

Giant cutoff with 18 dB diode, singing reso and biting accent.

05 — FX

And the space.

Distortion, HP, synced delay and space. Peak-time chain.

06 — ARRANGE

Your line, arranged.

Slots and chain with piano-roll and playhead.

01 — The voice

Real squelch.
Not an imitation.

From oscillator to accent, the full squelch path. Real plugin photos, not renders.

3-pole diode that sings up to tamed self-oscillation. The accent envelope opens cutoff and reso together.

One mono voice that cuts through the mix. Pre-drive before the filter so the squelch bites without muddying the kick low-end.

DIODE FILTER

18 dB that screams

Resonance that sings but never explodes: tamed and 100% stable. Ride Cutoff/Reso live — techno is played.

▦

32 SEQUENCER

Euclid + random-walk

Euclidean rhythm, diatonic walk, octave jumps and slides on short intervals. 7 scales, 5 styles, deterministic seed.

≋

FX TECHNO

Dist → HP → Delay → Space

Serial chain built for peak-time: tube/diode/hard, synced ping-pong with damping, short reverb, M/S width and soft limiter.

✦

GENERATE / MUTATE

Never get blocked

GENERATE creates a pattern, MUTATE varies it live, CLEAR empties it. Evolve adds controlled chaos. You always get a new line in 1 click.

Infinite ideas, always in key.

The generator mixes Euclidean rhythm with diatonic random-walk. You pick style, scale and root — it suggests, you rule. Deterministic by seed: if you love it, it repeats exactly.
