A monosynth in three letters
Riled up.
Unmuzzled.
Beast.
Monophonic voice built around a screaming filter path. 303-ish attitude, spicier filters — completely unhinged. Yours for whatever you think it's worth.

Listen
Character.
Same notes, different chain — drive, rub and delay swap seats and the line keeps the scars.
Architecture
One voice.
The voice runs one way: oscillators into Rub, envelope into filter, dirt and echo on the tail. The sequencer doesn't just play notes — Param Seq reaches into the panel and moves knobs per step. Blend is the leash.
Main oscillator. Wave view picks a preset or Custom draw — that shape is the core tone.
±1…±24 st Range. B→A follows OSC 2 without rewriting this knob.
Second oscillator, phase-locked to OSC 1 until ×2 or relative Tune is on.
Same Range. A→B follows OSC 1 — laneable like any other param.
Crossfades OSC 1 and OSC 2 with equal-power balance so the middle stays loud, not hollow.
Shapes every note’s punch. Attack and decay set the bite; Accent hits harder on sequenced steps.
Path · RUB
Clean BLEP path — clear acid lines without the driven filter character.
Parallel filter + drive. Screech is Q, Oomph is drive, RA/RB sculpt shape and brightness.
Post-path grit. Warms or shreds whatever Rub (or Straight) just handed you.
Echo in milliseconds or synced divisions — space after the dirt, not instead of it.
Optional glue on the way out so wild peaks stay useful instead of clipping the master.
Sequencer
16-step sequencer·Sixteen steps per pattern. Sixteen pattern slots (0–F), chain them up, and let the sequencer own the voice while keyboard and MIDI ride along.
View · Pattern / Param
Step grid for the line. Drag the fish-eye pitch lane (C-3…C7), mark accent hits, and slide into destinations. Empty / release steps leave space. Arm capture to step through notes from keys or MIDI.
Shift the whole pattern while it runs. Hear it move — no rewrite needed.
Per-step overrides on MIDI-learnable knobs and toggles. Right-click a panel control to add that param as a lane. Active steps override the panel unless disabled; latches stay on the current pattern only.
Left is the panel state. Right is the overrides from the Param Sequencer. Shown only when the current pattern has lanes.
Play · Modes
Loop the current pattern only.
Walk the chain slot by slot, then wrap.
Jump to a random chain slot at each pattern end.
Motion · Key moves
Sequenced accents hit harder — velocity and envelope bite on those steps.
ALT: classic destination slide. SUS: sustain the prior note through the glide so the line stays glued.
Arm the record control. Keys and MIDI write into steps and advance (wraps after 16). Hard MIDI hits = accent; held notes = slide. Del / R clear or release then advance. MIDI-learnable.
Build a song path from patterns 0–F (up to 99 slots, 24 on screen). Letter end-caps page the strip; click a slot for Play from here and edit actions. CHAIN and RANDOM read this row; SINGLE ignores it and stays on the selected pattern.
