Four-Operator Engine
Wavetable and sample sources per operator, with FM and PM routable between all four — including self-modulation taps.

PSYDENOTE Wavetable · FM · Arp · Sequencer
Four operators with wavetable and sample sources, FM and PM between all of them, a dual filter bus, eight FX units and a 24-slot modulation matrix — wrapped around a layered arpeggiator whose two rows run on their own clocks.

The instrument
Built to be patched until it hurts.
Everything lives on one screen — no modal diving, no hidden tabs. Drag a cable, paint a lane, roll the dice.
Dual Filter Bus
Two independent filters — low-pass, high-pass and band-pass with cutoff and resonance — with per-operator routing into A or B.
Eight FX Units
Delay, reverb, chorus, flanger, phaser, distortion, a multiband compressor and a parametric EQ — reorderable in the chain.
Modulation Matrix
Three envelopes, three LFOs (add more), an audio follower and 24 routing slots. Grab a cable and drop it on any knob.
Mega ARP & Sequencer
18 patterns, a green and a blue row each running its own clock, seven coloured step lanes and a chaos dial that randomises the lot.
Sampler & Drag-Out
Resample the synth, slice it on the waveform, then drag the take straight out of the window into your DAW.
Arp & sequencer
Two rows. Two clocks.
The green and blue ARP rows each carry their own rate, octaves, gate and chaos amount, so they drift against each other while staying locked to the bar.
- 18 patterns — up, down, converge, as-played, walk and more, per row.
- Seven step lanes — on, probability, pitch, octave, velocity, gate and slide.
- Chaos dial — one knob scales every dice on the panel, from dead-straight to fully unhinged.
- Scale snap — pick a key and scale, every generated note lands in it.
