Bouncing ball

Section titled “Bouncing ball”

A classic self-patched MATHS cell: CH 1 cycles, its own output retriggers CH 2 which in turn shortens CH 1’s fall. The harder the ball bounces, the faster it falls — a physical feedback loop drawn as a feedback cable.

MATHS:
* CH 1: Cycle ON
* CH 2: Attenuverter ~2 o'clock


- MATHS.CH 1 (OUT) >> MATHS.CH 2 (In)
- MATHS.CH 2 (Out) >> MATHS.CH 1 (Fall CV) // shortens fall each cycle

Quadrature LFOs

Section titled “Quadrature LFOs”

Two non-cycling slopes cross-trigger each other’s EOR/EOC — the result is two LFOs 90° out of phase, useful for stereo movement or any time you want two related but distinct modulators.

MATHS:
* CH 1: Cycle OFF, Rise + Fall matched
* CH 4: Cycle OFF, Rise + Fall matched

Simple chain

Section titled “Simple chain”

The classic subtractive voice: oscillator, filter (with envelope modulation), VCA (with LFO tremolo). A good starting point for almost any patch.

- Oscillator (Out) -> Filter (In)
- Envelope (Out) >> Filter (Cutoff)
- Filter (Out) -> VCA (In)
- LFO (Out) >> VCA (CV)

Filters with variants

Section titled “Filters with variants”

Two filters in series with [bracket] subtitles to disambiguate. Useful when you want a band-pass from discrete HP + LP stages, or when you want to show which variant of a module is in use.

- Oscillator (Out) -> HPF (In)
HPF [High Pass]:
* Cutoff: 200 Hz


- HPF (Out) -> LPF (In)
LPF [Low Pass]:
* Cutoff: 2 kHz


- LPF (Out) -> Output (In)

Multi-voice

Section titled “Multi-voice”

Two voice strands running into a shared mixer → filter → output chain. The VOICE 1: / VOICE 2: markers tag each block’s voice field for post-processing — the layout and renderer itself treat every block identically.

VOICE 1:
- Osc1 (Out) -> Mixer (In1)
- Env1 (Out) >> VCA1 (CV)


VOICE 2:
- Osc2 (Out) -> Mixer (In2)
- Env2 (Out) >> VCA2 (CV)


- Mixer (Out) -> Filter (In)
- Filter (Out) -> Output (In)
