Patch Notes

0-Ctrl ─▶ XPO ─▶ Multigrain ─▶ [out]

0-Ctrl driving XPO — pitch and pressure from the 0-Ctrl sequencing the oscillator. XPO output into Multigrain for granular processing.

Three takes from a practice session. Maths in bouncing ball mode driving XPO, filtered through QPAS, recorded live into Morphagene, Erbe-Verb for reverb. Ultra-Kick as kick. Untitled 44, 0:00–3:10. Untitled 43, 0:00–2:40. Untitled 45, 0:00–3:30.

Patch Notes

Maths (bounce) ─▶ XPO MODULATE-L
               └─▶ XPO MODULATE-R

XPO (var sine) ─▶ QPAS RADIATE-L
               └─▶ QPAS RADIATE-R

XPO (saw) ─▶ QPAS IN ─▶ Morphagene (live rec) ─▶ Erbe-Verb ─▶ [out]

Maths Ch1 (unity out) ─▶ XPO FM
Maths Ch1 (unity out) ─▶ QPAS FREQ CV

Ultra-Kick ─▶ [kick drum]

Maths running in bouncing ball mode — driving XPO’s modulate inputs. XPO’s variable sine then feeds the QPAS radiate inputs, modulating the filter’s spatial spread. The saw wave is the main audio signal going into QPAS. Maths Ch1 unity out modulates both XPO FM and QPAS filter frequency. Out of QPAS into Morphagene for live recording, then Erbe-Verb for a touch of reverb. Ultra-Kick underneath as kick drum.

Two excerpts exploring DPO sine wave crossfading through ModDemix into QPAS and Mimeophon. Untitled 40, 0:00–1:05. Untitled 39, 1:40–2:40.

Patch Notes

DPO VCO A (Sine) ─┐
                   ├─▶ ModDemix ─▶ QPAS ─▶ Mimeophon
DPO VCO B (Sine) ─┘

Both oscillators running sine waves from the DPO — VCO A and VCO B fed into ModDemix, which blends and combines them before the signal moves on. Out of ModDemix into QPAS for filtering, then into Mimeophon for space and texture.

V/oct on the DPO is driven by Bard Quartet Arps, giving the pitch sequence its melodic character.

Clock & Modulation

Multimod runs as master clock in Red shape mode. It triggers Polimaths in Yellow (activate) mode. Tiny Rise and Fall handles envelope shaping with no rate and no oscillator engaged — acting as a pure slew/transient shaper on the modulation signals coming out of Polimaths.

Polimaths Routing (8 outputs)

Output	Destination
1	DPO — Fold input
2	QPAS — Volume + Freq 1
3–6	QXG — inputs
7–8	XPO — Left & Right Modulate

Audio Signal Flow

• DPO Square wave → QPAS (audio input)
• Spectraphon (all 4 outputs) → QXG (all 4 inputs)
• XPO Variable output → DXG (mix)
• QPAS Low Pass output → DXG
• QXG output → DXG

Drone Layer

The drone comes from Morphagene, loaded with a chord recorded in Ableton Live using Meld — voicing G2 / D3 / F3 with minimal LFO modulation applied before recording. From Morphagene the signal goes into Bruxa, with Multimod modulating Bruxa’s filter for subtle movement.
