# Moog - DFAM on Subharmonicon Polyrhythms - SignalPath Patch: [[Patches/Moog - DFAM on Subharmonicon Polyrhythms]] ## Overview The Subharmonicon clocks the DFAM and fires its envelopes on rhythm hits. The DFAM's velocity and pitch talk back into the Subharmonicon bass. Listen at both rear outputs. ```mermaid flowchart LR Sub[Subharmonicon] -- "CLOCK" --> DF[DFAM drums] Sub -- "TRIGGER" --> DF DF -- "VELOCITY" --> Sub DF -- "PITCH" --> Sub Sub --> Mix[mixer] DF --> Mix linkStyle 0 stroke:#2a9d3a,stroke-width:3px linkStyle 1 stroke:#d62828,stroke-width:3px linkStyle 2 stroke:#1e63d6,stroke-width:3px linkStyle 3 stroke:#1e63d6,stroke-width:3px linkStyle 4 stroke:#222,stroke-width:3px linkStyle 5 stroke:#222,stroke-width:3px ``` **Cable colors:** [[Cable Colors]] after [Learning Modular](https://learningmodular.com/choosing-patch-cables/): ⚪ Gray 1 V/oct · 🔵 Blue modulation · 🟡 Yellow audio · 🔴 Red gates/triggers · 🟢 Green clock/sync · ⚫ Black external ## Why the loop never lines up the same way twice Subharmonicon CLOCK, 0 to 10 V, goes to DFAM ADV / CLOCK, which the DFAM guide rates +10 V tolerant, so the DFAM steps still advance on that clock. Subharmonicon TRIGGER goes to DFAM TRIGGER, which breaks the TRIGGER input's normal from the sequencer clock, so the DFAM envelopes now fire on the Subharmonicon rhythm hits instead of on every step. Rhythms 1, 3, 4 and 5 share two sequencers, so the hits land on a 1-3-4-5 grid instead of straight eighths. Press DFAM RUN/STOP first, then PLAY on the Subharmonicon; the DFAM guide says to start the clocked unit first. ## Why the bass moves with the drums DFAM VELOCITY goes to Subharmonicon VCO 2 SUB, so the VELOCITY 1–8 knobs also pick VCO 2's subharmonic. DFAM PITCH goes to Subharmonicon CUTOFF, so each drum step also moves the bass filter. Neither destination is a 1 V/oct pitch jack, which is why both cables are blue (judgment calls in the patch note). The Subharmonicon's own EG is on, with a short attack and a modest decay, VCO 1 low for bass. ## Short version The Subharmonicon is the grid, the DFAM is the kit, and they keep borrowing each other's accents.
