# Crossover - Subharmonicon Plays the Seahorse Cases: **Synthrotek SeaHorse** + **Moog 4-tier**. Each physical module is used once. Source: original Jack labels from the Subharmonicon User Guide, the Plaits, Rings and Shades manuals, the disting mk4 User Manual v4.18 (L-2), and the Ladik A-541 description on ModularGrid. Signal path explained: [[Patches/Crossover - Subharmonicon Plays the Seahorse - SignalPath|SignalPath]] ## Modules - Moog Subharmonicon (Moog 4-tier): sequencers, rhythm triggers, its own drone - Mutable Instruments Plaits (SeaHorse): plucked inharmonic string - Mutable Instruments Rings (SeaHorse): second string line - Mutable Instruments Shades (SeaHorse): 2-into-1 mix - Expert Sleepers Disting mk4 (SeaHorse): **L-2 Mono-to-Stereo Reverb** - Ladik A-541 (SeaHorse), or the Mini Speakers **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 ## Cables 1. ⚪ Gray · Subharmonicon SEQ 1 (out, −5 to +5 V) -> Plaits V/OCT (in, 5) 2. 🔴 Red · Subharmonicon TRIGGER (out, 0 to 5 V, 1 ms) -> Plaits TRIG (in, 3) 3. ⚪ Gray · Subharmonicon SEQ 2 (out) -> Rings V/OCT (in, 3) 4. 🔴 Red · Subharmonicon SEQ 2 CLK (out, 0 to 5 V) -> Rings STRUM (in, 2) 5. 🟡 Yellow · Plaits OUT (out, 6) -> Shades channel 1 Signal input 6. 🟡 Yellow · Rings ODD (out) -> Shades channel 2 Signal input 7. 🟡 Yellow · Shades channel 2 Signal output (channels 1 + 2; leave channel 1's output empty) -> Disting X (in) 8. 🟡 Yellow · Disting A (out) -> A-541 channel A input (1/8″) 9. 🟡 Yellow · Disting B (out) -> A-541 channel B input (1/8″) 10. ⚫ Black · The Subharmonicon's own sound comes from its rear 1/4″ output. ## Starting points - **Subharmonicon:** - QUANTIZE 8-ET (diatonic), SEQ OCT ±1. - RHYTHM 1 to 2, RHYTHM 2 to 3, RHYTHM 3 to 4, RHYTHM 4 to 6. Assign 1 and 3 to SEQ 1, and 2 and 4 to SEQ 2. TEMPO 11 o'clock. - Mixer LEVELs low (around 10 o'clock) so it's a bed under the strings. - The SEQ jacks carry only the step offsets, so set each voice's root with the Plaits and Rings FREQUENCY knobs. - **Plaits:** second bank, fourth model (inharmonic string). HARMONICS 10 o'clock, TIMBRE 12 o'clock, MORPH (decay) 1 o'clock. TIMBRE, FM and MORPH attenuverters at 12 o'clock. - **Rings:** string resonator, polyphony 2, FREQUENCY an octave above Plaits. STRUCTURE 12 o'clock, BRIGHTNESS 12 o'clock, DAMPING 12 o'clock. - **Shades:** attenuator mode, channel 1 at 1 o'clock and channel 2 at 12 o'clock. - **Disting (L-2):** Z positive about a third, parameter 0 (Size) 20, parameter 1 (Feedback) 24 (the default). ## Level notes - All signals are within spec: SEQ outs are ±5 V, and the CLK and TRIGGER outs are 0 to 5 V pulses. Plaits TRIG and Rings STRUM read them fine. - The cases run on separate supplies. If you get hum when you join them, look at grounding before blaming the patch. ## What it should sound like Two plucked-string lines in a diatonic scale, played in Subharmonicon polyrhythm: Plaits on SEQ 1's 2-and-4 grid, Rings on SEQ 2's 3-and-6. The Subharmonicon drone sits low underneath, all in a stereo room.
