# Main - Shift Register Bells with Motor Mutation Case: **Eurorack 001 Installed** (main rack). Each module is used once. Source: original Jack labels from the disting mk4 User Manual v4.18 (F-6), the Rings, Shades and Beads manuals, the Mother-32 Users Manual, the Gieskes Reverse DC Motor manual, and ladik.eu (A-540). Signal path explained: [[Patches/Main - Shift Register Bells with Motor Mutation - SignalPath|SignalPath]] Incremental build: [[Patches/Main - Shift Register Bells with Motor Mutation - Build|Build]] ## Modules - Moog Mother-32: clock source (its own voice is optional) - Expert Sleepers Disting mk4 (#1): **F-6 Shift Register Random Quantized CVs** - Mutable Instruments Rings: the bells - Gieskes Reverse DC Motor: hand-spun mutation control - Mutable Instruments Shades: brake on the motor CV - Mutable Instruments Beads: reverb and space - Ladik A-540: stereo out **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. 🟢 Green · Mother-32 ASSIGN (out, sequencer clock) -> Disting #1 X (in, clock) 2. ⚪ Gray · Disting #1 A (out, quantized CV) -> Rings V/OCT (in, 3) 3. 🔴 Red · Disting #1 B (out, trigger) -> Rings STRUM (in, 2) 4. 🔵 Blue · Reverse DC Motor CV out (check panel; the v1 manual calls it "cv out") -> Shades channel 1 Signal input 5. 🔵 Blue · Shades channel 1 Signal output -> Disting #1 Z (CV in; summed with the Z knob) 6. 🟡 Yellow · Rings ODD (out) -> Beads IN L 7. 🟡 Yellow · Rings EVEN (out) -> Beads IN R 8. 🟡 Yellow · Beads L (out) -> A-540 channel A input 9. 🟡 Yellow · Beads R (out) -> A-540 channel B input ## Starting points - **Mother-32:** TEMPO slow, about 70 to 90 BPM. VOLUME down, or let it play a quiet low pattern from its own output. - **Disting #1 (F-6):** - Parameter 1 (Length) 8. Parameter 2 (Scale): pick a minor or pentatonic-type scale from the Quantizer list (2 = minor). - Parameter 3 (Output attenuverter) around 12 to 16 for a narrower range. Parameter 6 (Slew) 0. - Turn the Z knob up until the display flashes "**" (about +2 V). The loop is now locked. - **Shades channel 1:** attenuator mode, around 11 o'clock. - **Reverse DC Motor:** per the maker, spinning it right gives positive CV and left gives negative. Spin it left to pull Z back under +2 V and the register starts flipping bits, so the notes mutate. Let it stop, or spin it right, and the loop locks again. - **Rings:** sympathetic strings resonator, polyphony 4. STRUCTURE 12 o'clock, BRIGHTNESS 11 o'clock, DAMPING 1 o'clock, POSITION 10 o'clock. - **Beads:** DRY/WET 1 o'clock, REVERB 2 to 3 o'clock, SIZE 1 o'clock, DENSITY 1 o'clock, FEEDBACK 10 o'clock. ## Level notes - The v1 manual gives the motor CV out as 5 to 10 V peak-to-peak. Without Shades, one good spin throws Z well past the lock window. ## What it should sound like An 8-note bell and harp loop that repeats like a music box until you spin the motor. Spin it left and notes start changing; let go and the new loop holds. Wide, washy space from Beads.
