# Main - Micro Sequence Acid Bass with Tape Echo Case: **Eurorack 001 Installed** (main rack). Each module is used once. Source: original Jack labels from the Mother-32 Users Manual, the Stages and Shades manuals, the disting mk4 User Manual v4.18 (D-2), and ladik.eu (A-540). Micro Sequence and A-180-1 jack names are from the maker pages; exact silk-screen: check panel. Signal path explained: [[Patches/Main - Micro Sequence Acid Bass with Tape Echo - SignalPath|SignalPath]] ## Modules - Pittsburgh Modular Micro Sequence: the 8-step line - Moog Mother-32: VCO, ladder filter, EG and VCA - Doepfer A-180-1: gate split - Mutable Instruments Stages: filter envelope (segments 5 and 6) - Mutable Instruments Shades: CV mixer for the filter - Expert Sleepers Disting mk4 Special Edition (#2): **D-2 Tape Delay** - 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. ⚪ Gray · Micro Sequence quantized pitch output (check panel) -> Mother-32 VCO 1V/OCT (in) 2. 🔴 Red · Micro Sequence Gate output (check panel) -> A-180-1 (any jack in one group; check panel for grouping) 3. 🔴 Red · A-180-1 -> Mother-32 GATE (in) 4. 🔴 Red · A-180-1 -> Stages GATE input of segment 5 5. 🔵 Blue · Stages output 5 -> Shades channel 2 Signal input 6. 🔵 Blue · Micro Sequence analog CV output (0 to 5 V; check panel) -> Shades channel 1 Signal input 7. 🔵 Blue · Shades channel 2 Signal output -> Mother-32 VCF CUTOFF (in). Leave channel 1's output empty, so this carries the slider CV plus the envelope. 8. 🟡 Yellow · Mother-32 VCA (out) -> Disting #2 X (in, audio) 9. 🟡 Yellow · Disting #2 A (out) -> A-540 channel A input 10. 🟡 Yellow · Disting #2 B (out) -> A-540 channel B input ## Starting points - **Micro Sequence:** Scale on Minor, length 8, Direction Forward. Tap in a tempo. Pull a couple of sliders to the bottom to mute those steps. The analog CV out still follows the slider, so a muted step still moves the filter. - **Mother-32:** - Leave the sequencer stopped in KB mode and don't touch the keys. The external pitch sums with the KB CV. - VCO WAVE on PULSE, PULSE WIDTH 11 o'clock. - CUTOFF 9 o'clock, RESONANCE 2 o'clock (the manual says above 3 o'clock self-oscillates), VCF MOD AMOUNT at 0. - ATTACK fully CCW, DECAY 10 o'clock, SUSTAIN OFF, VCA MODE EG. A touch of GLIDE. - **Stages:** segments 5 and 6 on RAMP. Segment 5 slider near the bottom for a snappy attack, segment 6 slider about a quarter up for a short decay. - **Shades:** both channels in attenuator mode. Channel 1 at 10 o'clock and channel 2 at 1 o'clock. - **Disting #2 (D-2):** parameter 3 (Output mode) 1, so A and B both carry the mix. Parameter 0 (Tape length) around 30, about 300 ms at 1x speed. Z (feedback) 10 o'clock. Nudge parameter 2 (Tape speed) for pitch-bent repeats. ## Level notes - Stages tops out at 8 V and the Micro Sequence CV at 5 V. VCF CUTOFF sweeps its full range on −5 to +5 V, so keep Shades below 2 o'clock or the filter pins open. ## What it should sound like A squelchy pulse-wave bass line. Each note gets a snappy filter blip, and the sliders set a per-step brightness under it. Mono tape echo repeats trail behind on both sides.
