# Moog - Labyrinth Leads Mother-32 - Build Patch: [[Patches/Moog/Moog - Labyrinth Leads Mother-32]] Signal path: [[Patches/Moog/Moog - Labyrinth Leads Mother-32 - SignalPath|SignalPath]] An incremental build of that patch. One or two cables at a time, so you can hear each stage and watch the interesting voltages on the Mordax DATA. Starting points, jack names, and the final cable list come from the patch note. DATA jack names and modes come from the official [DATA User Guide](https://mordax.link/DATA_User_Guide) (SYS V. 01.02.05, updated 230310), linked from [mordax.net](https://www.mordax.net/products/data). **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 ## Before you start - Power the cases as usual. The DATA lives in **Eurorack 001 Installed** (BLACK panel, 16 HP), per [[Rack]] and [[Modules/DATA]]. The Moog 4-tier is four filled 60 HP rows, so the DATA will not seat in that case. Fly cables from the Moog patch bays to the DATA in the main rack, or sit the DATA next to the Moog. If flying cables isn't practical, treat every "Watch on DATA" step as optional and build by ear. The guide says its microSD card must stay in the slot during use. - All three rear 1/4″ outputs down at first, then into a mixer. - Set every module to the starting points in the [[Patches/Moog/Moog - Labyrinth Leads Mother-32|patch note]] before you add cables: Labyrinth SEQ1 on a minor or pentatonic scale (BIT SHIFT + BIT FLIP), SEQ1 CV RANGE 9 to 10 o'clock, LENGTH 7, SEQ2 LENGTH 5, CORRUPT on SEQ1 at 10 o'clock, EG TRIG MIX fully clockwise so its own voice speaks only on SEQ2's triggers, VCO FREQUENCY an octave above the Mother-32; Mother-32 sequencer stopped in KB mode, keys untouched, VCO WAVE SAW, CUTOFF 10 o'clock, RESONANCE 12 o'clock, VCF MOD AMOUNT 0, ATTACK fully counter-clockwise, DECAY 11 o'clock, SUSTAIN OFF, VCA MODE EG, a little GLIDE; DFAM a plain kick, snare and noise pattern over 8 steps (its own TEMPO is ignored on an external clock). - On the DATA, open the **Oscilloscope** program from the main menu. In each channel's pop-up menu, set **COUPL** to **DC**. The guide says you typically want to view signals as DC; AC coupling blocks a steady voltage and will make a clock or a stepped CV sit at 0 V or droop. Use trigger mode **AUTO** whenever the time scale is in the hundreds of milliseconds or in seconds. **DATA jacks, as named in the User Guide:** four **Input Jacks** (±10 V), four **Buffered Through Jacks**, and four **Output Jacks**. This build uses only the inputs and the throughs. The guide: "Regardless of the program running, a signal present at an Input Jack is buffered and sent back out of its corresponding Through Jack for use elsewhere in your patch." The official panel photo on mordax.net numbers those channels **1–4**; each Through Jack sits directly under its Input Jack, with a downward triangle between them. The panel does not silk-screen the words Input or Through; if your panel reads differently, check the panel. The Output Jacks (the right-hand bank, also numbered 1–4) are unused here. **Pass-through habit:** to watch a signal, unplug the destination end, go from the source into a DATA Input Jack, and continue from that channel's Buffered Through Jack to the destination. The cable color stays the color of the signal. The DATA has four channels, so they get reassigned as the build moves. A running plan is at the top of each step. ## 1. Hear the Mother-32 lead dry **DATA:** channel 1 can watch the Mother-32 VCA if you fly it over. Otherwise listen at the rear 1/4″ output. **Cables** 1. ⚫ Black · Listen at the Mother-32 rear 1/4″ output. **Set.** For this first listen, play the keys yourself, VCA MODE EG, short decay. Then stop the sequencer, leave it in KB mode, and take your hands off the keys before the next step. **Listen for.** A short, slightly gliding saw lead, still under your hand. **Watch on DATA.** Optional: Oscilloscope, TIME around 1MS, SCALE 5.0V, on the VCA output. A decaying saw on each key. **If it doesn't sound right.** Notes that never end: VCA MODE may be ON instead of EG, or SUSTAIN may be up. ## 2. Hand the lead to Labyrinth **DATA:** channel 2 SEQ1 CV (pitch), channel 3 SEQ1 TRIG. Flying these is optional. **Cables** 1. ⚪ Gray · Labyrinth SEQ1 CV (out, quantized, −5 to +5 V) -> DATA channel 2 Input Jack 2. ⚪ Gray · DATA channel 2 Buffered Through Jack -> Mother-32 VCO 1V/OCT (in) 3. 🔴 Red · Labyrinth SEQ1 TRIG (out, 0 to 5 V) -> DATA channel 3 Input Jack 4. 🔴 Red · DATA channel 3 Buffered Through Jack -> Mother-32 GATE (in, 0 to 5 V) **Set.** Labyrinth RUN. SEQ1 LENGTH 7, RANGE around 9 to 10 o'clock (the manual says about 9 o'clock is roughly an octave), CORRUPT low. Save a good one with BUFFER. The Labyrinth TRIG outputs are short triggers, so the Mother-32 note length comes from DECAY, not from gate length. **Listen for.** A wandering Mother-32 lead that stays in key and slowly mutates. Labyrinth's own sine-and-fold voice can already answer on its 5-step pattern if you have left its rear output in the mixer, an octave above. **Watch on DATA.** Channel 2, Oscilloscope or Voltage Monitor, TIME around 500MS to 1.0S, AUTO, SCALE 2.0V or 5.0V: a 7-step quantized staircase that occasionally changes. Channel 3, same window: short 0 to 5 V triggers, one per step, not a long gate. **If it doesn't sound right.** Notes stuck or out of key: SEQ1 may not be quantized to a scale, or a Mother-32 key may still be down. Notes so short they click: raise DECAY a little; you cannot lengthen them from the Labyrinth TRIG. ## 3. Move the filter, then clock DFAM **DATA:** channel 4 SEQ2 CV, and you can later move a channel onto Labyrinth CLOCK. **Cables** 1. 🔵 Blue · Labyrinth SEQ2 CV (out) -> DATA channel 4 Input Jack 2. 🔵 Blue · DATA channel 4 Buffered Through Jack -> Mother-32 VCF CUTOFF (in) 3. 🟢 Green · Labyrinth CLOCK (out, 0 to 5 V) -> DFAM ADV / CLOCK (in) 4. ⚫ Black · Listen at all three rear 1/4″ outputs on a mixer. To watch the clock as well, sit it on a freed channel (for example move off the Mother-32 audio watch): Labyrinth CLOCK -> DATA Input, Through -> DFAM ADV / CLOCK. **Set.** SEQ2 LENGTH 5, VCF MOD AMOUNT at 0 so this cable is the only cutoff motion. DFAM TEMPO is ignored on an external clock. Press DFAM RUN/STOP if it is not already running. **Listen for.** The lead's filter moves on a 5-step pattern. DFAM loops 8 steps under the 7-step lead, so the phrases slide past each other. Labyrinth's own voice answers on SEQ2's triggers. **Watch on DATA.** Channel 4, same slow window as the pitch: a 5-step CV, independent of the 7-step staircase on channel 2. If you add the clock, you should see a regular 0 to 5 V pulse driving DFAM. **If it doesn't sound right.** Filter pinned: lower SEQ2 CV RANGE. DFAM ignoring the grid: it may not have been started, or CLOCK may not be reaching ADV / CLOCK. All three phrases resetting together: check the lengths, which should be 7, 5 and 8. ## Full patch These are the cables from the patch note. If the DATA is still in the path, each watched signal is two cables (source to Input Jack, Buffered Through Jack to destination) instead of one. 1. ⚪ Gray · Labyrinth SEQ1 CV (out, quantized, −5 to +5 V) -> Mother-32 VCO 1V/OCT (in) 2. 🔴 Red · Labyrinth SEQ1 TRIG (out, 0 to 5 V) -> Mother-32 GATE (in, 0 to 5 V) 3. 🔵 Blue · Labyrinth SEQ2 CV (out) -> Mother-32 VCF CUTOFF (in) 4. 🟢 Green · Labyrinth CLOCK (out, 0 to 5 V) -> DFAM ADV / CLOCK (in) 5. ⚫ Black · Listen at all three rear 1/4″ outputs on a mixer. With the DATA left in as of step 3, the watched paths are: cable 1 through DATA channel 2, cable 2 through channel 3, and cable 3 through channel 4, with channel 1 free for the clock (cable 4) or a VCA output. Cable 5 is the rear-output listen. The DATA can stay in or come out. To remove it, patch each watched signal straight from source to destination, as in the list above. The sound should not change; you just lose the graphs. **What it should sound like, once the last cable is in:** a wandering Mother-32 lead that stays in key and slowly mutates. The Labyrinth's sine-and-fold voice answers on its own 5-step pattern. DFAM loops 8 steps under a 7-step lead, so the phrases slide past each other.
