# Moog - Mother-32 Bass with DFAM Accents - Build Patch: [[Patches/Moog/Moog - Mother-32 Bass with DFAM Accents]] Signal path: [[Patches/Moog/Moog - Mother-32 Bass with DFAM Accents - 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. - Both rear 1/4″ outputs down at first, then into a mixer. - Set every module to the starting points in the [[Patches/Moog/Moog - Mother-32 Bass with DFAM Accents|patch note]] before you add cables: Mother-32 a 16-step bass pattern with a couple of accents and one glide, VCO WAVE PULSE, FREQUENCY low, CUTOFF 9 o'clock, RESONANCE 1 o'clock, VCF MOD AMOUNT 0, ATTACK fully counter-clockwise, DECAY 10 o'clock, SUSTAIN OFF, VCA MODE EG, VC MIX knob at 10 o'clock; DFAM kick on steps 1 and 5, noise-snare on 3 and 7, ghosts elsewhere, VELOCITY 1–8 set by ear. Press DFAM RUN/STOP before starting the Mother-32. Do not use a DFAM EG output in this patch; those run 0 to 8 V, outside MIX 2's range. - 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 bass and the drums on their own **DATA:** optional watches on each VCA output. Otherwise just listen at both rear 1/4″ outputs. **Cables** 1. ⚫ Black · Listen at the Mother-32 rear 1/4″ output. 2. ⚫ Black · Listen at the DFAM rear 1/4″ output. **Set.** Run each unit on its own for a moment so you know the pulse bass and the 8-step drum loop separately. Then stop them until the next step. **Listen for.** A punchy Moog pulse bass, cutoff low, short decay; and a simple analog drum loop, not yet locked or accenting the bass. **Watch on DATA.** Optional: Oscilloscope, TIME around 1MS to 10MS, SCALE 5.0V, on either output. **If it doesn't sound right.** Bass that never ends: VCA MODE may be ON, or SUSTAIN may be up. DFAM silent: RUN/STOP may be off. ## 2. Lock the clocks **DATA:** channel 1 watches Mother-32 ASSIGN. Flying this is optional. **Cables.** Press DFAM RUN/STOP first, then start the Mother-32. 1. 🟢 Green · Mother-32 ASSIGN (out; must be set to clock, which is the default) -> DATA channel 1 Input Jack 2. 🟢 Green · DATA channel 1 Buffered Through Jack -> DFAM ADV / CLOCK (in) **Set.** ASSIGN left at its default, the sequencer clock. **Listen for.** The 16-step bass and the 8-step drums now locked together, still without the filter accents. **Watch on DATA.** Channel 1, Oscilloscope, TIME around 200MS to 500MS, AUTO, SCALE 2.0V. Regular clock pulses. Other notes in this vault, citing the Mother-32 Users Manual, give ASSIGN's sequencer clock as 0 to +5 V. **If it doesn't sound right.** DFAM ignoring the Mother-32: ASSIGN may not be set to clock, or DFAM was not started first. If you skipped the DATA, patch this cable direct. ## 3. Open the filter on the loud drum steps **DATA:** channel 2 DFAM VELOCITY, channel 3 the VC MIX output going into cutoff. **Cables** 1. 🔵 Blue · DFAM VELOCITY (out, 0 to 5 V) -> DATA channel 2 Input Jack 2. 🔵 Blue · DATA channel 2 Buffered Through Jack -> Mother-32 MIX 2 (in, DC coupled, −5 to +5 V) 3. 🔵 Blue · Mother-32 VC MIX (out) -> DATA channel 3 Input Jack 4. 🔵 Blue · DATA channel 3 Buffered Through Jack -> Mother-32 VCF CUTOFF (in). The VC MIX knob is now the attenuator, as the manual describes. **Set.** VC MIX knob at 10 o'clock; turn it clockwise for more accent. VCF MOD AMOUNT stays at 0. DFAM VELOCITY is 0 to 5 V, inside MIX 2's −5 to +5 V. Do not swap in a DFAM EG output here: those run 0 to 8 V. **Listen for.** On the loud DFAM steps the bass filter jumps open, so the drums and bass accent together. **Watch on DATA.** Channels 2 and 3, Oscilloscope or Voltage Monitor, same TIME as the clock, AUTO, COUPL DC, SCALE 2.0V, POS 0.00V. Channel 2 steps 0 to 5 V with the velocity knobs. Channel 3 is that same pattern, smaller, after the VC MIX knob. They should line up with the loud drum hits. **If it doesn't sound right.** No accent: VC MIX may be fully down, or VELOCITY may not be reaching MIX 2. Filter pinned open: lower the VC MIX knob. Distorted or stuck cutoff: confirm you did not patch a DFAM EG (0 to 8 V) into MIX 2. ## 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. 🟢 Green · Mother-32 ASSIGN (out; must be set to clock, which is the default) -> DFAM ADV / CLOCK (in) 2. 🔵 Blue · DFAM VELOCITY (out, 0 to 5 V) -> Mother-32 MIX 2 (in, DC coupled, −5 to +5 V) 3. 🔵 Blue · Mother-32 VC MIX (out) -> Mother-32 VCF CUTOFF (in). The VC MIX knob is now the attenuator, as the manual describes. 4. ⚫ Black · Listen at both 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 1, cable 2 through channel 2, and cable 3 through channel 3. Cable 4 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 punchy Moog pulse bass locked to an analog drum loop. On the loud DFAM steps the bass filter jumps open, so the drums and bass accent together.
