Moog DFAM (Drummer From Another Mother) Eurorack Cheat Sheet

Eurorack Specs

• Width: 60HP
• Max Depth: 26mm
• Power Draw: +12V (230mA max), -12V (Not used)
• Ribbon: 10-pin
• All signals: ±5V (10Vpp) Eurorack compatible

Quickstart

• Power On: No power switch; powered when adapter is connected or installed in rack.
• Warm-up: Allow a few minutes after power-on for oscillator/frequency stability.

Controls Overview

Knobs

• VCO 1 Frequency, VCO 2 Frequency: Set pitch of both oscillators
• VCO 1/2 EG Amount: Bipolar, amount of envelope to VCO pitch (-/center/+)
• VCO Decay: Envelope decay for VCO mod.
• VCO 1/2 Level: Mixer volume for each oscillator
• Noise/Ext Level: Level for noise generator or external input
• Filter Cutoff: Master cutoff frequency for filter
• Resonance: Filter resonance; self-oscillation in LP
• VCF EG Amount: Bipolar, amount of envelope to cutoff
• VCF Decay: Envelope decay for filter
• Noise/VCF Mod: Amount of noise (or CV) modulating filter cutoff
• VCA Decay: Overall output envelope decay

• Mixer Volume: Output gain

• 8x Pitch Knobs: Step pitches for sequencer

• 8x Velocity Knobs: Step velocity for sequencer

• Sequencer Tempo: Global tempo

Switches/Toggles

• VCO 1 Wave, VCO 2 Wave: Triangle / Square
• Hard Sync: Off/On (Osc 2 phase resets to Osc 1)
• Seq Pitch Mod: [VCO 1&2 / Off / VCO 2]
• Filter Mode: [Low Pass / High Pass]
• VCA EG: [Fast/Slow] (Envelope attack speed)

Buttons

• Run/Stop: Start/stop sequencer
• Advance: Manually advance sequencer (step)
• Trigger: Trigger selected step (no advance)

Patchbay Reference

All jacks: 3.5mm. Inputs: 0–+5V or ±5V, Outputs: ±5V (unless noted).
(Eurorack ±5V = 10Vpp modular standard)

Inputs

Outputs

Signal Path (Summary)

1. VCO 1 & VCO 2: Select tri/square waveform, tune frequency, hard sync, FM.
2. Mixer: Blend VCOs and/or Noise/External In.
3. VCF: HP/LP, cutoff, resonance, modulation (EG + Noise/CV).
4. VCA: EG-controlled amplitude, velocity and decay variation.
5. Sequencer: 8 steps, each with pitch & velocity; analog clock & patchable.

Tips & Tricks

• All EG amount knobs are bipolar (negative at left, neutral at center, positive at right).
• Set pitch modulation with SEQ PITCH MOD toggle.
• Use the patchbay to sequence or modulate ANY parameter via CV.
• Noise/EXT Jack can be replaced with external audio (removes noise).
• Filter self-oscillates in low-pass mode with high resonance; can be used as an additional tone source.
• Perfect for cross-modulation (“FM Toys” patch: VCO2 FM’ing filter cutoff!).
• Both Osc1 and Osc2 pitch can be externally controlled (1V/oct).
• Sequencer can act as CV or trigger source for other gear via patch outputs.
• Designed to immediately fit 60HP Eurorack systems.
• All inputs/outputs Eurorack voltages.

Troubleshooting

• No Sound?
• Check VCO FREQ, EG AMT, Filter cutoff/resonance, patch section for dead-end connections.
• Levels too low?
• EXT IN expects modular level (10Vpp). Amplify external line-level sources.
