We explored how to approximate Moog DFAM’s analog, continuously variable sequencer on other hardware and how these devices interoperate.
DFAM baseline
• DFAM’s pitch row is analog and stepless. You can tune “between” notes.
Arturia MiniBrute 2S
• The two Mod tracks output continuous CV (V/Oct).
• Patch Mod → DFAM VCO Pitch to get micro-intervals. Set a small range and attenuate for finer steps.
• To sequence the 2S itself steplessly, patch SEQ MOD → VCO 1 Pitch.
• The VCO Pitch jack breaks the internal pitch. To add micro-offsets while keeping base pitch, sum KBD CV + SEQ MOD in the 2S VCA (or an external mixer) → VCO Pitch.
• Alternative nudge: route SEQ MOD → VCO 1 FM for subtle bends (not V/Oct accurate).
Arturia MatrixBrute
• Use the Sequencer “Mod” lane as a source in the matrix.
• Route Seq Mod → VCO Pitch for wide continuous offsets, or Seq Mod → VCO Fine for precise micro-intervals.
• Per-step Slide and Glide smooth transitions.
Sequential Pro 3
• Assign a sequencer track as a modulation source.
• Route Seq Track → Osc Fine Freq with a small amount for near-stepless offsets.
• Enable Slew on that track for glide.
• Optional: alternate tunings for quantized microtonal steps.
Buchla vs Eurorack compatibility
• Different standards: ~1.2 V/oct, banana/Tini-Jax connectors, separate ground, higher pulse levels.
• Bridge with a format jumbler plus 1.2↔1 V/oct and gate/level translators.
• Eurorack-native “Buchla flavor”: Tiptop/Buchla 200t series.
Tiptop/Buchla 200t that feels DFAM-like
• 245t Sequential Voltage Source: per-stage continuous controls across multiple rows. Works as a stepless pitch sequencer when patched to an oscillator.
Takeaways
• You can approximate DFAM’s stepless workflow on MiniBrute 2S, MatrixBrute, and Pro 3 by routing a continuous sequencer lane to pitch or fine pitch and managing range/attenuation.
• For Buchla aesthetics in Eurorack without adapters, the 245t provides per-step continuous control similar in spirit to DFAM’s row.
