The DPO is Make Noise's flagship complex oscillator — a West Coast synthesis powerhouse with deep FM, cross-modulation, and waveform shaping built in. Gently used, excellent condition, fully functional.What it is:The DPO is modeled after the classic Buchla Model 259 Dual Oscillator, carrying the tradition of early West Coast synthesis into Eurorack format. Both VCOs are operable as primary signal sources — it's a Dual Primary Oscillator in the truest sense — organized to easily modulate and cross-modulate between the two oscillators without patch cables, yielding complex timbre without the wire spaghetti.VCO A:Triangle core with Sine, Saw, Spike, and Square outputsHard Sync circuit — combined with Dynamic FM yields complex, evolving timbresOperates as LFO for slow morphing of VCO BVCO B:Triangle core with Sine, Saw, Spike, and Square outputs3-parameter waveform shaping with Dynamic FMShape, Fold, and Modulation controls for complex timbral variationModulation Architecture:Internal FM Bus and Mod Bus with dedicated CV attenuatorsBi-directional Dynamic FM Bus — circular FM between both oscillatorsMod Bus accepts external source via EXT input (replaces VCO 1 Sine)Both oscillators have 1V/Oct, linear FM, and exponential FM inputsNormal, Lock, Sync, and LFO modes28HP / Eurorack format — 70mA ±12VCondition: Gently used. Excellent cosmetic and functional condition. No rack rash on panel or knobs. Original knobs will be included in ship.Why it's worth it: The DPO is one of the only modules that gives you a complete West Coast complex oscillator system in a single module. Buchla-inspired FM architecture with full Eurorack integration.Ships carefully packed via UPS with tracking and insurance from Los Angeles, CA. Kept in temperature controlled, smoke free and pet conscientious studio environment.
