The DPO music synthesizer module is a dual Voltage Controlled Oscillator designed for generating complex waveforms. Expanding on the classic arrangement of Primary and Modulator Oscillators, the DPO has both of the VCOs operable as complex signal sources. It is in essence a Dual Primary Oscillator.

FEATURES

• Vintage voiced, all analog
• Triangle Core with Sine, Saw, Spike & Square wave shapes
• Dedicated FM and Mod buses
• Modulation source signals are internally routed with associated destination CV attenuators setting final depths
• Mod Bus has added capability of using external source (patched at EXT. SouRCe input) in place of VCO 1 Sine
• Bi-Directional Dynamic FM Bus allows for circular FM
• VCO A features Hard Sync circuit which combined Dynamic FM yields complex sounds
• VCO A operates as LFO, perfect for slow morphing of VCO B timbres
• VCO B features complex timbral control through the use of a 3 parameter waveform shaping and Dynamic FM
• Utilizes Vactrols
• Pairs well with the Echophon

The Make Noise DPO (Dual Prismatic Oscillator) is a complex, all-analog Eurorack synthesizer module. Inspired by the Buchla 259, it acts as a dual voltage-controlled oscillator (VCO) with internal FM and West Coast-style wave shaping

Core Specifications

• Module Size: 28 HP width
• Depth: 30mm
• Power Draw: 70 mA at +12V, 70 mA at -12V, and 0 mA at +5V [1, 2, 3, 4]

Key Features

• Oscillator A (Modulation): Features a triangle core with triangle, saw, and sine wave outputs. It has four operating modes (Normal, Lock/Phase Sync, Sync, and LFO). [1, 2, 3, 4]
• Oscillator B (Carrier): Features complex timbral controls using 3 parameter waveshaping (Shape, Angle, and Fold). [1, 2]
• Built-in Modulation Buses: Includes dedicated FM and Mod buses for internal routing, allowing users to achieve dynamic FM, circular FM, and hard sync without patching external cables. [1, 2, 3, 4, 5]
• Vactrols: Utilizes Vactrols globally as gain cells, giving it an organic, vintage-voiced response. [1]
• Strike Input: Allows users to send percussive, audio-rate impulses to the wave folder to create plucky, drum-like timbres. [1, 2]
