Make Noise DPO Dual Voltage Controlled Oscillator Module

Description

Get Classic Analog Waveforms With The Make Noise DPO Dual Voltage Controlled Oscillator Module

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.

• Vintage voiced, all analog
• Triangle Core with Sine, Saw, Spike and 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
