Make Noise DPO / Dual Prismatic Oscillator
(Description via Make Noise)
The DPO is a voltage controlled oscillator designed for generating complex waveforms and implementing FM synthesis within
the analog domain. 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.
The DPO is also designed for fast live sound creation. The module groups functionality intuitively to make complex patching
move more quickly, while still interacting in an exciting way with all other modules.
Dynamic FM, Circular FM, Hard Sync and Additive Harmonic synthesis processes are all achieved with internal routing on the DPO.
The idea being that the artist will utilize patch cables to expand upon these standard concepts or interrupt them completely by
simply patching into the associated modulation destinations.
The DPO has two modulation buses, each with multiple destinations, the depth of which is adjustable per destination. The original
259 style modulation routing is split within the DPO into dedicated FM and Mod buses and switching jacks are utilized to create
internal routings that may be undone by patching an external signal to the CV inputs. The attenuator associated with the destination
CV input sets the final depth while the MOD and FM INDEX controls will act as the dynamic master depth controls.
Throughout the DPO optoisolators, commonly called Vactrols, are utilized as gain cells, and the result is that the module will have a
slow and organic response to control signals. This manifests itself in the smooth crossfading and phase reversal of the SHAPE
parameter, for example.
The DPO is a 100% analog, vintage voiced musical instrument and is not suitable for laboratory use.
» 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
