    Make Noise to be the fault of the user are not covered by this warranty, and normal service rates will apply. During the warranty period, any defective products will be repaired or replaced, at the option of Make Noise, on a return-to-Make Noise basis with the customer paying the transit cost to Make Noise.

    Eurorack style bus board, minding the polarity so that the RED stripe on the cable is oriented to the NEGATIVE 12 Volt line on both the module and the bus board. On the Make Noise 6U or 3U Busboard, the negative 12 Volt line is indicated by the white stripe.
  • Page 5: Overview

    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.

Follow Attenuator: determines how well VCO A Follows VCO B. With nothing patched to Follow CV Input works as standard panel control.

    80%. The FM overdrive combined with the Bi-Directional Dynamic FM results in some extreme Cross Modulation capabilities. These sounds get out of hand quickly. The key to controlled FM within the DPO is attenuation since setting the Index to 100% really does push the circuit to its limits.
  • Page 10: Vco B Behavior

    VCO B. It is useful for chaining together multiple DPOs (or DPO and other VCO) for more complex FM, chords and other patches where tuning errors need to be minimized.
  • Page 11: Mod Bus And Timbre Shaping

    MOD BUS and Timbre Shaping Sections: Mod Bus The internal Mod Bus Source is hardwired for VCO A Sine wave, with the power to use any external source by patching to the EXT. Source Input. The internal Mod bus system makes use of the Normalization Switch found on the mini-jacks, so with nothing patched to the Shape, Angle, and Fold CV inputs the associated attenuator sets the nal amount of modulation applied to the destination.
  • Page 12 MOD BUS and Timbre Shaping Sections: (cont’d) The phase reversal and Amplitude Modulation that occurs around the 12:00 range of the Shape parameter value is useful on it’s own (before Folding occurs) for subtle and pleasing modulations via LFO. The Shape circuit is slow and smooth with a unique response quite unlike the typical balanced modulator or VCA.

    Attenuators to 12:00. Set Fold to 9:00 and set Fold CV attenuator to 12:00. Set Mod Bus panel control to 12:00. Patch Gate from sequencer or CV KB to Strike Input of DPO. Push button to select LFO behavior at VCO A. Set VCO A Freq. to around 9:00 and set Follow to full clockwise (100%).
  • Page 15 Monitor Final output. Turn Folds and Shape to 0 (full CCW). Turn Shape and Fold CV input attenuators to 12:00. Patch Pressure Points common Gate out to Strike input, Pressure Points tuned voltage B or C to DPO VCO B 1V/Oct, and Pressure Points common Pressure out to Mod Bus External Source Input.
  • Page 16 Patch Ideas: Wobble Bass: Monitor Final output. Adjust Fold, Angle, Shape panel controls and input attenuators to 12:00. Set VCO A to LFO mode with coarse Freq ~9:00. Adjust Mod Bus Index Panel control full CW, and FM Bus Index panel control full CCW. Adjust Follow panel control full CW.
