Make Noise XPO Stereo Prismatic Oscillator


XPO is an all-analog stereo oscillator, borrowing ideas and features from the popular DPO and STO modules it offers clever approaches to synthesis, waveshaping, spatialization, and more! It's a single oscillator with multiple waveshaper pairs which can be used to create (instead of traditional panning techniques) stereophonic motion. 

For those familiar with the Make Noise QPAS stereo filter, the XPO is a great companion. 

The XPO is a great for those looking to patch complex timbres and explore unique means of spatialization.

The XPO or Stereo Prismatic Oscillator music synthesizer module is a Voltage Controlled Analog Oscillator designed for generating Sine waves, Triangle waves, Sawtooth and Spike waves, Sub-Octaves, Stereo Timbre Modulations (including Pulse Width Modulation and Wavefolding), Oscillator SYNC, Linear FM and more in the analog domain.

The XPO is designed to be the Stereo VCO complement to their Stereo Filter, the QPAS. The two modules share the core idea of complex circuits being controlled in multiple dimensions in the stereo field by a few powerful parameters. The Stereo Prismatic Oscillator also makes a particularly useful patch buddy for the STO, Mimeophon, and X-PAN.

 Make Noise XPO Features: 

  • Stereo Analog VCO with eleven simultaneous outputs (five mono outs and three stereo pairs)
  • Modulate Timbre via Stereo Pulse-Width Modulation, Stereo Vari-Timbre, and Stereo Wavefolding
  • Sine, Triangle, Sawtooth, Spike, and SUB mono outs
  • Unique Mono versions of all Stereo Waveforms via Left output normalizations
  • Modulate Left and Right channels together or separately thanks to normalization and attenuverters
  • Center parameter adds additional timbre control to both sides of Vari-Timbre and Wavefolded outputs
  • Linear FM Bus features voltage-control over FM depth and a normalization of SUB to FM input for easy GROWL
  • Hard SYNC circuit
  • Two 1v/oct inputs for transposition, melody stacking, or richest FM
  • Expo FM input with attenuverter
  • Designed to pair well with QPAS, Mimeophon, and X-PAN
