New Sputnik Modular VARIABLE WAVEFORM GENERATOR in stock: Buchla-style discrete analogue oscillator with ergonomic fader-based interface and circuit design by Andrew Morelli of Steady State Fate (SSF)

Sputnik Modular Matttech Modular 24.03.22

Sputnik Modular are back again! …this time with the VARIABLE WAVEFORM GENERATOR – a brand new, Buchla-style discrete analogue oscillator with an ergonomic interface featuring faders for the most important sound-sculpting functions. In stock now!

It offers 4 simultaneous waveform outputs – each of which has its own independent waveform processing (see further down for more details) – along with a pulse wave sub-oscillator which can be set to -1 or -2 octaves below the VCO’s fundamental pitch. There is an LFO switch for easily turning it into a complex modulation source, along with Coarse/ Fine Pitch controls, both Linear and Exponential FM (simultaneously) and a Hard Sync with a particularly “tearing” character.

As with the previous SPECTRAL PROCESSOR, this offers excellent build quality with solid bolted pots, high quality components and circuit design by Andrew Morelli of Steady State Fate (SSF)….not only that, but our man DivKid has already put together an in-depth video showing off all the timbral tastiness within this module. Enjoy! (video linked below)

This thing looks really special, and right up our alley.


AVAILABLE TO PURCHASE HERE!


The VARIABLE WAVEFORM GENERATOR features a host of parameters for shaping the sound – available to be tweaked manually from the front panel via sliders and/or modulated via CV. Each of these are applied to the relevant waveform and can be used simultaneously for an extremely complex, layered sound:

  • Pulse output – features PWM (Pulse Width Modulation) with a switch for Edge PWM (more traditional PWM) or Centre (which creates a stepped waveform and a more chorus-like effect.
  • Sine output – processed by a Wavefolder with Asymmetrical or Symmetrical folding, each of which produces a different tonal range.
  • Saw output – this offers a wave animator which morphs from a simple saw to either a Double or Triple peak waveform, for those Livewire AFG-style animations.
  • Triangle output – passses through a gorgeous Drive circuit with selectable Odd or Even harmonics for two different flavours of drive/ saturation which make for some wonderfully woody tones.

The CV inputs for these sound-shaping parameters respond to both positive and negative voltages at their CV inputs, which means that you can modulate the waves to silence and experiment with Amplitude Modulation (AM) for Pseudo-Ring Modulation tones.
