Pittsburgh Modular - GenXpander


Discontinued model, only one last unit in stock. Sales only as long as stock lasts.

As you can already guess by the name the GenXpander is an expansion module for Pittsburgh´s Generator module. It adds some waveshaping, individual outputs, enhanced internal FM and phase-inversion based timbral effects.



The GenXpander contains of four parts:

  • The waveshaper circuitry needs simultaneously a triangle and a square from one or two of genereator´s oscillators in order to generate a pulse and a sawtooth. Two switches select which VCO(s) provides the waveforms. If both waves come from the same oscillator then the result will be a clean sawtooth. If the waves come from different oscillators, an interesting waveform is created which can be modulated from sawtooth over triangle to square.
  • The Generator´s internal FM from GEN1 to GEN2 is pre-set to use the variable waveform for modulation. The FM wave switch of the expander allows for selecting the variable waveform or the triangle as modulator.
  • individual outputs for traingle and square waves of the Generator 1 and 2
  • BAD outputs: This section detects odd and even harmonics, can mix frequencies and waveshape the signals. This happens by inverting the triangle polarity depending on the frequency relation of both oscillators.
    -OE output: (odd/even): if the difference between the oscillators is an even number then triangle of first oscillator has normal polarity. If the differenc is even, the polarity is inverted.
    -DIF output: changes the polarity of second triangle in dependence of the frequency difference.
  • Waveshaper: Shape CV-Eingang, Puls- und Sägezahnausgang
  • Einzelausgänge für Dreieck und Rechteck von Generator 1 und 2
  • OE-Ausgang und Differenzausgang
