VCO with AM and FSK (Frequency Shift Keying)

The XR22 VCO FT is a modified version of the previous model XR22 VCO with a different manual frequency control.
Instead of the two ±2-octave switches and the two frequency knobs (ca 4-octave range), there are now two frequency knobs (ca 7-octave range) for coarse tuning and 2 fine tuning knobs. Further, the ‘Low F’ frequency range switch – which works for both FSK frequencies – is replaced by a 3-position shift switch with the settings ‘Lo’ (for LFO/ tremolo applications), ‘Mid’ (for bass sounds) and ‘Hi’ (for normal/high frequency sounds).

  • AM (Amplitude Modulation) Input
    Ring modulation
    CV controllable sine/triangle volume
    Advanced waveform generation with feedback

  • FSK (Frequency Shift Keying)
    Pulse and ramp generation
    Switching between two different frequency CVs
    Advanced waveform generating

  • LFO-, Bass-, High- Mode
  • Optional with Banana or 3,5mm Phone Sockets
