XR22 VCO

VCO with AM Input and FSK (Frequency Shift Keying)

Analog oscillator with a very own approach and that is two independent frequency control circuits between which the VCO can switch autonomously. This alters both the sound and frequency ratios, created glitches and new wave forms. An AM input is used, depending on a pot's setting, as a extra audio input or a the modulation signal for the awesome ring-modulator.
Difficult to describe but very unique and interesting!

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

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

• LFO Mode

• Optional with Banana or 3,5mm Phone Sockets
