Dual variable-waveform VCO
The IF112 is a stable, wide-range 1V/Octave VCO with incredible sonic versatility. Two user-defined waveforms, each with a precisely stepped 6-octave range control that can also be externally voltage controlled.
Add to this, two unique, new types of sync, a funky digital ring-modulator type input, plus separate linear and exponential FM inputs.
