This VCO uses a triangle-core design with high precision expo performance for excellent tuning accuracy, and the FM capabilities are a particular strength of this module.
Through-Zero Frequency-Modulation.
Wideband FM produces rich, inharmonic tones. Three switchable sensitivity settings offer everything from simple vibrato to complex tones.
Reversing Sync.
The direction of integration in the VCO core can be reversed on the rising, falling and rising & falling edges of a signal for ring-modulator-like effects.
VCO and LFO in a single module.
The frequency of the VCO can be reduced by a factor of 100 with a switch on the front panel.
The module is 14HP wide.
