2hp VCO

Name: VCO
Brand: 2hp

Legendary CEM3340 analog oscillator in 2HP

2 HP Eurorack module

VCO is a compact 2HP analog voltage controlled oscillator built around the reissued Curtis CEM3340 IC, widely regarded as one of the finest-sounding analog oscillator chips ever made. It delivers simultaneous triangle, ramp, and pulse wave outputs with linear FM, hard sync, and PWM capabilities, covering over 10 octaves of musical range from subsonic drones to high-frequency tones.
