Discrete Basic VCO Triangle-Core Oscillator

L-1 Basic VCO Triangle Core Oscillator

The Basic VCO, from L-1, is a triangle-core voltage-controlled oscillator for Eurorack modular synthesizer systems. It features separate outputs for Sine, Triangle, Saw, and Pulse waves, as well as inputs for 1V/Oct, FM, Reset Sync, and PWM. While it boasts a hefty range of 11 octaves in VCO mode, the module can also operate as an LFO at the flick of a switch.
