The A-110-1v Module is Doepfer's classic VCO, now with its Vintage Series panel. It contains all traditional analog waveshapes, Saw, Square (Pulse), Triangle and Sine, with individual outputs for each waveshape. It tracks faithfully with a 1v/oct input up to 8 octaves, and contains a range switch with 5 notches that jump by octaves. The Pulse Width of the square wave can be modulated with CV or controlled manually for timbral manipulations. It also contains a hard sync input for locking it to the frequency of another oscillator.
