Four useful VCOs packed in a small format. It can give four good monophonic voices, but can also be the heart of a polyphonic system. Great sound, grear quality. Thanks Doepfer!

Four simple VCOs in one module

Each VCO can be frequency modulated and has a triangle, saw and pulse output.

The master section can combine all VCOs into one output, again with a choice of the three waveforms. This is useful to build a paraphonic voice. The tuning of the master section will affect all oscillators.

Hint: check the manual for jumper configuration to configure hard / soft sync and PWM.
