Doepfer A-111-4

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.

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!

It's a pretty simple module; I mainly use it to create four polyphonic voices. I like that it also includes a summed output, which comes in handy when creating chord stabs. Additionally, you can prewire related modules—such as the A-105-4 and A-141-4—using jumper cables on the back. This is especially useful, as polyphonic patching can get quite wire-heavy. If you're looking for that kind of setup, it's worth noting that the internal connections are bypassed automatically when you insert a jack into one of the CV inputs.
