Behringer Analog VCO/VCF/VCA Module for Eurorack

This is the Behringer System 100 110 VCO/VCF/VCA Module. An authentic reproduction of the original "System 100M" circuitry from the 80s that can fit in a standard Eurorack case. The best part? Its at a very affordable price. Mix the 110 in with your existing rig or start your modular synth journey from here. Either way you're sure to have a lot of fun!

The 110 comes with a complete synth voice with an internally patched signal flow for ease of use and to save patching time so you can focus on your music. You can vary the VCO section by selecting one of three waveforms; triangle, ramp and Pulse Width Modulation which can be adjusted by the Mod Manual knob. The VCO also offers pitch and range control knobs as well as one audio output, which can be routed to another source, and two CV inputs.
