Roland's System-100m, which was built from 1979 to 1984, is probably one of the best-known modular systems. The manageable number of modules and especially the presence of several functions per module made it an attractive instrument for many a user. Behringer has transferred the classic dimensions to the compact Eurorack format and taken great care to ensure that sound and function are in no way inferior to the cult object.

The Behringer 110 VCO/VCF/VCA is a completely analog synthvoice and includes an oscillator a 24 dB lowpass filter and a VCA with logarithmic characteristic. The analog oscillator features triangle, sawtooth and square waveforms including pulse width modulation. Conveniently, the oscillator is equipped with an octave position switch, allowing the tone generator to be quickly adjusted in intervals. The filter is a resonant 24dB lowpass filter with the Roland-typical sound. The VCA is predestined for audio applications due to its logarithmic characteristic and also forms the end of the signal chain in the 110. The audio outputs are normalized respectively from oscillator to filter and from filter to VCA, but can also be used separately. In addition to the independent CV input for pulse width modulation, all three functions of the Behringer 110 VCO/VCF/VCA each have two control voltage inputs.
