The Moog Mother-32 offers a complete VCO-VCF-VCA synth voice in a single Eurorack module.

While the Mother-32’s default internal patching lets it be easily used as a monophonic synth, the synth’s extensive patching options also make it possible to use it paraphonically.

Paraphonic synths offer the ability to play different notes simultaneously, but do not offer a complete synth voice for each note. For example, a paraphonic synth might offer two oscillators, with separate control of each oscillator’s pitch, but route the output of the two oscillators through a single VCF-VCA audio path.

This video, via loopop, demonstrates how to use the Mother-32 paraphonically, using its ‘hidden’ oscillators, the resonant filter and the LFO.
