This is an all analog synthesizer module used to create new timbres and waveforms with your existing VCOs. It uses a CD4046 phase locked loop chip in combination with a binary counter to multiply the frequency of the input signal. It then has 7 outputs divided down from that multiplied frequency which are mixed together. It's simple to use and has a distinct sound.
