AQA Elektrix UP73R-VCO

Ramp-core based VCO with simultaneous rising/falling sawtooth, triangle, sine and pulse waveforms. This is a very good sounding VCO. The oscillator core is a ramp wave, the VCO generates five waves simultaneously, features linear FM, three selectable frequency ranges and a ten-turn potentiometer for super exact tuning. A highlight of this oscillator module is the flexible sync. A very unusual feature is the possibility to set the synchronisation Threshold, allowing for a smooth transition from no sync over soft sync to hard sync which generates really extraordinary harmonic structures. Surprisingly this parameter is voltage controllable and the input is even equipped with a polarizer. The combination of simultaneous modulation of pulse width and sync threshold brings forth very interesting results which you certainly haven’t heard before.
