"This is the original now obsolete module (osc-02 is different) fully working in very good cosmetic condition comes with cable for fitting to a doepfer power case... 3x voltage controlled oscillators in one module ! with seperate or pre mixed outputs and a ring modulation output of osc1 and osc2 !!!!!
all controllable by one cv input (1v/octave) or each voice has its own cv input (chords !)

This info is taken from the original web page now defunct

The OSC-01 Triple DCO provides you with three full-fledged analog oscillators under digital control in just one module. If desired, they can be played via one single control voltage for chords with fixed intervals. If you control the pitch of each DCO separately, for instance by a 3-row analog step sequencer, you can produce chords with changing intervals. The third oscillator features the extraordinary sawtooth waveform known from the first version SyLITE. Additionaly there´s a digital ring modulator.
Technical details

3 DCOs, that is analog oscillators with digitally controlled pitch (like in the Roland Juno 106), thus very stable. Each DCO has a CV-input (CV 1, 2, 3) for pitch, bu those are cascaded, so you can control all three oscillators with just one control voltage at CV input 1. The audio outs of the DCOs can be tapped at separate outputs or a common one. Furthermore puls width modulation, assignalble hard sync (os1 to 3 oder osc1+2 to osc3) and digital ring modulation of DCO 1 and 2 (internally switchable to 1 and 3) with a separate output. Three CV-inputs for frequency modulation (switchable to PWM) with a common attenuator for CV4 and an attenuator for CV6. DCO1 and 2: 16´, 8´, 4´, tune control, Waveforms: sawtooth, square, narrow pulse DCO3: 32´, 16´, 4´, tune control, Waveforms: square, narrow pulse, digital saw
inputs and outputs

cascaded inputs CV 1, 2 and 3 for FM. Inputs CV 4, 5 and 6 for FM or PWM (switchable), sync in, ring modulator output. Ausio out 1, 2 and 3 (cascaded)
