Both envelopes work independently but can be triggered over Gate Input 1 with Gate 2 unpatched. The unit also offers Gate-Inputs from the system-bus allowing you to trigger the envelopes from an appropriate MIDI/CV-interface without front patching.
Typically, both envelopes work with logarithmic characteristics. However, a switch allows to change the character of one selectable envelope to linear.
Both envelopes offer two parallel outputs each. In many case this makes the use of multiples superfluous.
The module has a width of 60 mm (12 TE).
Both LFOs offer individual inputs to reset the waveform, making it possible to synchronize to a sequencer with appropriate rate settings and separate reset-impulses.
LFO 1 offers triangle, saw tooth down and square waveforms, LFO 2 offers triangle, saw tooth up and sample & Hold. Output voltages are +/- 5 volts at maximum.
When not patched, the two CV-inputs are internally cross-wired, meaning that LFO 1 controls the speed of LFO 2 and vice versa with both attenuators being active to set modulation intensity.
The module has a width of 40mm (8 TE).
OSC-03 offers a variety of notable functions: Beside a common CV-control voltage for all VCOs, all oscillators can be individually controlled by CV-sources, e.g. by different tracks of a CV-sequencer like Doepfers MAQ-16/3 or the AS Oberkorn. VCO 1 can be synchronized to VCO 3, individually or paired with VCO 2. The same goes for external hard-sync. The additional CV-inputs allow for common and individual modulations.
Three outputs allow for summed and individual audio outputs. A separate outputs carries a digital ring-modulated signal of OSC 1 and 2 (configurable to OSC 1-3 by jumper).
The difference between OSC-02 and 03 is, that the OSC-03 has a digital noisegenerator and an audiomixer.
The module has a width of 80mm (21 TE).
