"Two identic very warm and phat oscillators which recalls the Oberheim Xpander and Minimoog Voyager (with filter fully open). The internal pre-patched frequency modulation is also very nice, just turn the control and enjoy the brilliant sound without patching.

The circuit is identical to the first VCO of the Cwejman S1 so you can use the module as an LFO, too. Additionally there´s a pre-patched hi-quality ring modulator which you can also use with externals signals of course. Each VCO has a positive and inverted output which provides only one waveform at the same time but 7 different waveforms are available, three of which (!) feature pulse width modulation. Penko´s tipp: Set both VCOs to pulse or mixed-pulse and make only the 2nd VCO audible. Then slowly turn up the FM-Level control on VCO2 and play with the PWM controls... that´s fun. Depending on the setting of frequencies or intervals very expressive sounds can occur. This new version now features switchable internal pitch-CV connection via the buss. Generally all Cwejman modules are shielded from interferences and contain lots of calibration possibilities on the backside, see picture."
