New Prototype Befaco VCO III

via Befaco where you'll find more info in Spanish.

Googlish:
"We finished the prototype of our new VCO. The idea was to make a compact version of the above oscillator, which occupied the space of a single module (the II was two-fold), and was cheaper and easier to build.

We love was enough. Basically, the only function that we had to step down was the mixing section, where it was possible to combine the desired waveform at different volumes. Another thing is that it fails to reach frequencies as low as II, which can easily be used as LFO.

Instead, it has integrated a sub oscillator, which can run one, two or three octaves below the main frequency and a 10-turn potentiometer (!) To control the pitch.

Soon to be available for production in the workshops."
