This is the stripped down version of the Polymoog. It allows much less control. As you can see from the picture the whole right half of the control panel is blank. Presets are Vox Humana (some say this preset is the best of them all), String 1, String 2, Electric Piano, Piano, Honky Tonky, Clav, Harpsi, Brass, Chorus Brass, Pipe Organ, Rock Organ, Vibes, and Funk (a full 6 more presets than the Polymoog).
Controls available are: pitch adjustment for both VCO's, main volume as well as volume for all three keyboard sections, highpass filter amount, and highpass filter center frequency (from 60-300Hz), modulation rate and amount, and attack.
