It offers generous assortment of knobs for editing or tweaking the sound. At the time it may have been considered an alternative to the Minimoog or addition to a keyboard rig. The Kobol is a very versatile instrument. Offering many sought after features of other analog synthesizers of it's time. less than 200 of the Kobol were made and it remained in the synth market from 1978-1979.
