This is the later revision with the 12V power input. It features a filter based on a CA3046 transistor array (5 very good matched transistors in a single 14 pin chip) as the Waldorf Pulse (and the Moog Voyager).
The earlier revision with the 9V power input uses a Curtis analog filter chip.
Both revisions do sound very different, but share the same features.
