Jasper is a clone of the Wasp synthesizer that was made by the small British company EDP (Electronic Dream Plant) for a few years from 1978 to 1982. The Wasp was one of the first commercially available digital/analogue hybrid synthesizers. Designed by Chris Huggett and Adrian Wagner who created it as an affordable synthesizer using the then newly and widely available inexpensive CMOS digital logic chips.

I uploaded a demo of the synthesiser on youtube. It’s exactly the offered synthesizer but the video is showing a pre-version of the final casing.
