"A Custom Circuit-Bent Yamaha HandySound HS-200. A small, portable keyboard from the early 80s. This bent instrument was used to create the PortaSynth sample instrument by Icebreaker Audio.
More information on the original can be found here
Bends include 3 knobs:
Audio feedback
Filter Cutoff
Glitchy Thing
As well as a speaker on/off switch and a mono jack output, so you can use a DI signal and the built-in speaker at the same time. In order to fit in the new electronics, the original speaker was replaced with a smaller one. Other than the speaker, all original parts function as normal. Takes 5 AA size batteries, or a 9-12V DC power in (not included)
Selling to US, Canada and Europe."
