"This listing is for a vintage Rev 4 Octave Plateau Voyetra Eight. Rev 4 is the most desirable and final revision that allows for a number of extra midi functions, most importantly aftertouch, pitch bending and modulation assignment. Rev 4 green boards are also robust and supposed to have more long-term reliability."

"A demo of the now discontinued Audiothingies P6. A cheap DIY VA-synth with a load of features, great sound and a small form factor. I use it a lot. It has some rolandish quality to its sound, at least I think so. The build took only 2 evenings."

This Is A Test: Dope Box prototype - crazy beat synthesizer thing
video upload by Mountainking Electronics
"This is the prototype for the Dope Box. It is designed around an obsolete ic that contains 15 different lo fi drum beats samples. The Dope Box contains a preamp that can be driven into distortion and a active LPF. It has rate controls to allow you to slow it down til all you hear is strange, stretched out digital bits or speed it up til it sounds like a skipping compact disc. In the right hands it has limitless creative possibilities.
I hope, at some point, to officially release the Dope Box but if and when I do it will be ultra limited edition as I only have 7 of the ics that the Dope Box is designed around. I am selling this prototype if anyone is interested. Please email me if you are interested in purchasing this prototype. [ at https://www.mountainkingelectronics.com]
Thank you,
Alan"
