Radical technologies spectralis synthesizer

YouTube via vaskuryandex.

"The Spectralis is the first "GrooveBox", which combines the LIVE usability of the latest digital technology with the best elements of proven analog technology. We also have thrown in some other cool features which give the synthesizer much more flexibility than anything seen before. While traditional Sequencers are limited to playing back rhythm patterns and tone sequences, the step Sequencer of the SPECTRALIS makes possible highly complex sound creations which opens up completely new worlds of sound when used in connection with the programmable FIXED FILTER BANK. In addition to its outstanding analog sound possibilities the SPECTRALIS also provides DSP based sound creation, which takes care of all the ancillary needs for drumsounds and polyphonic voices. This sound creation is 48 voice and offers killer drum sounds, creamy pads and a lot of other goodies"

The Hartmann Hohner Adam

via sequencer.de. You can find more info on this synth on the Hohner ADAM page on sequencer.de. BTW, Moogulator recently added a number of items to the synth db on sequencer.de. You can see the full list here.

Update via swissdoc via the comments:
"More details here. Stefan Stenzel from Waldorf wrote the software for the ADAM."

Moog synthesizer collaborator Herbert Deutsch at IMAC

"One of the most radical shifts in music began in 1961 with a hobbyist magazine article on how to build a theremin and a jazz musician from Baldwin named Herbert Deutsch.

The theremin, an electronic device that generates sound using radio frequencies, had been around for a while, but Deutsch found the Electronics World article interesting enough to pick up the issue and follow the instructions. When he couldn't get his gizmo to work, he phoned the article's author, an engineer, who gladly mailed out an easy-to-assemble kit for $49.95.

Two years later, Deutsch spotted the engineer selling his kits at a music trade show upstate in Rochester, and the two fell into conversation. They discussed a relatively recent invention called the Mark II synthesizer, which made music by sucking up rolls of key-punched paper and etching the results with a lathe onto a shellac record. It was intriguing, but you couldn't exactly 'play' the thing like a piano or guitar, or even a theremin.

'Wouldn't it be exciting,' Deutsch told the engineer, if there were smaller synthesizers 'that a performer could own, or a composer could own? Something you could have in your home?'"

The engineer? Bob Moog of course. Title link takes you to the full article.
