Literal Brain Synthesizer

via CNN. Excerpt:
"An experimental system is letting a paralyzed man turn his thoughts into the beginnings of real-time speech, according to researchers...

Guenther said the electrode in Ramsey's brain was implanted four years ago. Its two-channel recording system only allows 20 to 40 neurons to control the voice synthesizer, but Guenther said newer, 32-channel systems, would allow over 100 neurons to be used.

'We're currently working on synthesizers that allow consonants to be produced relatively easily and we are also working on the hardware that would let us implant a 32-channel system in the next patient,' he told CNN.

'That should give us a dramatic improvement in the user's capability for producing sound, which will allow consonants to be produced, and then complete words.'

He added that it would probably be five to 10 years before the technology would be available to the general public."

Roland Jupiter-4 Analog Synthesizer

"vintage synth demo by RetroSound

Roland Jupiter-4
4-Voice Analog Synthesizer from the year 1978.
The JP-4 sound is very warm and organic. The 4 VCO`s are always a bit out of tune but this is the typical JP-4 sound. A very nice analog synth!
Unfortunately a bit underrated. Not compared to the bigger JP-6 or JP-8. For me the best sounded Jupiter.

the demo shows some sound settings, arpeggiator and unisono mode
FX: Lexicon MPX for delay and reverb

used by: Human League, Depeche Mode (Vince Clark), Tears for Fears, Duran Duran, Vangelis, Thomas Dolby...."
