Roland SP-808ex Synthesizer Engine Overview & Demo

YouTube via stealthgear
"This is an overview of the SP-808ex synth fx engine where I play a few patches and talk about the synthesizer editing capabilities. I think the synth engine itself sounds very good and can add a special touch to your mix even when its only monosynth. When you are using the synth engine, make sure you have your midi controller set to ch. 11 and that effects are turned on. If the patch uses the d-beam, then turn on the appropriate button near the d-beam. Press FX INFO or Shift-FX Info to get into the editing features, and use the appropriate knobs for live tweaking.

The SP-808ex has something for everybody. Check out my tutorial on using its vocoder."

Rare BUCHLA 500 Modules

via this auction
"Extremly rare BUCHLA electric music box series 500 modules. ....only 3 exemplars ever made in the world!!! The cv interface module need of PSU and maybe the computer facilities directed to the series 500 computer system... I'm convinced that the joysticks and trigger, control voltages module can drive other modular systems with a right psu of course, they have a Cinch Jones plug for Power Supply and a pair of facilities connectors in the rear part. I don't know the right voltage that they need, I haven't any schematics.. I bought them for collection but ..I think they need of a new home with other Buchla brothers ;-) Amazing: the two devices!"
joysticks are photosensitive built with optoisolators ..so the sticks are luminescent...a primitive but charming
