Rare Kurzweil VA1 Demo

Kurzweil VA1 Quick Demo 1 by WeiserSound

Demo of the suepr rare Kurzweil VA1 that enver made it into production. Apparently the engine made it's way into the PC3X.

"I finally dusted off my VA1 and banged out a very quick/dirty demo with 9 tracks, one take each, no quantization, plus a cheesy drum track. The display closeup shows choices for oscillators, filters, "deform" (an extra block of shapers and distortions), "processors" (sub oscillators, ring mod, etc in the Osc section), modulation sources and FX (not implemented).

There's a tiny bit of reverb con everything, and a small amount of Laserverb on two of the leads, both coming from a KSP8. Most of the better DSP items survived and now live inside of the current Kurz boards like PC4, Forte and SP6. Note - many of the DSP items were experimental or iterations, never meant to see the light of day.

This is one of ten prototype units that were made, and one of the few that had the cooler paint job.

For music choice, I went with The Traitor, from Herbie Hancock's Manchild album, an old fav!"

You can find a handful of posts featuring the Kurzweil VA1 here.


  1. It has a joystick. Must be an Axel Hartmann design.

  2. In the rear corner view the VA-1 resembles a tarted up Novation KS.
