Description: This is the weird bit. Using the sound generators in a way they were not designed to be used produces some interesting sonic squawk and sideband modulation artefacts.

dès 3:28 j'ai pu obtenir cet effet sur un MS20 "trafiqué" (avec les sorties des VCO rajouté, un VCO routé vers l'autre, et/ou vers le VCF... https://soundcloud.com/fouxeu/sets/d-mo-mod-vco-out-1-2-pwm-in )

Hope you still have the RMI. seems to be pretty noisy, is it?

It is very possible this is the only recording of this rare synth demo on the planet!

Whilst restoring the ex Klaus Schulze GDS (originally used on  his 1980 Album, Dig It) back in 2014 I found a number of what appeared to be demo sequences on one of the 8 inch disks.  These may well have been supplied with the instrument by the Digital Keyboards sales team or just may have been for a demonstration at NAMM circa 1980.

I loaded up and recorded this one from the GDS which was a nice demonstration of the instrument's multi-timbral capabilites. 

Released in 1979, the GDS was a groundbreaking all digital instrument based on Hal Alles' Alles Machine at Bell Labs and featured 32 high speed digital oscillators implementing a mixture of FM and additive synthesis in 16-bit audio with two 16 stage loopable EGs per oscillator, velocity sensitive keyboard, multi-timbral playback and a built in sequencer!

The name of the demo is a mystery - at first I thought it might be a reference to Nyle Steiner but he didn't think there was a connection.

Maybe the NY in NYLE1 stands for New York?... who knows!
