A series of live improvisations and test recordings from two exceptionally rare 1979 Crumar General Development Systems (GDS) during final testing prior to shipping the beasts to their new owners following major restoration at Hideaway Studio. 

Considerably ahead of its time, and one of only four surviving examples, the GDS was a groundbreaking digital synthesizer featuring FM and additive synthesis in 16-bit audio.

The GDS was a ground breaking all digital 16-bit 32 oscillator FM / Additive synthesizer and was the direct precursor to the 1982 DK Synergy (sharing the identical High Speed Digital Oscillator and Factory Sound Library) both based on the Bell Labs "Alles Machine" from the late 1970s developed by Hal Alles and sharing some of the original design team members.  The synth was hosted by a large Z80 based IMS8000 computer and an ADDS Regent serial terminal with a green screen monitor running CP/M with dual 8" disk drives with mains powered spindle motors - dainty!

1979 Crumar General Development System (GDS) Demos

A test recording made with one of the world's rarest groundbreaking vintage digital synthesizers as it wakes for the first time in many years during major restoration.   The Crumar GDS was built in 1979 and was one of the first commercial all digital polyphonic synthesizers boasting 32 digital oscillators combining FM and Additive Synthesis.  This example was owned by a very famous German electronic musician and one of less than 10 ever built.

The restoration can be followed on my blog at VSE:

1979 General Development System: First Awakenings

A brief live improvisation I recorded using the first voice patch I managed to program into the 1979 Crumar GDS shortly after I undertook the major restoration (previously owned by the late Klaus Schulze) of this extremely rare groundbreaking early digital synthesizer.   It is named in memory of the late Max Mathews who played a major role in developing the software routines and concepts behind key parts of the GDS as well as in many other areas of pioneering computer based music technology.

1979 General Development System: The Max Factor

The first few seconds of audio to emerge from Brian Kehew's 1979 Crumar GDS after awakening for the first time during restoration of this extremely rare groundbreaking early digital synthesizer.    The GDS was extensively used by Wendy Carlos in the production of the soundtrack for the film Tron.

1979 General Development System: Brian's GDS Awakens

A live improvisation recorded on what was Klaus Schulze's ultra rare 1979 Crumas General Development System (GDS) [featured on Death of An Analog among others] during final testing prior to shipping the beast to its new owner following a 100% tear down and major restoration by D.A.Wilson at Hideaway Studio.  Considerably ahead of its time, and one of only three known surviving examples, the GDS was a groundbreaking digital synthesizer featuring FM and additive synthesis in 16-bit audio.

1979 General Development System: The Big Farewell

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!

1979 General Development System: Ultra Rare Original GDS Demo "NYLE1"

Whilst restoring the ex Klaus Schulze GDS (originally used on  his 1980 Album, Dig It) back in 2014 I made several test recordings throughout the project.

Here are some more excerpts from my test recording archives I recorded back in 2014.   The white noise at the beginning of the recording was some of the first audio that emerged from the beast on the first powerup during resurrection when the system crashed during an attempt to boot it!
