The Datanomics SYNTHI 100

This one is in via MATRIXSYNTH reader, Daniel Araya of Camp303 who also restored the Belgrade SYNTHI 100 featured here.

"I just restored the University of Cuenca Synthi 100!

This is the last S100 ever made, by the company Datanomics that took over EMS in 1979.

They produced this unit in 1981/82 and it was used at Gabinete de Música Electroacústica de Cuenca (G.M.E.) until it was put in storage for many years.

Now, thanks to professors Sylvia Molina Muro and Julio Sanz Vázquez a new G.M.E. is started and the Synthi 100 is restored to be used at the University.

The Synthi had been stored in a good environment and was in a nice state.

This machine is very different from the other S100's, it is completely redesigned internally by Datanomics and is using CEM chips (Curtis Electromusic Specialities) that made it a lot simpler to service because the reduced number of components.

The sequencer and keyboard are based around Z80 microcontrollers and are greatly improved from the old ones. Some components had not aged well so I changed out every power supply capacitor and replaced some broken IC's and went through all modules and functions.

I managed to fix about 97% of it in two days, a small part of the sequencer and some controls are still left for the next visit.

The new studios are modern and spacious and sports an amazing vintage quadrophonic Genelec 1024B sound system that is also being restored as well as some cool vintage outboard effects and various reel to reel tape recorders.

I also discovered an original ad/article for this synth while researching, check this out.
