EMS Synthi 100

   0 reviews  -  1912 views

    Formerly known as the Digitana and aka The Delaware, the EMS Synthi 100 used the same technology as the VCS3, but built into a very large console patched with two 60 x 60 matrix boards, one for the signals and one for control voltages. Only 40 built. Sold mainly to Universities and radio stations, the most famous and overworked model belonged to the BBC Radiophonic Workshop and was the main synthesizer used throughout the 70s.

    Several of the devices were packaged separately as small wooden sleeved units listed below:

    Pitch to Voltage Converter
    Triple Slew Limiter
    Eight Octave Filter Bank
    Two-Voltage Random Generator

    Designer Peter Eastty designed a computer as an add-on to the Synthi 100 interfaced to the control matrix board via two 24 x 60 matrix boards.

    It included:

    PDP8/M with 4K RAM
