After a long time of not being busy with real electronics due to the move of the whole orgnisation to the new building – it has a hugh impact – I slowly see more time for being busy with my core activities: make new instruments and electronics.
For one of our teachers, who owns a EMS Synthi A (see picture), I created a setup to be able to interface with the CompLex module.
A short quote from Wiki:
“The EMS Synthi A and the EMS Synthi AKS are portable modular made in England. The Synthi A model debuted in May 1971 and then Synthi AKS model appeared in March 1972 a with a built-in keyboard and sequencer. The EMS Synthi models are notable for its patch pin matrix and its functions and internal design”.

The Synthi A has a pin-matrix but also a 32-pin connector that is directly connected to the 16 ins and outs of the matrix (located directly under the pin-matrix). Instead of connecting the pins to the matrix, I created a first version of a connector that is directly connected to the CompLex matrix. So instead of placing the pins in the matrix we can change the setup with OSC and software!

I’m looking forward to the first test results!
