Pietro Grossing was a proto live coder. He got into electronic music in the 1960’s.
He wrote a program called dcmp that did music in real time. Tau2 was a 12 voice synthesiser which was computer controlled via an alphanumeric terminal doing code in real time. They had a telemetric concert that may predate the hub.
He ported his music languages to the Commodore 64 and adapted them for graphics.
These were uploaded to the internet with FLOSS licences.
Q: was this his day job?
A: he was an independent researcher at first, but then gained institutional support including building a synthesiser and technicians. In the 80’s, he returned to bring independent.
