The PC contains a HardSID card which is controlled by a custom piece of software. The Yamaha V50 keyboard is plugged into the PC using MIDI and sends MIDI note on and note off messages. The Behringer BCR2000 control surface is also plugged into the PC using MIDI and sends MIDI controller change (CC) messages. The custom software receives both types of messages and writes SID chip register changes to the HardSID card.
The functions on the BCR2000 knobs and buttons are as follows:

Commodore 64 LIVE DEMO
Live demo of one of my songs.
Bassline is played by an good old C64 equipped with Cynthcart.
Tune is called “we ain’t finished yet” and has been featured on DEAD PIXELS long play.
In 2009 I began experimenting with SID chiptune (built-in sound generator chip of Commodore 64), and Cynthcart to create a blend of original 8bit sound from the 80’s and Rock music.

Analysing the Commodore 64 game music
Today music for computer games is taken just as serious as for a Hollywood film. Even in the early days of computer games when Commodore 64 ruled in the 1980s the music was important – but it sounded like nothing else….
Karen Collins has written an in-depth article on the music for the Commodore 64 games.
