Anyhow music was produced using software on either machine called a 'tracker'. A popular program for the Amiga was Octomed, a quick search on google will will bring up various results! On the Amiga this kind of music was know as a 'mod'. A *.mod file contains a set of instruments in the form of samples, a number of patterns indicating how and when the samples are to be played, and a list of what patterns to play in what order. There were other varients such *.xt, sm3,
Have a look at some of the links below!
1. Google results for amiga music
