Custom music trackers? You've got to be joking. I never got custom anything. I used Protracker. I can't recall any custom tools at all. Psygnosis was pretty stingy. Programmer time for audio? I don't think so. Me and Tim Wright had to bring our own music gear into work because they wouldn't buy us any music gear. Then we got broken into and it all got stolen.
"Why did you have your own equipment in work, we're not insured for it!"
"Because you wouldn't buy us what we need to DO OUR JOB!"
It was not some utopia. At times it was amazing, but a large percentage of the time was absolute hell on earth thanks to utterly appalling management.
