===Introduction===
Boo Tracker BooTracker is a simple, yet powerful music tracking program. Written by [[Simon Forrester]] (aka Boo The Ghost), it appeared on Amstrad Action covertape No.26.
The software enables you to track your own music, using either ready-made instruments, or you could make your own in the instrument editor. You have 3 channels to work with. The finished arrangements can be saved as a .mus file, which will play back using an interrupt, so you can incorporate them in your own programs.
BooTracker used firmware sound routines, rather than directly addressing the [[PSG]], so was unsuitable for demo or more advanced game use. Nonetheless, it was capable of very good results, not least because of the firmware's 100Hz sound-generating frequency. Perhaps the most impressive product of BooTracker was the 'Jean-Michel Jarre Demo Disque' by [{SWiB]] of [[The Underground]].
