I would recommend that anyone interested in learning to use a tracker program like chibitracker print out the beginners section of the Trackers Handbookhttp://www.modplug.com/mods/handbook/handbook.htm
After going through that then you can get by just using chibitrackers online help which tells you all the commands and keyboard shortcuts from within the program.
One of my favourite tracker musicians at the moment is a guy called Heatbeat who, although it wasn't the greatest example of his music, did the music for the most graphically impressive game to ever appear on the OCS Amiga- Elfmania. I've zipped up a number of his songs and attached them to this. If you like old rave music (Prodigy / Streets of Rage style) then you MUST check out his Sainahi Circles, which I've included. What impresses me even more is how good he gets acoustic instruments to sound- he pulls off some pretty jazzy stuff with 8-bit samples and manages to make it sound natural. Of course you can also play these files under xmms, Amarok or any other music app that has MOD playback capability.
Have you tried chibitracker yet Mickey? What do you think? I've had a couple of mods that wouldn't get any further than the 5th pattern before looping- I've sent the mods in question to the author.
Turns out that looping 'bug' is actually a feature of the Bxx command, often used in game music
