modplug tracker is awesome! But it's a bugger to figure out. You need to read a tutorial.
http://www.roncli.com/modplug/download.asp?FileID=8Download that, it will install 1.6 of mod tracker and it contains a documenet called TUTORIAL.DOC. It helps you create your own song!
The only trick is getting the file gm.dls, which it claims you can get by executing some executable that will download it for you. It doesn't work. I found GM.DLS in the window/system32 directory and just copied it from there to the modplug directory. I made a cool song in under 30 minutes with this tutorial, it was awesome.
I am also still anxiously awaiting Mojo's sound making tutorial.
