i guess i like documenting things don't pay attention if it doesn't interest you! (not really expecting to get any replies)
anyway i wrote a more complete manual for digistudio, in html format. digistudio is a 4-channel mod-tracker for MS DOS if you don't know already.
you can peek at the manual here http://aanaaanaaanaaana.net/stuff/dsmanual.htm
or download digistudio itself (and also the manual is included in the zip) here: http://aanaaanaaanaaana.net/tools-archi studio.zip
have fun
