Sequencer / Tracker

Hi,

Wondering if anyone was actually doing anything about a sequencery 
trackery thing.

Otherwise (or also), are there any timing routines that anyone has 
implemented, file format (I think a sequencer is fairly useless without 
a format to save it in, don't you?), et cetera, it would be really nice 
to have some pointers or some source code, or preferably both.  I 
noticed what appeared to be a half-hearted attempt at timing routines 
(stating that it needed to be entirely rewritten) in the sources, Which 
is the major reason why I haven't jumped headlong into it...

Regards,

Francis
