like tempo changes without recalculating all later event
times -- this also allows prequeuing without emptying and
reloading the queues on tempo change. in general, it makes 
all timing calculations (quantization, arpeggiators etc) 
one level easier, and they do tend to get hairy quickly
enough.

but you'll probably end up wanting to use a sequencer to 
store and/or (re)generate them, based on musical time.
