windowing is about keeping the loop length and moving the start point.
long press of undo moves the start/end points in loop-sized increments, 
short press allows moving it to the middle of a loop, but the size stays 
the same in both cases.

it's lots of fun.

there is a parameter called 8ths per cycle.  once a loop is created, bpm
is calculated using loop length and the 8ths per cycle setting.  
i'm assuming it uses the formula: 
8ths_per_cycle/2/((sample_count/sample_rate)/60)
i'm sure it would be optimized to avoid all the divides, though. 
as i recall it, there was no fpu on the 68000...
