Hi Paul

Thanks for the update.

Would this change (assuming there's enough demand for it) mean that if 
you were working in 8 time, say 15/8 for example, you'd be able to 
choose that quavers were used for the bpm?

To my mind it sounds as though it could be awkward to be working in 15/8 
but the 120 bpm was 120 crotchets a minute -- a beat is a beat -- being 
able to select so that the bpm is the same denominator as your working 
meter sounds like a very sensible idea. I very seldom work in 4 time, so 
if I've understood this correctly please count me as a vote in favour 
(and yes, I'm into prog!)

On a related note, my pieces swap frequently between different time 
signatures, sometimes every bar, so there are lots of markers. In Ardour 
2 I've often encountered problems with the markers randomly flying 
around all over the place when I come to add a new one and having to go 
back to square one with mapping out all the changes: when Ardour 3 lands 
is its handling of meter changes going to be more robust that 2's?

Many thanks
