If they’re looking for feedback…I’d love to see it able to detect bar lines. That’s what I do when I use tap tempo–it gives an evenly subdivided count in between–which makes MIDI and whatnot work more evenly, IMO, as opposed to the beat by beat. When you do that, sure the count follows transients of kick/snare/kick/snare, right? But, if you lay a horn part from verse one to verse two, you’re changing the inner measure timing of the part just because the drummer rushed a snare or something.
I suppose you could manually cull out the events of 2,3,4…but, at that point, merge tempo from tapping+warp editing is just as quick. If they would let you define 4/4 and just register every fourth beat…that would be the best of both worlds.
