I've had fairly good luck with both the TR909 and 505 via midi sync.  If the
tempo is stable, they borth fairly solid up to the 300 BPM I've ever tried
(mainly just the see how fast it would go).

But I could confuse things a couple of ways.  If I wanted to make a
stuttering phrase by pressing stop, then continue again and again on the
909, it starts sending erroneous extra clocks, and things begin to drift by
1/96th note at a time when that happens.

Also, if I very quickly ran the tempo knob up and down again and again,
things would lose sync...but gentle transitions are usually rock solid.  I
have a feeling that you have to be running things quite a bit faster then
300 BPM to make it so that the clock response handler is cut off my the next
clock.
