XPMCK

In pmck, A o3 [c>c]2 plays o3c o4c o3c o4c
In xmck, it plays o3c o4c o4c o5c

That shouldn't matter very much, but watch out... more octave bugs (that only occur after a loop that ends in a different octave than it started)!

A o4 d < > d d d ; This example works fine--all four notes are played in the same octave ( the < and > cancel each other out).

(vs.)

A o4 [c > c]2 d < > d d d ; Now the last 3 notes are played in a lower octave!? Uh oh, bug.

(vs.)

A o4 [c > c]2 d < > > d d d ; Now they're all the same octave, but why does it work? Bug.

(vs.)

A o4 [c > c]2 o5 d < > d d d ; This works fine because of the o5. Looks like if you reset the octave after your loop, you don't run into this problem.
