Once you get the system to sync you'll be very happy...Try this. set your sequencer to External sync. In Protools setup the session w/ bars and beats and enter the same bpm as the sequence. In "session setup" you should be able to tell Protools to send midi time code out to your k2500. press play on Protools.. the sequence should start.

If you find yourself going bonkers w/ the Midi thing... here's a solution that will take advantage of Protools strongest suit.

Create a bar of click at the beginning of your sequence.
Play your sequence 2 tracks at a time into Protools...( make sure to record the bar of click w/ each pair)
When you're done, simply sync up the tracks "by hand" using the click reference.

Good luck
