Hi

I may have given you a duff steer there.
The only control you have in BIAB is in the midi latency setting but that is more of a visual thing to keep the screen display in sync with the midi notes you hear.
But it does seem that you are sending more midi data than it can cope with and the problem seems to get worse the more you send .
I will do some test using my Yamaha Clavinova later and se what I can clean from that.
In the mean time you might like to visit my web site technical articles section where you will find many articles on midi and Yamaha keyboards .
Some thin there may be useful to you at some time link in my signature at bottom of post
Have fun
Mike
