Thanks Jeffro, I can now hear the drum track and have input in via the Behringer. Seems the last issue is the input sound (keyboard in via instrument) sounds clear but the output is distorted and cuts in and out. The drum track also does this. Wonder could the Behringer be defective?

I'll try tomorrow to change the I/O to the PT Aggregate I/O through speakers and see if I get the same issue.

Maybe we're getting close.

Thanks for all of your help so far on this, much appreciated.
