It would have been helpful if you'd given some indication as to what did work, and what did not.
I've checked the manual on-line for the YTP, and I note that the midi implementation is slightly limited, so some things that do not work might be due to that. The controller might support more commands, for example.
If something does not work, check the two implementation charts.
One thing, I see that the YPT does NOT support midi note OFF. This could cause problems if your controller sends such info, as it will be disregarded, causing hanging notes. The YPT will need to use note ON but with zero velocity. Maybe something can be set on the controller to effect this?
