Hi everybody.

I'm new to these forums, so I greet you all !
I'm writing you because I'm not able to connect Logic Audio Platinum to my brand new TR-Rack using Logic's built-in midi driver. I've managed to do it with OMS (the expander responds right), but I don't like it because it seems very buggy to me.
How can I connect it using built-in midi driver, which they told me is far more reliable ? My hardware is :

- Yamaha W7 as a master controller
- TR Rack
- Midiman 1x1 USB midi interface

Thank you for every answer.
