I just added the Roland VT-3 to my system.  The driver installed but I can't use it because the driver check box is grayed out, in the preference audio input/output drivers.  The unit is working and I don't intend on using it as an audio interface but would like to record directly to a dedicated track.
Thanks for any help you can give.

If you are in ASIO driver mode only one audio I/O driver may be selected at a time. This limit is set by the ASIO spec. Deselect the current audio input and output settings to make other devices available.

Thank you.
