The TranzPort driver Control Surface Plug-in for Digital Performer® are no longer being maintained.

The drivers do not work in later Mac OS versions. There is no solution available to connect TranzPort to a new Mac.

If you have questions your best source of information would be the user community for the DAW software you are using.

Archival copies of the older driver and plugin can be found at these links:
