I have the good fortune to have an IOS, IOX, DLS and DLI in my studio (I am a beta tester for this product line). I have been using the DigiGrid system since December 2014 and have posted reviews for the DLS, IOS and IOX on GS. Just letting everyone know these are out there. I have used the system just a little with Logic ProX (I know PT much better but am improving slowly on Logic). Regardless I would be happy to help with any questions if i can.
