Thank you to the pair of you for looking in here.
I've made a little progress but not out of the woods yet.
It appears I never carried out the first step properly in the adding 'Control Surfaces' dialogue by choosing 'Frontier Tranzport' as the 'Controller Surface'. Mine was left as an ACT Controller with me only adding the Tranzport to the 'Input Port' and 'Output Port'. Therefore, my steps outlined in first post are amended to read as an instruction:
8. In Sonar, go to Options>>>Control Surfaces and click the little yellow + button/icon to add a surface and select 'Frontier Tranzport' as the 'Controller Surface' and then select 'Tranzport' for 'In Port' and 'Out Port'. Ensure this is confirmed in the 'Connected Controller/Surfaces' list before clicking 'Close'. With the above change in setup, I am now able to move through the tracks of my project and mute/arm/solo/play/record/stop/rewind/forward and use the wheel to move through the timeline.
My only issue now is that the Tranzport's screen is blank and remains so.
I've no idea what's going on. At least I'm now able to do what I primarily require the unit for - this being Remote interaction with Sonar. It sure would be nice to see something on the unit's display though.
Funnily enough, the top row of characters look like greyed out blocks. However, earlier today I had the first character blinking darker than the rest - kinda like a type cursor would flash.
Any ideas? Dud unit? I hope not as I bought it a month ago and never had time to test it at the time. I've squat chance of a refund.
