Default Re: Help configure PT with two Apogee Symphony I/O via ThunderBridge

Thank you very much for your input, and the PT 32 I/O limit reminder.

I have a chassis with 2 8x8 cards and a second chassis with a 2x6 (that's why I had to use 2).

I think you nailed the problem on first suspicion. I first tried to clear all ADAT and AES digital IO from the IO matrix on Pro Tools with no luck (second Symphony still out of 32 range, no matter what I discard.

Then, on Maestro I tried to remap all the Analog IO to the first 32 "slots", but it seems I'm stuck with a rigid matrix I cannot modify at will. The main problem seems to be that the Symphony 64 ThunderBridge forces the second unit to the 33-64 range, on a separate stream, and I have found no way to change that.

I'll try to get away like this, take a look at screenshots please:

What exact modules do you have in each chassis? Your signature is a bit confusing. If you just one 16x16 module in one chassis why not add the 2x6 module to the same chassis? Why does it need to be in a separate chassis?

Only Pro Tools HD/Ultimate using a DigiLink interface can access more than 32 inputs and outputs. For any other systems Pro Tools only works with the first 32 IO. I suspect the issue here is what does ProTools thinks the first 32 inputs and outputs actually are. If you can you need to map all the IO in Mastero to be below the 32 IO limit. I'd just contact Apogee support of your questions are any deeper.
