Logic Pro, h8000fw and MOTU 828 Mk3

[urowho]

OK, I'm beaten. I'm running an 8 core macpro with a MOTU 828 mk3 and the H8000fw both on FW.

I went to audio set up and have tried a selection of drivers to build as an aggregate. At the moment the 8000, MOTU and all of the native drivers (just in case). I then have chosen the aggregate device in logic. This gives me 34 channels or so in an out (although there should be 40 if they are all added up). I cannot get any sound in or out of either device, I cannot send a loop to either device, no matter which output I choose nothing seems to be going out.

If I choose the MOTU or 8000 as the audio device then audio again appears.

Any chance of some friendly advice 😉

Sorry – this is beyond the capabilities of this forum – given the number of different products involved, it's difficult for us to know what is wrong.

BUT – have you tried the Aggregate Device tutorial in the User Manual ? If not, please do. If you have, did it work ?

If it did work, try the same thing but using the MOTU in place of the H8000.

Note that the recently announced 5.5Beta has new drivers that may (or may not) help.

I've solved it.

Second FIrewire card. Aggregate driver, MOTU 1st then h8000. Final thing to check was that logic for some reason had moved the output to channel 15-16. Hence the main out was quiet and everything was going to the h8000. Once I reset it to channel 1/2 it was perfect. Very nice sounds ++++
