Topic: Only a few channels will arm on the DAW.
I can set up with about 8 channels that all work perfectly in Totalmix but in the DAW it will only arm 3 or 4 then just refuses. The 3 or 4 work OK. I'm currently using Reaper but the same thing happened with Garage Band.
I'm using an early 2011 Mac book Pro with SSD and lots of RAM.
