24io and Audio MIDI Setup
The issue: Audio MIDI Setup sees the PCI-424, but it only shows 8 ins and 8 outs. I have a mac pro 8 core with latest OS; Sierra. I can record and playback through the first 8 channels, but the other two thirds don't appear. Am I missing something here? Does anyone have a similar setup that works correctly?
Music is not a job for me, It's a passion.

Re: 24io and Audio MIDI Setup
You should have a MOTU app called PCI Audio Setup on your Mac. Run that and see if all the inputs and outputs are enabled.swampfox wrote:The issue: Audio MIDI Setup sees the PCI-424, but it only shows 8 ins and 8 outs.

Re: 24io and Audio MIDI Setup
Thanks, James. The app that you mentioned was the problem. I had to download an updated version of MOTU Audio after which all the inputs and outputs showed up.
