I'm using protools 6.7 and running through some routing configurations with my Mackie 1640 and for the life of me......my 002R does not recognize inputs as Analog 5 and Anlog 6 as MONO inputs...only Stereo. I'm setting up a MIDI track with a MONO AUX= I already double verifeid and re-created my I/O Options: Set Analog 5 and 6 to stereo and set two sub-paths as Analog 5 (MONO) and Analog 6 (MONO)...done it a million times before...I know how to set up mono and stereo paths. You may need to increase the size of these to read them, but my inputs are set up right, they aren't listed as input options. All my other mono paths are showing as mono...Mic 1, Mic 2....all the way up to ADAT 1-8, but still no 5 and 6. I've been having power harness problems, but this doesn't seem related. I'd love for someone to re-create this so I can rule out a problem with ProTools 6.7. Again....set up a mono input on 5 and 6. Oh yea...I'm running a 24/48 session at 6+, not 12+ ....clocked to my Digimax LT and I also have the 002R set to +4 on 5-8. DK
