Yes, you've got the gist of what I'm doing, Wynnd. And you predicted the problems I had with monitoring feedback, too.
For band rehearsals or gigs, nothing is easier than recording with an external hard drive on the DL and then dumping the tracks into ProTools for mixing and editing. I love it.
Now we want to start tracking, overdubbing, punching in, etc. 32 input channels is overkill for me, but my other interface has only two mic pre's. This will be great for tracking the drum kit.
I bought the DL32R a few months ago but it was only yesterday that I got it to work with my Mac laptop. I could not find any information on the web about how to do this. The reason is probably because the answers are so obvious to people who often set up various interfaces with ProTools. (I'm a dialogue editor by day, so I don't even need an audio interface; just a headphone output and/or speakers.)
As I said, I got it working and I am amazed. I don't know how it manages to record 32 tracks of 48kHz/24bit audio simultaneously through a USB2 printer cable without a glitch - but it does.
So for those like me, here is a checklist to get your DL32R to communicate with ProTools 11 (and probably other versions, too.)
FOR PROTOOLS:
1. Select DL32R in the Hardware Setup
2. Select DL32R in the Playback Engine
3. Select DL32R in the I/O Setup, click "Default" for a quick set up.
4. Latency Monitoring Mode will mute the audio in some systems. If you have this problem, switch off Low Latency Monitoring and choose a low buffer setting in the Playback Engine to minimize delay.
5. Use output 1-2 (This might have been a note to myself, only – it might not apply to you.)
FOR THE DL32R/MASTER FADER APP:
1. The monitor source from ProTools is "USB 1 & 2." Patch "USB 1 & 2" to "MONTOR L & R" for headphones and to "XLR 13 & 14" for speakers. (This is the default setting for listening to the DL's main mix. You might have set yours up differently.)
2. Leave all channel inputs on "Input A." You might get unexpected audio leaking in through the "B Inputs."
3. If you have a channel or channels set up for hard drive playback, mute them. They will send audio back to the mix that you don't want.
I eventually figured this out on my own but I appreciate your help Wynnd. I hope this helps others, too.
