Recording Main Mix from SD playback

Dear A&H-community,

I recorded a concert multitrack to the SD card. Then I adjusted some settings on the CQ to improve the mix of the playback. Now I want to get the new stereo mix out of the CQ.

I tried to record MainLR to USB while playback from the SD card, but that doesn’t work.

Any ideas? Thanks for your help!

I don’t want to copy the files to Logic and redo the improvements I made on the CQ. And I don’t want to use another recorder to record the MainLR of the CQ.

Best,
Raymond

Proposition for feature request: Having the headphone outputs as inputs available via USB cable might be an option.
