For some of our songs we play along with pre-recorded parts/cues. I have been using an old VS1824 but we have a gig abroad which means flying there, so I would like to use a laptop instead. I have a decent stereo interface that's more than good enough for the FoH: I wondered if I could configure an aggregate device so I can use the headphone output to provide a click+mix for the drummer? He would plug this into his in-ear monitor mixer so levels wouldn't be an issue. The audio host would be Logic Mainstage.
Anyone use this setup and have any experience? Glitching? Time shifts?
