Yep thats how I ran this session - and I agree, its one thing to do a vocal track in a small room with no verb, but then having to do the take with no monitoring of your own sound in the mix in order to keep the click seems just silly. I lowered the buffer to nothing and still had some latency - so we did the takes 'dry' - in low latency , which affected the singers performance - that will have to be re -recorded.
But afterward, too late to benefit this session unfortunately - I made an auxiliary track for the click - sent it to an audio track and recorded the click onto it. I never use click usually so this was a new experience for me. Seemed to work and sync up as well as the original click. Having a recorded click means you can run low latency -
I tried a similar thing bussing reverb to the master fader from an auxiliary track with one track recording - and it worked in low latency mode -I didnt get the message coming up.
