Hi All, I've got a question regarding latency in monitoring while tracking. I am using a Mackie Onyx 1640 with firewire going into a PC running ableton. When tracking I have several different options of signal to send to the musicians headphones during tracking. First option would be to simply send the analog signal straight from the mackie into the headphone amp. This option seems fine until you want to record to a click, do over dubs, or track using effects through the DAW. Ok, so the Mackie in that case has an option to send the firewire signal returning from the computer to the main mix which I can then send to the head phone amps. This signal would obvisouly have latency accrued while being processed in the cpu. The project at hand is to record a 4 piece band performing together to a click track and then do overdubs later. I obviously need to use the firewire signal to get the click but should I use it also for monitoring the instuments or should I mute those in Ableton and use the analog signal direct from the board? I imagine that this is maybe not acceptable as the click would be later than the click by the latency of the cpuc, 5ms-10ms or so? I have the ability to run each musician their own mix from the aux bus on the mackie using the analog signal but can then route the firwire signal from the main mix and send it to the auxes as well - perhaps have a blend of both. I'm guessing this should not be done due to latency and phasing issues? Should I just have all the muscians listen to the fire wire mix while tracking? In terms of latency it seems as though my machine runs pretty well with ableton set to 64 samples which I think is about 5 ms delay, would this acceptable for tracking, or can it be higher? I also noticeed that ableton has a latency setting for plug-in buffer, should that be set to the same delay as the hardware? Thank you!
