Hi There, I went through the "Logic's Latency Toolbox" tutorial and set up my system for integrating external instruments as directed: External instrument > Input channel strip > bus > audio channel Now when I sent my audio channels to a bus to either add effects or create a sub mix the bus channels are out of sync. Is there a work around for this? I spent a considerable amount of time setting my system up as directed. If I can't use bus channels for sub mixes and effects I will have to go back and redo a ton of work. Thanks!
