I'm a logic user since version 3.6 but never started to use it for live recording until recently. I read many threads about latency and stuff, but I'm searching still for a solution for recording live with no latency. My setup: MBP 2,8GHz Intel Core 2 Duo, Focusrite Saffire Pro 40 (with Behringer Ultra Gain ADAT Interface). What I want to do: Recording and monitoring up to 16 tracks (1 vocals, 1 acoustic guitar, 1 bass guitar, 2 bass synth, 6 keyboard, 4 percussion mics, 1 Looper with drum tracks) with "no latency" live monitoring for all band members. The place where I play regularly is very small, so the hardware should be as small and effective as possible. At the moment I record with Logic, but don't use it for monitoring, because of latency. All audio runs through the Saffire and sounds ok. The Saffire stereo monitor mix runs into an iAmp 800 and mono into the PA Boxes. No further hardware mixer should be involved. What I miss: I'd like to use some plugins (mainly eq and reverb). Could it be done better with Mainstage instead of Logic??
