Syncing Logic & Mt4 With Midi Equipment, i need best possible timing Options

[tacoboy]

I have logic 5.5 and an MT4.

When I record my synth to an audio track in Logic the audio seems comes in a little late. I thought that the MT4 automatically corrects midi delays with Logic and external equipment. Im aware of the "delay to midi devices" feature within Logic but what is the best setting for this?

Are there any other things that should be done to make the timing perfect when recording audio into the computer with midi?
