I'm using logic 4.7 and just samples. In arrange, when should i designate a sample to TRACK and when to STEREO TRACK? In the mixer some of the tracks seem to merge into one channel even though they're set to different ones. Somebody please tell me what i'm doing wrong!

In the Arrage window, u have access to the PARAMETER Window ( on the left).
In this Parameters window there is some indications, DEV ( Asio,MacAV etc...) MIDI Channel, and TRACK...while u clik on TRACK ( and leave ur finger on the mouse...) a menu appears, now u can select the Track.
I hope it helps ? ;o)

... depends on the sample format!
Did you get the difference between mono/split stereo/interleaved stereo tracks ?
(check your audio setup/ is universal trackmode enabled ?)
If not: R T F M ('read the fuckin' manual'!) - sorry - You'll have to be a little more specific.

Kind regards
Walter

P.S.: ...sorry - forget about the babies ...
