hello everybody, i'm coming with the same problem some other logic exp new users had already have it, and i just ask for any help to be detailed if possible. the main problems i have with this funny logiciel : first is to jump to another track while i did record the first chosen one; once i open a new track with a new sound, it seemes like all the tracks played in the Midi are the same, the new recorded one get muted...i cannot understand what i can do with it. furthermore, the sound come out from my keys( korg i3) not from the speakers linked to my monitors... i do use only midi; no audio at all.
