Reason will work with Logic in Rewire mode.
If you boot Logic first, then boot Reason, youll be able to make an aux channel that receives Reason's audio. Playback and other transport control will be seen by both so if you need to work inside of Reason, Logic will chase, and viceversa.
When you are done, quit Reason first, then Logic.
Thanks Gio.. Have another question..Are the loops in logic,especially the drum loops, bad to use for songwriting? I mean would they be hard to E.Q. because the parts cant be seperated? Or would it be ok to put a general E.Q. on the whole loop, and then use it on one single track?
