It is my understanding that Rewire is an integration feature for merging MM with other parograms from other vendors....I found that in the Help Menu/files that are included with MM praograms.  I suggest you open them and start reading them as athe potential for lots of potential problems certainly exists, especially trying to merge music programs....can't say it can't be done, if Maagix offers up such a program, but I see shooting yourself in the foot is extremely likely.....I suggest you procede with caution.....and make notaes as you go along
