I'm a Logic 8 user who doesn't own GPO, and has been asked to collaborate with a fellow muso who uses Logic 7 and GPO v3. I didn't know about the arrival of GPO v4 and it's new ARIA engine until today, so was expecting to buy GPO v3 and the two of us would be fully compatible. If I buy GPO v4, which doesn't run on Kontact, can I import my colleague's v3 sessions and be sure that I will be hearing exactly what he did? This is a gig where time is money, so I don't want to find myself with complex tweaking, re-allocating of instruments etc. just to get back to what was originally sent to me.
Thanks in advance,
