i tried the ez 2 upgrade from 1 but had big problem with launching extra ez tracks it seems everything has to be done in ez 2 on 1 track .in ez 1 you can launch multiple tracks and it works a treat if you do it in ez 2 you get a you are running a 32 bit prog with a blinking screen . i liked the articulation feature in ez 2 re but the rest was quite frankly shite
