We are all anxiously awaiting a major update to this. I have become very good at adapting some of the rhythmic changes that I need w/in my tunes, but this is very difficult and time consuming as you have to export the midi info into a DAW, perform any manipulation to the midi and then export it back into EZ keys. Sometimes I’ll pull the drums and Bass to get it perfect when it’s very complex.
I love the product over all, but would be over the moon if it had better adaptability. I’m sure all of their sales would sky rocket if they had an upgrade as the demo users would like transition to purchasing and then buy midi. If I was the CEO, this would be my priority action item for my software development staff.
I have a jump blues project that is killer that uses all EZ products with a vocalist and sax player and people lose their minds. I just wish it didn’t take me a whole day to fabricate parts. 
(I could use a Boogie Woogie vol II and then a Reggae volume II if this every gets read by those that matter LOL.)
Thanks for the great products, but we all know you can up the game on EZ Key’s.
