Think I'm with Bapu on this - I've got the original Tracks deluxe but I din't upgrade to v3 - now it looks I have no upgrade path at all, so shall forget this.
I'm still on Amplitube 2 which works for me so shall stay with that as well!!
I do think IK have lost the plot a little - what I shall do with my Sampletank etc is whilst it still works I shall just stay with it - I don't think I will be spending lots of money on this just to get 64 bit operation, when at the moment they still work as they are!
