Rewiring Reason into Logic is fun!
I've been using Reason since v1, stopped upgrading at version 6.5
Bought a new MBP and Logic this year.
I haven't installed Reason on the MBP because I'd have to have a USB hub. 2 USB ports on the MBP, 1 for USB3 memory stick, other for audio interface, would need a third for the Propellerhead's dongle.
But I have Reason and Logic on the iMac, when I remember I can do it I have endless fun.
