Sorry for the oversight,Robert. I forgot you had an Axiom.
You might want to take a look at this link to the KVR forum. Dasher the Soundsmith is a gigging musician, and has developed an amazing rig from the Axiom. We have receptors, but it is nothing but a dedicated rack computer. The scenario still applies. He has it souped up to do a dozen things at a moments notice. http://www.kvraudio.com/forum/viewtopic.php?t=146476&sid=1f95ab685f38d901b6e594364fcdf37b
To me, it would come down to whether you plan to use two controllers. I have the Kn7000 on the bottom, and Axiom on top. It works well for me, but I don't know your intended setup. I need more than 49 keys. What is your other board ?
