Esh, here is a response from EastWest concerning program changes with Colossus:
'The Receptor/Colossus bundle was going to be Colossus Live, we just haven't formally named it as such - but it's the same package (and the deal ends November 15).
No, you can't do real-time program changes as the samples are big and need to be loaded - they load pretty quick though.
I hope that helps.
