I was thinking about them playing Losing It. It is clear that Geddy is not playing the keyboard part... he is just holding down a key to play a sequencer...But that sequence wouldn't be in the banks of samplers that they have as part of their gear. If they wanted to pull out Big Money or something tomorrow night, I'm sure those key parts are all stored forevermore on hard drive.
So... would Geddy have re-played the part, finding a similar sound, and made a sequence of it, or would he literally be crawling around in the basement of Anthem or his house to find the master multi tracks of Signals to upload a sample of the keyboard track to a HD? Would they have at some point sampled all the key parts from all the albums just to have them in case?
At first I thought he'd just have his keys tech take care of it, but would his gear tech have access to the original multi tracks of all the Rush albums?
