VERY COOL VIDEO!!!! Scrolling channel feature is F-in AWESOME!!!! Can't WAIT to get to use this!
Here's a thought from a PC Geek. If we're not using the internal PC board, Mackie software, etc. Why not simply replace it completely with a more modern PC motherboard/Chip combo, and MAKE a self contained recording PC/ Control Surface combo? I will open up my CPU and have another look and see if this would be remotely doable. It would be cool to have a small Quad core rig in there with a large single drive and maybe a SSD running Win 7x64, but I need to look again and see how the CPU Power supply integrates with the rest of it, and how difficult it will be to swap in a much stronger PSU.
I think it could be done though...
My reasons for trying are simple, much less weight in my SKB Rack Case if I dont need to have 2 CPU chassis in it. Everything could be contained in the Mackie's original case, with a few rack pre's and good to go with less to lug around for a mobile recording setup.
