There's the MIDI export video above. I expect there are a few more coming.OK.......but where is the........walkthrough ?????????
But in truth, aside from the MIDI export, I don't think there's much about The Orchestra Complete that isn't pretty intuitive to use if you have The Orchestra. Same thing, just more instruments, presets, and stuff available to use in the engine. But they did say there are changes to the interface so we will learn about that. I'm going to get it within the next few days, so I'll post about it if nobody else does.
