OPEN UP NEW TABS AND THE MUSIC WILL WRITE ITSELF!!!
All Credit goes 100% to SongeLeReveur for this brilliant idea. "The point, here, is to have several of these videos running at the same time. You can open in new tabs as many of these track as you want , at anytime. You don't have to worry about them being unsynchronized. Here's the Bongo Part to Operation Space Station. Open some more tabs and instruments! Change the volume levels, play around with the start times... You're the mix engineer for Operation: Space Station!
