Many people are complaining about something they think is an error, so I'm just going to clear up this...

When you choose a song, it will always give that error, "server error finding note tracks". We will fix that thing later. So what you have to do, is simple. Can you see that button at right below, where it says "Use your own track"? Click on browse, select the midi file and it's done, have fun :P There's nothing stopping you from playing on it!
Hope this helped those who were having trouble with that.
By the way, we will try to figure out a way to use the option to Record Tracks, it may be already possible to use on the next edition of jamproject =)
