First, let me say that this app it super great overall, and it allows for some really cool videos. However, there's a few areas where certain things didn't line up completely correctly.
I released this video yesterday, and I noticed that there were a few glitches and jolts with the Saber.
The other thing is that I can only control the color of one MIDI channel when changing it.
Other than that, I found the app extremely nice and useful!
