Hi Lucas, I'm happy my suggestions lead to you actually having fun with testing. Testing can be boring sometimes, but it seems you had the time of your life :-) As always I commend you for your effort in detailing your tests. That's definitely important. I hope you, Mike Oliphant and Takashi Iwai manage to write the best possible patch. Of course there will be room for improvement as more people test their Roland gear on Linux thanks to the three of you, but such is the way.
