AHA - you have the dreaded "can't wait" syndrome, just like the rest of us :)
You DEFINITELY have some setup work to do, despite your resounding success at playing an MP3 file.
I believe we need to revisit your interface driver installation vanishing act in the middle.
I would suggest:
1. Take a moment - order some pizza, get a hug
2. Download the drivers again from Roland. Maybe something there did not download cleanly
3. Give me a hint as to what you mean when you say that your system is 'not completely finished yet'.
4. I have a hunch that when you switched to ASIO, that the reason it didn't show anything was that your ASIO drivers are not actually installed as of yet.
5. Go get another hug OR a slice of pizza
6. Let me know when you have the drivers downloaded again, and I will be on hand when you are ready to do their installation. If you want, I will send you a private message with my cell, if you are in the states, and you can call me when you are ready to install your drivers. Just say something in your post reply.
Folks in the forum help each other out with drivers and setup LOTS of times, and I am confident we can help you too.
So, I will look for a t least one post from you, that will hopefully contain some idea of what your system specs are, also telling me you have downloaded the interface drivers again from Roland, AND whether or not you want me to send you my cell, so that I can walk you through at least part of this over the phone.
Welcome to our happy little family, by the way,
