YO Juan Jose,
Congrats on your new Tyros 2. I also bought mine from Dan O and was pleased with the purchase from his store.
I also live in CALIF where you live. Maybe we are neighbors.
We have a forum going for Tyros 2 here in the Synthzone now. click on: http://www.synthzone.com/cgi-bin/forumdisplay.cgi?action=topics&number=39&SUBMIT=Go
I have also started an email list for Tyros 2 owners for info, music, etc. if you want to be on it click on the mail icon above and email me.
Best to you and your new Tyros 2.
Bebop
