The debut of the S900 went WAY better than I expected, or even hoped for. I still have a lot of minor tweaking to do, but the sound through the Bose was fantastic. Regulars in the audience all commented on how good it sounded, and I didn't tell them I had changed gear. Incidentally there was no evidence of any phase cancellation through the Bose.
I only set up one bank of registrations, so I was working with 8 setups. The rest I just called up a style and played.
I used a couple of midi files just to see they sounded, and they did fine.
It is fairly easy to call up lyrics (test files). They CAN be associated with registrations, but I haven't set any up yet, except to test.
The feature that allows you to record to portable media works great. It even assigns a name to the song, and allows you to immediately audition a new recording and choose to delete or let it stay saved.
Stupid me, I brought home the wrong USB drive, so can listen to all of them until tomorrow.
More later,
