My spyware program recommended that I delete a certain file in the trial Pianissimo program, and now it won't start. It was probably a false alarm.
I didn't think the piano sound was that much better than the PSR-S900's Live!WarmGrand Piano, especially in the mix, and I did notice latency even with the ASIO drivers on my Saffire LE.
I'm not going to go crazy on this. It looks like to get a really great piano sound, I would need a more powerful, or better yet, second computer or a great piano sample loaded on a separate hard drive. I'm not going to do that right now.
It's a big hassle to deal with midi with Yamaha, since I cannot choose a USER voice within an SMF.
I'll just live with the stock piano sounds - for now, until I can afford a Giga quality piano and the computer equipment to handle it.
