I got this keyboard when I was in a church praise band. No digital keyboard will ever be as good as a real piano, but this one sounds pretty good in a band.
The speakers aren't that great, but you can hook it up to an amp or a sound board using the 1/4" audio out.
It's capable of saving what you play in MIDI format to a SmartMedia card. This is great because I play by ear, but a guy in the band needed the sheet music, so I just used a program I had on my computer to generate the sheet music from what I had played.
There's lots of different sound effects, so it's fun to play on too.
I bought this keyboard when I was in a little praise band in my church. A professional musician will probably want something a bit nicer, but for small gigs this keyboard is great. A very fun instrument!
