As I stated, I'm certainly not an accomplished performer. I do play guitar and I am learning piano and fiddle. I'm certainly not a proficient keyboard player. What I am looking for is something that will allow me to arrange some casual performances with the grands. I have read a lot about the PSR 900 and the Music Finder + was especially interesting since the feature would allow me to download arrangements of songs that would be ready to perform. I do have a good knowledge of computers but not much regarding MIDI and arranging. Of course, these arrangers are expensive so I want to know that what I'm getting will be helpful. Thanks for the help.
