I am looking for a keyboard with decent piano like action that I can record several tracks of 3-5 minutes long, then play it back so I can play along on my grand piano. I have only had basic keyboards in the past with good acoustic, electric sounds. Would the Roland FA-08 enable me to do this? Would any keyboard with a usb port allow me to do this? I don't want to have to hook the keyboard up to any external software, computer, etc. Please forgive my ignorance in this area. Thanks!
