Ted, When I was using a Laptop for my leadsheets I simply used the standard PDF reader. It worked just fine.
Now I use my Ipad and it is a perfect solution. There are several very good apps available - all for under $3.00.
John, Are you sure you really want to sell the KMA? I just love mine and use it on just about all my gigs now as a stand-a-lone keyboard. You might want to just hang on to it.

Deanne good to hear the KMA is working out for your needs... in case anyone forgot how good it can sound here is a repost of my KMA demos when I had one ..
