Hi Scott
You are correct as far as it goes.I use MidiNotate Composer to play midifiles as moving scores.I also have leadsheets scanned and organized for numbers using nothing but the keyboard.My problem arised when I have a full page score.I have to reach up and push pg dn.I can zoom out,but the print becomes too small to read.

The Musicpad Pro does not play sequences etc,etc. It is very good,however at organizing,editing,and displaying scores.

Scott Yee can tell you much more,but from what I have seen.it does a great job for what it is intended to do.It is larger than the average laptop screen,hence you can display it better.
