Yep.. Master Trax Pro (MIDI only) will work great, as will Encore (Notation with some MIDI support). I've been using Master Trax Pro v 5.2 for a long time, it's amazingly powerful considering when it was written - I still use it on an old LC475 MIDI'ed up to my studio because of its simplicity and features not found elsewhere even today. You will need a MIDI interface - if you don't have an old one, you can buy a relatively new MOTU MIDI Express XT and it will connect to your SE and work just fine, it has the 8 pin serial port you will need (and USB for that matter). There is no support for Audio in either of those applications. No extra drivers are needed, as the applications talk "directly" over the serial port to the MOTU.
