In my previous post I forgot to mention one other option for wireless
remote control.  It is not so elegant and a little bit fiddley but
it works.

Let your Pocket PC wirelessly control your computer via a free
web-based program such as Logmein.  You can control any MIDI player
(E-roll player, Cakewalk, etc.), although it is probably easier to use
if you simply have all your MIDI files (or shortcuts to them) in one
folder.

With your stylus, just click on the wanted MIDI file and it should
play with your default player.
