Smartphone MIDI player?

[Guest HippyKid]

Does anyone know of a free (or reasonably priced!) MIDI player for Windows Smartphone? I've got an SPV C500, and the only app that seems to play MIDIs is PVPlayer which is less than satisfactory. I'm looking for one that can adjust the playback tempo, and the volume. Alternatively is there a codec for Media Player 10 that I could download? I find it odd that neither Media Player or BetaPlayer support MIDI out of the box...

Any advice much appreciated!

Thanks, Linda
