It is only MIDI.

The chances are that you'll be able to find a program somewhere that will allow you to save and/or export tracks as wavs, or you could try and find a MIDI to wav, or to MP3 convertor.

I've never been able to remember whether it's converter with an "er" or with an "or"...my spell checker usually sorts it out.

I wonder if it's possible to create a spell checker for the forums...it'd sure help with all the typos...
