Exporting Jamcorder files as audio files

Hi, all.

Am considering purchasing a Jamcorder, but would like to know about how it exports files.

I can send Jamcorder files as audio file attachments to iphone messages and the recipient doesn't need any special app to listen to them? The audio file will sound like what I'm recording from my digital piano?

Do I first need to convert the midi file to an audio file and then send as attachments?
