I have recorded a song on the Music Studio iPad app, and am able to export it as a WAVE, MIDI, or .xms. The song plays flawlessly on my iPad, but whenever I export is as a WAVE, it stutters too much to be pleasant to listen to. I could either get a strong MIDI player, or an xms player. I want to have the final product be an MP3. Another option would be recording software that would allow me to hook up my iPad to my PC via headphone and mic port, and I have tried that, but I need high quality stereo recording software for that. So, for my actual question, does anybody know of a good MIDI to mp3, xms player, or high quality line in recording software? (Everything must be free)

Thanks in advance.
