LG VX-6100

I was told by a Verizon store person that you can use a tool such as Goldwave to convert an MP3 file into a MIDI format that you can then upload to the vzwpix.com website and then download to your VX6100 and use as a ringtone. Has anyone been able to do this? From what I can tell it is pretty impossible to convert an MP3 file into a MIDI file without it sounding horrible. Also Goldwave does not let you save anything as a MIDI file only as a MIDI instrument sample (.sds) format. Is there an easy way to convert and use an MP3 as a ringtone in this phone?
