Any software for SP808EX?

Hi, I just downloaded the Wav converter from Roland but its features suck. Has anyone come across any other (3rd party?) software that will allow you to do things like save entire songs or rearrange tracks on the PC?

I mean if the Zip disk stores an entire configuration there must surely be a way for sw to mess about with a song and write all this back to the disk.

thanks... I'm using mine in an electro band and it's a great tool for live gigging.
