there are many links here to downloadable patches, and many of those pages have tutorials and instructions on exactly HOW to do it too.

Basically you need some type of patch librarian software (also available at the link above) to store the patches in (there are many more available than you have room for in your user bank.)

I'm not familiar with your exact model so I don't know how many user spots you have, but however many you do have is the limit of how many you can have INSIDE your module at any time -- the others will need to be stored in your PC in the librarian software and loaded as you wish to use them.

You then transfer the new patches by one of several methods (.svd format, .syx format or midi file format). Again detailed instructions are on many of the linked sites from the link above.

hope that helps,
