you do not need to post an mp3 demo of your sound to upload a patch.
guess you would need a printer (printing the patch sheet)and scanner
(filling in the patch sheet and scanning it back into your computer).
unless you can do it all in a photo editing program. no patch to
small. but we would like to get some good ones in there. : ) . if you
decide to upload an mp3 sample of your patch dont make it to big.
yahoo does put a limit on space. look forward to dailing in your
patches. happy tweaking!
