By popular demand, you can add your own patches, wav samples, and performances here. Just give it a nice name (with your name in it for due credits), or mention your name in the message field. Patches and performances should be zipped. Once you’ve done your upload, we’ll check it and put a download link on this page. Thanks! 🙂
