Doing the standard data cut mod with a patchbay was far FAR more involved than I anticipated but it is done! Yay! :D Definitely will have to do some labeling on this one eventually.
Nice work. Care to upload some sounds?
I'll post a link tomorrow or the next day. I'm trying to be methodical and work my way through at least a good deal of the combinations. Using the manual that somebody posted a link to on here for the YM2413 I've been able to purposefully set a few parameters. Overall, not as "fun right out of the box" as the pots I put on my last project.
