I’m not familiar with the jellybean switch, but from what I can tell on Google it connects via an audio jack? So far as I know we only have functionality for USB/Parallel Port buttons, however, if this button is commonly used we could probably add functionality for it. @jon what do you think?
I’m afraid I have no experience with them. @psychisawesome can you confirm that this is normally connected with an audio jack? Have you used it with any other software?
