I'm unaware of if this is already being considered, but icJukebox does not work with the current up to date version of Noteblock Studio. You have to use the old Noteblock Studio (which is restrained to only the old instruments, as well as lacking a lot of the other features of the up to date one.) There is an updated version of the plugin that works for the new NBS here. Here is the up to date NBS, and here is the creator of the old one officially endorsing the up to date version of NBS (see the banner at the top.) I'll answer any questions that need to be answered.
