Yikes - 16 years and this still isn't figured out? I'm dealing with a similar situation, with an HR-16 drum machine (translating/converting old sysex dumps to something useable in a DAW). The post from 16 years ago pushed me in a right-er direction, but now that I'm seeing this one, I think I'm giving up - because I barely know anything about this kind of thing. If people who do know about this stuff haven't gotten it to work, what hope do I have... At minimum I'm simply trying to figure out version number of software on HR16 from which my sysex data were dumped (that's supposed to be in the sysex data)...
