Sysex editor

I use the roland expenders to make a song but it’s impossible to dump the sysex file with Renoise. Do you have a solution or when do you do add a sysex editor?

Thank a lot

P.S. Renoise 3.1 with redux is a very good stuff, great

Can’t the Guru tool accept sysex? You’d have to make a profile for your particular gear but it might do the trick…
