I was having the same error when exporting presets from my Space to the H9 Control. It happened with a presets that had an asterisk (*) character.

If that helps to you.

Thanks very much for your reply.  I don’t think that’s it, though.  I don’t really have any special characters in my preset names.  I do have some + and – signs in the names to designate in the name if I’m shifting up, or down a third for my Pitchfactor.

It’s weird: same problem on 2 different computers…
