Thanks guys. I've started checking out for solutions on my side. One of the things which makes it harder to handle is that I don't have access to the individual presets, only banks of them.
So I can call up a global preset bank from my host browser, but all the navigating from one patch to another happens via the synth's GUI.
Obviously, I could just skip problematic patches and not save them as presets, but, if there's any (relatively simple) way I can fix something instead of avoiding it, that would be my first option.
Did I mention I hate it when synth manufacturers and preset makers ignore all conventions and try to be original instead of just using simple/descriptive names?
Sayeth the guy who's had a lot of fun re-saving the Zeta factory patches (or is it Z3t4 + ?)
