I'm happy you could make use of the editor. I currently have no timeline for changes or a real todo list on what I want to do with the editor.
Due to the ever evolving security restrictions, which are being introduced to the different browsers I will most probably try out a java version for the editor.
The real round trip back from the VZ to an editor or wherever must be initiated by the synth itself. My workaround currently is to dump my VZ via MidiOx and to then re-load it to the editor.
Also, I did not put too much further effort in the editor, because there was no feedback, whether someone finds it useful or not.
Kind regards,
Pete
