Hi boreg.
There is a bug there, I'll fix it. And I think I will relocate the sync banks button as it's a bit confusing.
You don't have to click this button when you select a bank (this is explained in the download link I posted a few posts above). When you select a bank, the panel will request the whole bank. As this is very slow, the panel create a file with the patch's name for each bank, so the next time you select the same banks it will get the patch list from this files, avoiding the dump.
If later there are changes in some bank you have to update the patch list files, and this is when you have to click on "Sync Banks". With this button clicked, when you select a bank it will request a bank dump and will update this bank's file.
ZitatAlso, the editing seems uni-directional - changes made on the Virus are not reflected in the panel. Is this normal?
This is as well explained in the download link. Be sure MIDI Device ID is set to 1. (Config -> MIDI 1/3 -> MIDI Device ID: 1).
I'll add an option to select the Device ID.
