After the latest V 1.6.0 update now using the arrow keys is no longer possible for changing presets when the list of presets is in focus. What happens is after moving some number of presets down the cursor jumps back to the top of the list, holding down the down arrow just loops over the same presets.
This is the only V Collection instrument that I’ve encountered this issue with - MS-20 V, Prophet VS, Analog Lab all work as expected with the arrow keys.
This was tested on macos 13.6.1
