Funnily enough I just had a similar thing with a 16n Faderbank I just acquired and the best solution I found was to map the CCs via Stoermelder’s uMap as that seems to force refreshes of everything mapped to pick up their current positions.
The Stoermelder modules need to be manually downloaded and installed as they aren’t in the v2 VCV library, but it’s a reasonably painless process.
