Hi all,
indeed the embedded components for knobs 1 & 9 are not the same as the other knobs, as you well noticed, since you can also click on these 1 & 9 knobs.
Unfortunately, by design, even if all the knobs have the same acceleration settings, knobs 1&9 will react slower.
One solution would be to implement other acceleration settings (especially when "fast" seems not fast enough for some users)
Anyway these issues will be considered on a future firmware update, but i can't tell when it will be released.
Sorry for not giving more information, but be sure we won't forget it.
best,
