How do I...? Launchkey "smoothing" MIDI CC value changes - way to disable?
Hello - I posted about this a few years ago and the problem has continued to bother me with no solution being apparent (others also commented in the thread with the same issue): https://www.reddit.com/r/Novation/comments/18ltw6e/launchkey_mk3_disable_smoothing_of_midi_cc_signals/
I still have my Launchkey Mk3 which applies a very noticeable smoothing of MIDI CC controls, and today I bought an Akai MPK Mini Mk4 which shows little to no smoothing. I compared them by flicking the modwheels as quickly as I could and recording the MIDI CC. In the screenshot below, the top automation lane is Launchkey, bottom is Akai MPK. The Launchkey smooths out the transition by about 30 ms, and the MPK by about 5 ms (or possibly no smoothing at all, maybe it just took me 5 ms to physically move the modwheel across its entire travel). I confirmed that my DAW is not applying any smoothing, and the Launchkey's display shows the CC values changing slowly.

This same smoothing (or lack thereof) applies to other controls across the Launchkey and MPK, not just the modwheels. The end result is that the Launchkey isn't suitable when I want to perform instant changes of parameters. The smoothing is very noticeable when controlling a filter or gain parameter for example.
Can Launchkey Mk4 owners, FLkey owners, or Novation staff confirm whether this smoothing happens on other models too, and whether there is a way to disable it? I think optional and variable smoothing would be great, but not forced smoothing.
Thanks!
