Novation Controller on different VSTi

I have Novation Launchkey 49 MkIII.
Using Spectrasonics instruments.
When I go from one instrument to another, it seems if I assigned a fader or knob to one instrument, then it is not available to another one. Is this expected behaviour?

Hi and welcome to the forum,

How did you assign the fader or the knob, please?

Right click on the fader or knob and assign.
This is within the Spectrasonics app.

bump!

Hi,

Sorry, I don’t own Spectrasonic, I don’t know, how do they handle the MIDI assignment.
