Keyboard slow respond time when using instruments

My Nektar Impact LX88+ appears to respond poorly when I load a virtual instrument. When I create a new "Software instrument" track, it appears that all midi signal goes in and is registered without delay, but when I load something (like piano, strings etc.) it takes 1-5 seconds before anything responds from my keyboard. This goes for faders, keys, knobs and so on.

I've tried a different keyboard and it works fine with no delay combined with virtual instruments. I already know this isn't a recording latency related subject.

Is there a reason why my one keyboard won't respond well when an instrument is loaded.

iMac 27" 5K, macOS 10.15

Edit: After trying several methods I found the solution:

(From Nektartech's support)

Close any applications you have open.

Open a Finder window.

Open the ‘Go’ menu at the top of the screen.

Select ‘Go to folder…’

Type ‘~/Library/Preferences‘

Click ‘Go’.

Find com.apple.logic.pro.cs and move it to the trash (Important!)

Empty the Trash.

In the Finder go to //Applications/Nektar/LX49 or //Applications/Nektar/Apple.

Run the uninstaller located in that directory.

Restart your computer.

Start Logic and create an empty project (this is just so Logic creates a new cs file).

Quit Logic.

Run the latest installer (the latest installers can always be found on your Account page).

Start Logic again.
