Solved a gotcha!
I’ve been having issues with Kontakt not always receiving the notes I was playing on the keyboard. They show up in the MIDI monitor but just don’t make it to the Layer.
On investigation it turned out the Layer wasn’t passing through notes with velocities greater than 110 even though the settings were 100% sensitivity, min at 0, and max at 127 which one would think is ok.
Recreated the Layer with the same settings and it now works as expected. Must have been a corruption in saving the original layer though I couldn’t tell you which release caused it to happen.
