I was experiencing noise when using modulation with JABB 2 and Kontakt 5 in two separate DAWs so I upgraded to JABB 3 for Aria and the problem is now resolved. The Garritan Concert and Marching Band also has the same issue with Kontakt 5.
Here's a short file of JABB 2 Bb Clainet 1 using Kontakt 5.

Here's the same file of JABB 3 Bb Clarinet 1 using Aria.
