Currently there is a known issue with the UACC and UACC KS mapping where all articulations have the same value. This is something our developers will resolve in the next update for CDT but in the meantime there is a fairly simple workaround.
1. Lock the patch to UACC or UACC KS and click on the first articulation:
2. Click the small cog icon in the sidebar on the left and select UACC #1 for the first articulation, then click the second and assign UACC #2, the third to UACC #3 and so on until all articulations are numbered 1-15.
3. Make sure to save your patch so that you will not need to do this again next time the patch is loaded.
