What is UACC KS and how do I use it?

Last updated:

UACC Key Switch (UACC KS) is a mixture of keyswitching and UACC which provides the advantages of both methods. When UACC KS is activated a single key switch becomes available. Using the UACC spec outlined here the velocity of this key switch is used to switch articulations.

To use UACC KS instead of key switching first you must lock articulations to UACC KS. Using Chamber Strings as an example, first you must open the expert view by clicking the small black spanner icon outlined in red in the image below.

Next you simply click the small padlock (outlined in green) that has now appeared in the sidebar and choose lock to UACC KS from the dropdown menu (outlined in blue), now you will see a single red KS key as shown below:


For example pressing the key switch at a velocity of 70 would switch to the Trill (minor 2nd) articulation while pressing at velocity 56 would switch to Short Pizzicato (again the velocity values are on the specification found here). As with UACC, you can manually input these velocity values but it's easier to use your DAW or tablet app's functionality.

The main advantage of UACC KS over UACC is that you can layer  articulations by overlaying the notes of the key switch on the piano roll. This is why we advise using UACC KS when building articulations sets in Logic.

    Plase help me to use your instrument correctly.

    What is the purpose of using UACC switches (or other) for LegatoPerformance Patch?
    I am trying to use Logic Articulation Sets in Studio Strings but I also know other libraries have this problem.
    Is there ANY purpose to automate it with these switches? It does not work right even with normal keyboard keyswitches. Maybe you should not use the keyswitches at all for this patch? UACC VEL 20, and UACC VEL31, and 32. They do not work well, most of the time if you use any of them then you end up with double articulations on, like fingered and portamento for example, which is not acceptable. In Studio Strings there is a switch to legato and switch to portamento. Is there ANY purpose to assign keyswitches to it?

    Please help me as it drives me crazy making impossible to think of your libraries. I need a full control.
    When you start using the art set control or keswitches the fingered legato usually latches and stays there, making it impossible to use.


    If there is no purpose to use this (because it is enough to control it while you play on the keyboard using more or less power) SO HO TO EVOKE IT PROPERELY if you build a multi kontakt template. You need to use a switch to evoke the LegatoPerformance,
