What is UACC and how do I use it?

Last updated:

Universal Articulation Controller Channel or UACC is a standardised way of switching articulations that was introduced with BML Sable and is included in every library since. 

Instead of using key switches to change from one articulation to another (which takes up precious keyboard space!) you can change to a particular articulation by setting MIDI CC#32 to a value a corresponding value. Below is a table of the various articulations and their corresponding value.

Say for example that you are using Spitfire Chamber Strings, a - Violins 1.nki and wanted to access the pizzicato articulation, you simply set CC#32 to the value 56. One limitation of UACC is that you can only select one articulation at a time so cannot layer articulations. To layer articulations the default key switches or UACC KS should be used. 

To use UACC instead of key switching first you must lock articulations to UACC. Using the Chamber Strings example again, first you must open the expert view by clicking the small black spanner icon (Screen_Shot_2017-05-15_at_15.13.35.png)

Next you simply click the small padlock that has now appeared next to the articulations and choose lock to UACC from the dropdown menu that appears as shown below:

Now sending the right value from CC#32 will select the articulations. If you are in doubt about which value to use clicking on an articulation whilst locked to UACC will display the UACC value needed as shown:

    why dont you just release a proper manual for the libraries?

    Hi Stefan, many of our libraries do have manuals which you can find in the "Key Stats" on their product page and we are always adding more manuals. If you cannot find the manual for your library please reach out to us on support and we'll be happy to help.

    What would be really great is if someone could put together a Cubase expression map that has all these expressions....

    @Sandy. I apologize that I did not knew that. thanks for clarifying that.

    @Alex. I also had that wish but then I found it better working with single instrument files and not using Keyswitches at all. Better and faster workflow

    Hi Alex

    We are planning a similar article soon for Cubase expression maps after some testing. I the meantime if you need any assistance setting up an expression map please reach out to our support team and we can offer advice.

    Thanks

    @Sandy,
    At the very end of the tut. above we see a yellow box that says
    "Pizzicato UACC CC#56"
    That seems to imply using a CC# other than CC#32.

    Would it be correct to assume that what that box actually means is
    CC#32 with a *value* of 56?
    Thanks!

    Hi Steve

    That's correct, as stated in the text above that image, this is the value of CC#32 that is displayed in the sidebar "UACC CC#56" essentially means MIDI CC#32 with a value of 56.

    Thanks

    Hi Alex, yes the article I mentioned previously was published here https://spitfireaudio.zendesk.com/hc/en-us/articles/360006347473-Using-Expression-Maps-with-UACC

    Thanks

    My confusion is in actual use. If I pull up the Spitfire Chamber Strings, a - Violins 1.nki patch.... If I'm using OSC, and using your OSC UACC KS template... there are all sorts of artics that are not in this instrument... so in order to switch artics and know what I'm doing, I have to have the Kontakt window open. I could as easily click with a mouse. Using OSC, how do I know which artics are available for a particular instrument? 

    I assume you have to create a custom layout

    The simplest solution ultimately was to use the large generic template, then copy and paste buttons etc into a custom template for groups of instruments like Chamber Strings main patches. I was resisting but it ended up not taking that long. You can also just look up the CC numbers and create new buttons. Once you get into it and do a couple it goes very fast!

    Thanks Mark. I found some touschosc layouts for other libraries as well so it's indeed just defining something that works out best for a specific library. ;)
