@d-healey Great video was truly helpful!

@dustbro Thanks! I watched it and now it makes sense.

Backtick is the name of that symbol.

@jssrecording Just to clarify our conversation for anyone else. I update my code in the onNoteOn to this.

        if (Message.getNoteNumber() == 48) {
        
            Message.setGain(volumeSlider1.getValue());
    
         }

onInit

//volumeSlider1
const var volumeSlider1 = Content.getComponent("volumeSlider1");

@jssrecording It works @d-healey thank you! Also changed my slider to decibels. Thanks my friend! BTW you should create a Udemy course on Hise. You're extremely knowledgable.

@d-healey Ha ha oops! That's my mistake Setting my constant to the init now.
