I created a virtual instrument in Halion 6. Currently, the Macro Page has a static background image.
I want to change the background image based on the value of the two basic control knobs of my UI. I imported Bitmaps for all possible combinations of the two knobs into the resources and now want to access them via lua script.
How can this be done?
First you need to create a stack for the background image. Duplicate the image control as many times as you need. Connect each of the duplicates to different bitmap image. Then you need a parameter that will control the stack. It can be a UI variable or any other parameter (integer).
You need to create callbacks for those two knobs and work out the logic of switching the background. Something like - if knob 1 is bigger than 50 and knob 2 is 0 then background stack = 1
