I am having a little trouble though after I’ve implemented the code. The Sample Selector works as it should now. But I HALion has a crash now if I touch any of the parameters on the macro page that link to the FX in Layer 1(the layer that is being swapped out in the Sample Selector). Each Layer that is being swapped out via the Sample Selector is identical to each other, other than the fact that they are different samples (named the same though). Is this something you might know the cause of?
When you load a new layer preset for Halion it’s a new object. So your macro page is pointing to something that has been removed and replaced by something else. This could cause a conflict. But I think it shouldn’t crash though so you might want to report that to issues forum. It does crash here as well.
To work around this I would move the FX to Program Bus. Especially if you plan to use the same FX for all layer presets. As the Program Bus doesn’t change it shouldn’t cause problems.
