@ALBERTODELRIO I remember having this issue when first learning HISE…as @d-healey stated samples and presets aren’t a directly connected system….if I had to guess you’re probably loading up a set of samples and then creating a preset based on that sample…then loading up another sample map then creating a preset based on that…the samplemap system works in an alphabetical order…so if I create a sample map and call it “beta” then create a preset called “preset 1”…then I create another sample map and call it “alpha” and then create a preset called “preset 2” when I click on the preset 1 the “alpha” samplemap will probably load cause of the hierarchical structure…it’s a bit offsetting when you are just getting going…but I’ve found it a best practice to load up all of your samplemaps first for your project and then create presets based off of those…
