      Where are you putting this code?

      ExpansionSelector.setValue(1); // Sets to first entry (1-based)
      ExpansionSelector.changed();

        This comes after things like expansion handler, samplers, and their associated combo boxes. Though I think it's worth mentioning that even with this code commented out entirely, the issue remains.

          @Elezeid If that code is within on init then it won't do anything so you can remove it.

          Make a new minimal project with two expansions and a factory preset. Use a waveform generator rather than a sampler, and something visual on the interface, like a knob, so you can tell exactly which expansion/preset has loaded.

          See if you can recreate the problem with that scenario. If you can then you can send me that minimal project and I can take a look.

            Thanks David. I'm happy to do this, though I want to point out that the issue that I'm having is very specific to samples. My plugin is a rompler essentially, and the trouble is that the wrong samplemaps are loading in. Without a sampler, there would be no way for me to debug this.

              @Elezeid Oh so everything else in the preset is loaded correctly, it's just the samples that aren't?

                Yes exactly, the combo boxes that populate with the samplemaps are showing the correct content, but the audio remains factory unless you choose a preset from the expansion - even if the current preset is already from the expansion. It's like the plugin can't access samplemaps from expansions until the user manually selects them.

                So in short, it looks like this:

                1. User chooses a preset from an expansion
                2. Expansion loads and works correctly (including samples/samplemaps)
                3. User saves their project and closes the DAW
                4. User opens the DAW and loads the same project
                5. Plugin loads all parameters correctly on the interface, including expansion sample maps
                6. Audio produced by plugin is from Factory sample maps
                7. User clicks on the preset that is already currently selected
                8. Correct samples now play (rinse and repeat)

                  @Elezeid Ok, in that case make the minimal project as above, but with a sampler and a couple of sample maps to demonstrate the issue.

                    Thanks for your willingness to help David. I just made a dummy project for testing. Here's what happened:

                    Factory: 2 presets and 2 sample maps
                    Expansion 1: 2 presets and 2 sample maps
                    Expansion 2: 2 presets and 2 sample maps

                    Exported to VST3, created a DAW project and...

                    No issue. The problem is totally absent! I'm not completely certain as to why, but I suspect maybe it has something to do with where the code is in the hierarchy.

                    Thanks for guiding me through this, I think I have the necessary tools to get across the finish line without pestering you any further! Just in case, here is the code for the dummy plugin.

                    Content.getComponent("knbDum").setControlCallback(onknbDumControl);
                    
                    // The sampler references
                    const var Sampler1 = Synth.getSampler("Sampler1");
                    
                    // The ComboBoxes for Expansions
                    const var ExpansionSelector = Content.getComponent("ExpansionSelector");
                    
                    // The ComboBoxes for SampleMaps
                    const var cmbSampleMap = Content.getComponent("cmbSampleMap");
                    
                    // Expansions Handler Create
                    const var expHandler = Engine.createExpansionHandler();
                    
                    // Expansion Types Allowed
                    expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                                         expHandler.Intermediate, 
                                                         expHandler.Encrypted]);
                                                         
                    // Expansions list retrieve
                    const var expansionList = expHandler.getExpansionList();
                    
                    
                    // Extract names of the expansions
                    const var expansionNames = [];
                    
                    // Add “Factory Content” as the first option
                    expansionNames.push("Factory Content");
                    
                    // Add all available expansions
                    for (e in expansionList)
                    {
                        expansionNames.push(e.getProperties().Name);
                    }
                    
                    // Fill the Expansion ComboBox
                    ExpansionSelector.set("items", expansionNames.join("\n"));

                    const var currentExpansion = -1;
                    
                    // Help function for updating all SampleMap ComboBoxes
                    inline function updateAllSampleMapComboBoxes()

                        {

                        }
                        else if (actualValue > 0 && actualValue <= expansionList.length)
                        {
                            // For expansion, load the SampleMaps of the selected expansion
                            local exp = expansionList[actualValue - 1]; // -1 because 0-based index

                        }
                    }

                        }
                    }

                    // Initialize with Factory Content
                    //ExpansionSelector.setValue(1); // Sets to first entry (1-based)
                    //ExpansionSelector.changed();
                    

                    Thanks again! If I run into more hurdles with this issue I'll return to this thread.

                      @Elezeid Nice! This is why I like minimal projects, they help to quickly find if the issue is the project or something more general to HISE. Good luck.

                        In case anyone else should ever run into this problem here is the solution (I'm kicking myself).

                        The Expansion Selector has to be higher than the sample map selector in the UI tree.
                        That's it.

                        That's why the minimal project worked, and that change seems to have completely fixed it in my main project.

                        Thanks again for all your help. Hopefully this will help someone in the future!
