      Hello. So I just created 8 expansion which each has about 80 sample maps. I have been working on this project for over a year. so i have about 700 hr1 sample. when switching to the extension, I had to modify the preset files manually (right click, notepad ....) so that each preset correspond to its successful sample map.mission. however I have a few small bugs sometimes. when i load a preset, it will release a sample map which has nothing to do with the preset. I just have to load 2 3 different presets and everything goes back to normal. do you think there may be conflicts somewhere? moreover, since the last scriptnode verison, the next / prev buttons of the presets cause hise to crash.

        @Lindon said in Expansion Tutorial:

        Success!!!

        • Yep all you need do is refer to the sample map in the expansion and it will load - even if other samplers in your project are loaded with sample maps from somewhere else...

        Cool.

        Forwards!!!

        I'm exploring this too. So when you say "refer to the sample map in the expansion", do you mean you use the file system API to get them?
        I have a similar use case to the one you explained above. I just need to provide new samples/samplemaps/presets and use them at the same time as the factory ones.

          It's just a different "wildcard" in the reference. So for factory content you use {PROJECT_FOLDER}MySampleMap, and for a sample map in the expansion you just load {EXP::MyExpansion}MySampleMap and the system will detect magically that this is a samplemap from the expansion MyExpansion and search its content for the samplemap. You can load multiple assets from different expansions at the same time as well as mix it with factory content.

          What might be a little bit confusing is that there is an additional concept of an "active" expansion. That means as soon as you load a user preset from an expansion (or call ExpansionHandler.setCurrentExpansion() manually), the expansion system will set this expansion to be "active" and there can only be one "active" expansion at the same time. This doesn't have any impact on the availability of the content of other expansions, it just gives you the option to do certain stuff like swapping the background image depending on the current expansion.

            @Christoph-Hart Oh that's much clearer, especially about the active expansion thing, I thought it was much more intrusive but it's in fact just a state info.
            So I imagine importSamples() works with expansions too? Like importing an expansion sample into a factory sample map right?

              Well that won't work unfortunately. A sample outside of the project's sample folder (or the expansion's subfolder) will not be resolved using the wildcard but as absolute path.

              I'm afraid your plan of swapping samples inside a samplemap reveal a blind spot in the sample management system which takes samplemaps as somewhat static entities for granted and for the sake of future-proofness I would try to think of a solution that doesn't change samplemaps dynamically.

                @Christoph-Hart Ouch, that one hurts... So what would be the best solution in my case:
                I am using sample maps with 4 RRgroups (with group XFade)
                I need to replace any of the samples in a RRgroup with any other sample (factory or expansion)
                Of course, I need the user to be able to save all of that in presets...

                  @Christoph-Hart Oh I might have explained badly since I don't want to import user samples from anywhere, but only from expansion/factory sample maps... That'll work using the corresponding wildcards right?

                    @ustk You can only load samples from one expansion + factory at a time.

                      So everything's accessible apparently

                        Yes that kind of layout is the most difficult to achieve because it‘s directly in the middle of loop players and samplers. I would suggest 4 samplers instead of 4 RR groups.

                          Whilst Cristoph says...

                          "You can load multiple assets from different expansions at the same time as well as mix it with factory content."

                          -- so this first statement is wrong then ? I can load any sample map from any expansion - so I have 4 samplers I load sampler 1 with a Factory sample map, Sampler 2 with a sample map from Expansion A, Sampler 3 with a sample map from Expansion B, and Sampler 4 with a sample map from expansion C?? Right?

                          Please say yes - or its 3 months of work down the drain...

                            @Christoph-Hart 4 Samplers... I intend to have 4 to 6 voices so it makes it 16 to 24 samplers in total, which complicates too much the modulation. Essentially since I'm relying on group XFade, pitch, and gain modulation at the same time...

                              @Lindon I think yes, but you have to switch expansions between loading each sample map.

                              set expansion 1 = current, load a sample map from expansion 1
                              set epxansion 2 = current, load a sample map from expansion 2
                              etc.

                              I don't think changing expansions clears out currently loaded sample maps but it's possible it affects their sample references.

                                @Lindon You can I think, the expansion tutorial project seems to work this way
                                @d-healey I don't think "switch" is the right term since you gather all expansions at once, it is just a matter of selecting which one you choose to load a sample map. Christoph said (if I understood well) the active status of an expansion is just here so you can decide the behavior of your plugin based on that info. It doesn't restrict you to use any of those at the same time, to me it is just an info or status.

                                  Nope, that's not the case. It's like Lindon wants it to be, you can load any combination of expansion assets everytime without bothering about an active expansion (and I don't think loading an samplemap from an expansion switches the "active" expansion, but I'm not 100% sure though :)).

                                    @Christoph-Hart Oh cool, so as long as you prefix the expansion map name with {EXP::MyExpansion} and replace MyExpansion with the name of the expansion it should work?

                                            Does this fix the issue of the end user opening a saved project in the daw, and correct expansion presets will load that the user has saved? Been my issue the whole time
