      @trillbilly I haven't got my head around it yet but I have a feeling it was my thread where you got this script and if it was I remember it has a few issues, not least that every sample length is different and will need to be parsed each time it's loaded etc etc. I'm not sure there's an effective solution right now available but I would be DELIGHTED to be proved wrong! :)

      @Lindon I seem to remember you might have been working on something related to this?

        @DanH Yes, I believe it was that thread.

        Detecting the Sample End is something I also posted about for this. @d-healey had pointed me to a thread about Regex that he said may be of some help.

        This is an advanced feature that I just implemented (and you need at least version 0.984 for this). You can now change the properties of individual sample so...

        Also, using the knobs makes the AudioWavform View a bit jumpy. Hard to get a precise location unless you drag the Sample Start/End points. This doesnt work for Loop Start/End points though.

        It does a decent job for what I can figure out.

            well Im not so sure how useful it is but ...
            essentially this:
            2245da6d-4d19-450f-ab06-d15417551f60-image.png

            ..which wants to set the sample length for each sample in the loaded map...heres the code I use...with a little description:

            postLoadZones = yourSampler.createSelection(".*");
            // this creates an array of all the zones (wav files) in the sampler
            
            		
            		// for all zones....
            		for (zi = 0 ; zi < postLoadZones.length; zi++)
            		{
            			//Console.print(" ========= zone:" + zi + " start is:" + segmentData[lsi].SampleStart + " end is:" + segmentData[lsi].SampleEnd);
            			postLoadZones[zi].set(theSamplers[postTargetSampler].SampleStart,YourStartValue);   // that sets the start
            			postLoadZones[zi].set(theSamplers[postTargetSampler].SampleEnd,YourEndValue); // that sets the end
            		}

              @trillbilly I remember now that you couldn't reliably save the presets using the current preset system. When you reload a sample map it reloads the start and end points of everything to what was saved in the sample map as opposed to what you saved in a preset via the ui.

                @DanH Ahhhh, that does pose a bigger issue then. Ive been stuck creating some MIDI Packs for my site. I've got a few hours now, I'll mess with it now.

                  @DanH Couldn't you reload the values after changing sample map?

                    @Lindon Awesome! Im going to try this out now.

                    Have you had an issue with what @DanH said regarding the Start/End times saving to what is set in the samplemap rather than the UI?

                      @DanH I've only saved a few demo presets but as of right now it all seems to be working as expected. I know you said "reliably", how often did it fail for you?

                      EDIT: Scratch that, I see what you're saying. It saves them but does not load them correctly all the time, at least on my end.

                        @d-healey Yeah I'm thinking of trying to do it in the preset handler post callback.

                            so this I think is probably the problem I ran into - it basically a timing issue - the sample map is not loaded instantly - so you are probably trying to set the start end values for zones not even loaded yet...and yes @DanH I ended up doing a o lot of this stuff in preset handler post callback

                              @Lindon Ahhh, that makes sense. Because if I click the same preset multiple times, the start/end values will eventually get to where they need to be.

                              So doing it in the Preset Handler Post Callback, Im having some newb issues.

                              Here is the code from documentation

                              UserPresetHandler.setPostCallback(var presetPostCallback)
                              

                              Im not understanding something because I get "Unknown function 'setPostCallback'" error. Here is my jumble.

                              const var samplestart = [Content.getComponent("SampleStart1"),
                                                       Content.getComponent("SampleStart2"),
                              		         Content.getComponent("SampleStart3"),
                              			 Content.getComponent("SampleStart4")];
                              
                              UserPresetHandler.setPostCallback(samplestart, presetPostCallback);
                              

                              Am I not calling for the variable correctly? Or the right variable? These are the knobs on my UI controlling Sample Start times.

                                @trillbilly You need to create a user preset handler first. const uph = Engine.createUserPresetHandler() then you can call the function on that object

                                uph.setPostCallback(function()
                                {
                                });
                                

                                UserPresetHandler.setPostCallback(samplestart, presetPostCallback);

                                If you take a look at the documentation again you'll see the setPostCallback function only takes one parameter, you've tried passing in two which won't work.

                                  @d-healey Ok, I get it to compile. But then when I use the function (in this case the sample start time) it then spits out the same "Uknown function 'setPostCallback" error.

                                  const var samplestart = [Content.getComponent("SampleStart1"),
                                                           Content.getComponent("SampleStart2"),
                                  		         Content.getComponent("SampleStart3"),
                                  			 Content.getComponent("SampleStart4")];
                                  
                                  const uph = Engine.createUserPresetHandler();
                                  					    
                                  
                                  uph.setPostCallback(function()
                                  {
                                  	UserPresetHandler.setPostCallback(samplestart);
                                  
                                  });

                                    @trillbilly It's late here so I'll give you an answer in the morning, but reread your code and look up each function you're using in the documentation in the meantime.

                                      @Lindon Thanks :) Can I ask what you did in the post callback? I'm simply grabbing the values of the loop start/end knobs and then loading those values back into those knobs. It works sometimes and not others, leading me to suspect timing issues (poss related to sample loading time?!)

                                          @DanH - what I did was I waited.... 2 seconds works here... so on preset postcallback I did the following:

                                          1. tried to set the sample start and ends...it probably wont have worked but hey - no loss to try..
                                          2. Started a timer on the panel its in (clearly the UI is visible otherwise we cant have selected a preset to load..)....so essentially this:
                                          Circle.sampleLoadTimer.startTimer(2000);
                                          

                                          in the timer... I did the following:

                                          1. stopped the timer...as we only need to do this timer activity once...
                                          2. reset the sample start and end times...as with luck the samples will actually now be loaded..

                                          You may be using bigger(or smaller) sample sets than me (its only 12 waves) so the timing might need to be different, and I checked my timing loading from an external USB 2 drive..(very slow)

                                          I am using a whole truckload of AudioWaveforms (I have 16 samplers) and I found I would need to "reset" these to show the new start and end values.. so I simply
                                          call:

                                          theAudioWaveForms[<someindex>].set("sampleIndex",<the zone index you want>);

                                            @Lindon thanks, timer seems to be the way. Although does this mean that the post callback is slightly flawed, in that it should probably wait until the samples have loaded before triggering @Christoph-Hart ?
