      @d-healey yeah - but this is my exact problem - I would need to ship all the audio files as compressed audio with their associated sample maps(500 sample maps) AND ship all the audio(wav files) again as load-able into an audioSampleProcessor. These would need to be pooled so I think this number would break the heap space limits in the windows compiler.

      Meanwhile the sampler already has this data and can display it how I'd like - but I cant get to it (Sampler>Sample Editor)

        @Lindon Ah I see, I was thinking the loop player could load from sample maps. @Christoph-Hart - feature request :)

          Secret tip of the day: use the sampleIndex property if you want to display samples from a samplemap in the audiowaveform.

          Load any samplemap into the Sampler1, then press Refresh and you'll see the exact sample you've selected.

            @Christoph-Hart well yes, and no.....

            When I make a sample map and create a ch1 file for it and then load this (ready to ship) sample map - the audioWavewForm doesnt refresh at all... :-(

              Have you selected a sample in the combobox?

                  OK so for those of us trying to use this in any practical scenario - there's a couple of gotchas.....

                  So assuming a scenario where you want to load a sample map and display the audio at the same index position in all cases, so for example you have a set of hundreds of drum sample maps, each with just one wav file (at index zero obviously..).

                  So you swap out and load the new sample map and say:

                  AudioWaveform1.set("sampleIndex", 0);
                  

                  and you will (sadly) discover your AudioWaveform will not display the new wav file...

                  The only way around this that I've found (and its sorta ugly) is to:

                  • set the AudioWaveform to some other index position (even if theres no file at that position) e.g.
                  AudioWaveform1.set("sampleIndex", 1);
                  
                  • wait for it to set itself up...(use a timer) and then reapply:
                  AudioWaveform1.set("sampleIndex", 0);
                  

                  You cannot do this:

                  AudioWaveform1.set("sampleIndex", 1);
                  AudioWaveform1.set("sampleIndex", 0);
                  

                  As again it fails to work

                  Here's my snippet of this cough "solution" at work... if any one has a better way of doing this please let me know...

                      @Lindon I don't know much on this side.
                      But maybe Engine.getPreloadProgress() can help you?

                        @ustk - thanks - I looked at the API - just one question "the progress of what?"

                            @ustk lol - yes - the preload progress of what? The Sample Map? The AudioWaveForm ? my washingmachine?

                            and once i know what this is Im not sure how this helps me in any real way....

                            Actually this is a bit dis-ingenuouse of me..sorry. Yeah waiting for the sample map to load might be what I need - but I think what we need here... but its working right now so once I need to laod a bigger sample map and thus need some sort of async. call back method I think I might ask for that...

                            Hey @Christoph-Hart - how about it:

                            on async(event)

                            (just half joking here...)

                              @Lindon Apparently, it's the progress when loading samplemaps (maybe just audio samples too? don't know...) Sorry man that's all I know

                                @ustk Maybe just to replace your timer with something cleaner... Again, that's a side of Hise I don't really know...
