        @Christoph-Hart Will that work if you've previously set the sample start or end to a range that isn't the sample's full length? I'm thinking you'd need to make sure they always started at the min/max you would ever need and then keep track of any changes you make after.

          I discovered this in the core HISE code getSampleLength() but it might serve a different purpose.

          That function is for audio processors, not for individual samples. Samples use properties with the .get command but sample length isn't an available property so it would need to be implemented.

            Ah yes, that makes sense. Thanks guys.

            @Christoph-Hart Yes that would do it, but would yield inaccurate results in the case that the user changes the sample start first.

            @d-healey Agreed. Sounds like I'll need to track all the sample lengths in an array the instant a sample map is loaded using the method @Christoph-Hart mentioned above.

            Appreciate the responses!

              Searching SampleEnd or SampleStart in the manual I don't come up with anything.
              How would you get those via script?

                These are the basics of setting sample properties programatically:

                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...

                However the API has been extended to support Javascript-style loops so I recommend using this syntax instead:

                for(s in Sampler.createSelection(".*"))
                    s.set(Sampler.SampleEnd, 12000);

                  That's what I was looking for, Thanks.

                    I just discovered you can set the SampleStart to a negative number and it will delay the start....
                    Would this be a wise thing to do?

                      @d-healey Do you know if there is a way to do this now? Just like you said the sample length is overwritten whenever SampleStart or SampleEnd is changed and I can't find a way to get at the original sample length. Even when loading custom samples I can't really figure out how to snatch it before initAfterSampleLoad() which is called every time the sample is updated.

                      I'm drawing on a panel on top of an AudioWaveform and need to find a way to calculate the relative position and size of the selected range within the total view. Resize the panel to only cover the selected range in other words.

                      Figured one way to do it was to work with the AudioWaveform, but getRangeStart() and getRangeEnd() return 0.

                        @audiolyf It's not something I've explored.
