Truncate a sample via scripting

[blezzbeats]

Is it possible to truncate a sample from the set start end end points of a samplemap via scripting?

ok so I think you need to look at set and get for the Sampler, and apply it to each zone you want

// get the zones...
myZones = mySampler.createSelection(".*");  // <-- you get an array of zones

// an example get
myStart = myZones[aZoneNumber].get(mySampler.SampleStart);

//an example set
myZones[aZoneNumber].set(mySampler.SampleStart, aStartValue);
myZones[aZoneNumber].set(mySampler.SampleEnd, anEndValue);

@Lindon Thanks, that does work fine for updating the start and end points but what I'm really looking for is if I'm able to take a sample and destructively truncate it.

So I'm guessing after this step - either remove anything before and after the start/end or copy the active range and make a new sample by passing an array of samples with only that limited range to base64 and back to a new sample map.

The reason is I want to be able to use the AudioWaveform and select a smaller range from a longer sample, and have it display exactly that range so it covers the whole component if that makes sense.

Having a look at this for an alternative solution:

well a couple of observations:

It seems you want HISE to offer you a set of Audio editor-like functions - I cant see that ever happening.

But clearly you could redrawn your own waveform (for a custom made AudioWaveform) and scale as required.

@Lindon No and yes lol, the main objective is to crop the view to cover the start/end point selection and I thought that would be the simplest way if possible, because what else is it gonna display. But this looks like a good start, just gotta figure out how to calculate the zoom level and position based on that and update it automatically on changing start/end points with the AudioWaveform.
