Sampler Loop Start / End Point - change with sliders?

[DanH]

@Christoph-Hart I saw some code from a thread recently which looks like it could be used to control the Sampler Loop point from sliders - is this possible? I'm trying to link Sampler1.LoopEnd to a knob callback (unsuccessfully!). Loop on / off would be great as well. Here's the code below:

/** Select all samples in the current samplemap
    ".*" is Regex and means everything.
*/
const var allSamples = Sampler.createSelection(".*");

/** You'll get an array of all samples, which you can iterate */
for(s in allSamples)
{
    /** Just multiply all sample properties with 2 */
    s.set(Sampler.LoopStart, parseInt(s.get(Sampler.LoopStart)) * 2);
    s.set(Sampler.LoopEnd, parseInt(s.get(Sampler.LoopEnd)) * 2);
    s.set(Sampler.SampleEnd, parseInt(s.get(Sampler.SampleEnd)) * 2);
}

/** This needs to be called after a sample manipulation op
    in order to refresh the UI. */
Sampler.refreshInterface();

@Christoph-Hart Whadayathink?!

It might work, although you need to be aware that changing the loop points will kill all voices and cause a streaming buffer refresh (because the loop point might intersect with the preload buffer range or other edge cases), so it's not something that you could automate as musical parameter.

@Christoph-Hart Ok that's encouraging...

Any clues to how I'd write a callback would be very welcome :)

@DanH said in Sampler Loop Start / End Point - change with sliders?:

s.set(Sampler.LoopStart, parseInt(s.get(Sampler.LoopStart)) * 2);
s.set(Sampler.LoopEnd, parseInt(s.get(Sampler.LoopEnd)) * 2);
s.set(Sampler.SampleEnd, parseInt(s.get(Sampler.SampleEnd)) * 2);

you probably want to think about what you are doing here:

    s.set(Sampler.SampleEnd, parseInt(s.get(Sampler.SampleEnd)) * 2);

essentially :
"please set the end of the sample to 2 x the length of the sample"

inline function onKnob1Control(component, value)
{
    for(s in Sampler1.createSelection(".*"))
    {
        local l = parseInt(s.get(Sampler.SampleEnd));
        s.set(Sampler.LoopEnd, value * l);
    }
};

Content.getComponent("Knob1").setControlCallback(onKnob1Control);

const var Sampler1 = Synth.getSampler("Sampler1");

@Christoph-Hart Thank you very much, there's no way in a million years I was going to get that lol!
