kyma•tweaky: How LoopWhenFrequencyChanges

Question (or Task)

I have a sample I want to loop seamlessly at a random frequency/pitch every time the sample loops again. So I use the SampleFileDuration? to generate a random number that I multiply by the frequency of my sample. But the duration (length) of my sample changes according to its frequency and so when it triggers the sample again with a different pitch, my sample has either already looped again or it's still playing...

In this example, I used SoundToGlobalControllers to generate the random duration scale factor and !Gate for the Sample.

The random duration scale factor is:

!Gate nextRandom abs

which gives a scale factor between 0 and 1. To get a scale factor between 0 and 2, you could instead use

!Gate nextRandom + 1

Instead of checking the Loop box, I generate a !Gate using:

('count.aif' sampleFileDuration * !DurScale) s tick

This generates a gate once every (scaled) duration of the sample.
