Math.randInt / Stop duplicate returns.

[Chazrox]

I have a randomizer button working. I notice that sometimes certain parameters dont change. Is that because Math.randInt is returning a duplicate number? Is there a formula to ensure that every integer returned is not the same as the last?

Some of my groups have smaller numbers like 12 items so I suspect the Math is just returning duplicates sometimes.

Math.randInt is returning a duplicate number?

It's returning a random number, which might be the same as the previous number.

The usual way to handle this is to store the generated value in a variable, then generate random numbers in a while loop until you get one that isn't the same as the previous value.

It's also possible to do this without loops but the maths is a little more in depth. Here's an example of how to do it in Kontakt (KSP) for generating a non-repeating round robin - https://www.orangetreesamples.com/blog/scripting-nonrepeating-roundrobin

And here's me demonstrating how to use the principles of that KSP script in HISE

@d-healey Sweet! I'll watch this now. Hope you're having a great day brother! Thanks
