Non Repeating Round Robin Help

[Casmat]

Hey guys!

I have this script "roundrobin1" in my HISE project:

oninit:

const var sampler0 = Synth.getSampler("sampler0");
sampler0.enableRoundRobin(true);

const var sampler1 = Synth.getSampler("sampler1");
sampler1.enableRoundRobin(true);

const var sampler2 = Synth.getSampler("sampler2");
sampler2.enableRoundRobin(true);

reg counter = 0;
reg lastCount = 0;

onnoteon:

function onNoteOn()
{
	counter = (lastCount - 1 + Math.randInt(2, 5)) % 5 /*round robins*/ ;
	Message.setVelocity(counter + 1);
	lastCount = counter;
}

I had followed David Healey's non repeating round robin video on YouTube, but when I use my three samplers, the round robins still go incrementally. Thanks!

@Casmat

sampler2.enableRoundRobin(true);

Needs to false, not true.

[Casmat]

@d-healey

changed it to false, but the round robin number doesn't change now in the sampler view

[d.healey]

@Casmat Have you mapped your RRs to velocity?

[Casmat]

@d-healey

no, i just jave them as regular RR groups from the filename token parser setup

[d.healey]

@Casmat Well I don't see anywhere in your script where you are changing the active group but I do see you changing the velocity.

[Casmat]

@d-healey

ahhh, how what would i replace to affect the rr groups?

[d.healey]

@Casmat You tell me how you think you do it and I'll nudge you towards the correct answer if you're drifting from it. If I just tell you the answer then you haven't really used your noodle.

[Casmat]

@d-healey
would we be using the setActiveGroup?

[d.healey]

@Casmat Yes, try it and see.

[Casmat]

@d-healey
the sampler still has no chamging rr groups, i changed Message.setVelocity to Sampler.setActiveGroups

Sampler.setActiveGroups won't work. You need to replace Sampler with the reference to the specific sampler you want to affect.

Are you wanting all samplers to changes to the same group at the same time, or do you want each one to change to a different random group?

[Casmat]

@d-healey
i would like each sampler to change to a different group

[d.healey]

@Casmat In that case you should use one RR script per sampler. Of course you don't want to re-write the same code 3 times, so this is where a reusable module is perfect.

This is what we did in the Hackspace course (I think it was in part 3).

[Casmat]

got it! thanks for clarifying!

[Casmat]

@d-healey
Just tried testing it and it seems to not work still. the RR groups in the sampler view don't seem to change number. this is what I have so far:

oninit:

const var sampler0 = Synth.getSampler("sampler0");
sampler0.enableRoundRobin(false);

reg counter = 0;
reg lastCount = 0;

onnoteon:

function onNoteOn()
{
	counter = (lastCount - 1 + Math.randInt(2, 5)) % 5 ;
	sampler0.setActiveGroup(counter + 1);
	lastCount = counter;
}

Here's the hise snippet as well:

@Casmat Your snippet works here, the groups change with each key press.

I noticed you are hardcoding the sampler reference which means you need three separate scripts. Try to avoid this. Instead, reuse the same script as I demonstrate in the Hackspace course.

The problem with writing 3 scripts that all do the same thing is it doesn't scale well and you give yourself additional code maintenance. Imagine you have a project with 10 samplers, now you have 10 separate RR scripts that all do the same thing except one line is different. Then you find a bug in the script, now you have to go through 10 scripts to fix the bug 10 times. It makes no sense to do that when you can write and maintain one script instead.

@d-healey

Hmm, that’s weird, it doesn’t seem to change on my end, I’ll try fiddling with it in the meantime and yes, I had the scripts all connected, I had just disconnected them to see if that would’ve fixed the problem. Thanks again for your help!

[Orvillain]

Hey, sorry for the necro bump. But if you've got say 7 RR groups... and for a particular velocity range there are only 6 samples..... is it possible to avoid the sampler triggering silence when it cycles around to the 7th group.

So for example:

RR1 - vel-range 60-70 - sample mapped
RR2 - vel-range 60-70 - sample mapped
RR3 - vel-range 60-70 - sample mapped
RR4 - vel-range 60-70 - sample mapped
RR5 - vel-range 60-70 - sample mapped
RR6 - vel-range 60-70 - sample mapped
RR7 - vel-range 60-70 - NO SAMPLE MAPPED

Currently you hit a note to trigger the sample 6 times in a row... you'll trigger RR1, 2, 3, 4, 5, 6... and then on the 7th it will attempt to trigger RR7.... and produce silence, because there isn't a sample there.

Any way around this?

Put some samples there - copy them from another group
