Samplers as round robins?

tomekslesicki

Ok, another RR related post from me :-) I'd like to script something that would cycle the notes between three samplers. How would you approach this?

d.healey

What will the group setup be for each sampler?

tomekslesicki

Each has it's own RR groups and different velocities, too. Ideally, I'd like to be able to turn this system on and off via a button on the interface so all samplers could either play at once or cycle.

d.healey

So let's say each sampler has 5 round robin groups. Do you want all of the samplers to play group 1 then 2 then 3, etc. at the same time. Or do you want sampler 1 group 1 followed by sampler 2 group 1, etc. or do you want sampler 1 group1, sampler 1 group 2... etc? :)

Christoph Hart

Try a MidiChannelFilter in each processor and then Message.setChannel(roundRobinIndex) in your top script.

tomekslesicki

@Christoph-Hart I'll try that, thanks!

@d-healey said in Samplers as round robins?:

I was thinking:

Sampler 1, group 1
Sampler 2, group 1
Sampler 3, group 1

Sampler 1, group 2
Sampler 2, group 2

And so on :)

d.healey

@tomekslesicki I think Christoph's solution should do what you want then.

Christoph Hart

Yupp, there you go:

The problem when implementing this is that you need to take care of the note offs. I've written a helper "class" that lets you push and pop any kind of value using the event id as hash key so it will also work with overlapping notes.

EDIT: Fixed the MIDI channel filter settings so that it actually works :)

tomekslesicki

Awesome, thanks!

tomekslesicki

Ok, this works great but there's one thing I'd like to implement, and that is MPE. Would it be possible for the three samplers to still support that even with the filter rr script?

Christoph Hart

Yeah, you're right, this won't work with MPE then, as it needs the channel info from the original event.

However I just thought of a much more simple solution: just use the MidiMuter module:

You don't need to take care of the note off events here because that will be handled by the module itself (as long as you enable Fix Stuck Notes).

tomekslesicki

Nice! Now one last thing - what if I want to have 6 samplers playing in each RR cycle?

So:

RR1: Sampler1, Sampler2, Sampler3,Sampler4,Sampler5,Sampler6
RR2: Sampler7,Sampler8,Sampler9,Sampler10,Sampler11,Sampler12
RR3: Sampler13,Sampler14,Sampler15,Sampler16,Sampler17,Sampler18

I was able to achieve that with the filters and I'm sure it's doable with the logic here but I always sucked at maths ;-)

ustk

@tomekslesicki You can put them in 3 containers

tomekslesicki

Nice idea! Can I put the samplers into containers without copy-paste? It changes names of the modulators and I have quite a few of them...

tomekslesicki

This post is deleted!

Ok, I've tried to make this like that:

On init:

const var muters_a = [    Synth.getMidiProcessor("MidiMuter1"),Synth.getMidiProcessor("MidiMuter2"),Synth.getMidiProcessor("MidiMuter3"),Synth.getMidiProcessor("MidiMuter4"),Synth.getMidiProcessor("MidiMuter5"),Synth.getMidiProcessor("MidiMuter6")
                     ];
                     
const var muters_b = [    Synth.getMidiProcessor("MidiMuter7"),Synth.getMidiProcessor("MidiMuter8"),Synth.getMidiProcessor("MidiMuter9"),Synth.getMidiProcessor("MidiMuter10"),Synth.getMidiProcessor("MidiMuter11"),Synth.getMidiProcessor("MidiMuter12")
                     ];
                     
const var muters_c = [    Synth.getMidiProcessor("MidiMuter13"),Synth.getMidiProcessor("MidiMuter14"),Synth.getMidiProcessor("MidiMuter15"),Synth.getMidiProcessor("MidiMuter16"),Synth.getMidiProcessor("MidiMuter17"),Synth.getMidiProcessor("MidiMuter18")
                     ];

const var muters = [    [muters_a],
                        [muters_b],
                        [muters_c]
                   ];
                     
                     
reg rrIndex = 0;

And note on:

function onNoteOn()
{
    local index = 0;
    
	for(m in muters)
    {
        m.setAttribute(0, rrIndex != index++);
    }
    
    rrIndex++;
    
    if(rrIndex == muters.length)
    rrIndex = 0;
}

But I'm getting this error:

onNoteOn() - Line 7, column 26: Unknown function 'setAttribute' {Q3ljbGVTY3JpcHR8b25Ob3RlT24oKXwxMDN8N3wyNg==}

Christoph Hart

You're wrapping the muterX arrays into an array again, so it doesn't reach the actual modules.

Try

const var muters = [    muters_a,
                        muters_b,
                        muters_c
                   ];

Christoph Hart

Oh and the onNoteOn callback is also wrong. You need a nested for loop (and make sure you don't increment the index in the most inner loop, but in the outer loop so it reflects the actual RR index.

@Christoph-Hart I think I understood half of this sentence :D
