Voice Limit Count: scriptnode synths?

griffinboy

Sorry I'm struggling to find that in the docs! If you meant the javascript which I assumed you did rather than the c++

Unless you do mean the c++, so instead of using NV for the polydata, I just type in the desired number of voices?

or something like

template <int NV = 8>
    struct Granular_Synth_2 : public data::base
    {

( ^ Okay well this probably wasn't what you meant because it didn't work xD )

// maybe
PolyData<Voice, 8> voices;
// instead of?
PolyData<Voice, NV> voices;

^ hmm, doing this wasn't right either.

Maybe you were referring to the Hise UI scripting? I still couldn't find anything in the docs about it

The docs search is limited, I use github's search

@Christoph-Hart said in Voice Count: scriptnode synths?:

NUM_POLYPHONIC_VOICES

It's a pre-processor definition?

else
{
	// your handleVoiceLimit() function failed...
	jassertfalse;
}

mmmm.... I'm managing to do nothing but break things.

I'd like to be able to set a voice limit at compile time. It's all for efficiency reasons. If theres no overhead then I guess it doesn't matter, but I know that it makes a difference in the sampler so I wanted the same for my scriptnode synths.

I'm sorry to pester
But I'll have to ask you to elaborate / be specific

Christoph Hart

I'd like to be able to set a voice limit at compile time.

Yeah, just set NUM_POLYPHONIC_VOICES to whatever amount you want in the extra definitions of your project, it will be used globally for all sound generators, including your custom ones.

During development you should ensure that you compile HISE with the same value as you compile the DLL with, otherwise it'll be glitchy.

@Christoph-Hart

Ah, in the project like this?
I never knew this existed. I assume it will only take effect after compiling the whole plugin?

I initially rebuilt hise with the lower voice count pre-processor but that caused errors when I tried to play voices above that count. Perhaps this way will work.

Thanks for elaborating.

Christoph Hart

@griffinboy if both HISE and your dll are using the same value here it should work fine (and if you change the value in the HISE source code directly you don‘t have to do it here).

griffinboy

@Christoph-Hart

.dll ?

I have a feeling I still am missing a piece of information. But I'll see where this gets me. I got errors when I tried to build Hise with the pre-processor definition before. I'm going to try all of the different ways and see what works.

Christoph Hart

@griffinboy if you compile your effect to be loaded into HISE, it'll be a DLL that HISE loads and calls into for the processing. This DLL has to be compiled with the same NUM_POLYPHONIC_VOICES value or otherwise there will be a mismatch and glitches.

griffinboy

@Christoph-Hart

How do I set it for the DLL? Is it a case of:

template <int NV = 8>
    struct Granular_Synth_2 : public data::base
    {

in the c++ node?

Christoph Hart

@griffinboy no, use ExtraDefinitions NetworkDll in the project tab, or better, just change the number in the HISE source code directly and done (since you have to change it anyway to match).

griffinboy

@Christoph-Hart

Hi is there a specific place to do this in the source code? Just want to be sure, sorry for asking!

griffinboy

@griffinboy

Update*

Adding the preprocessor definition that Christoph mentions in this post

NUM_POLYPHONIC_VOICES=16

in every available preprocessor box (including the juicer file when building Hise from GitHub, and the project preprocessor boxes) seems to have worked.

Voice limit must be set to a power of 2, or you'll get an error.

griffinboy

@Christoph-Hart

Strangely, I seem to have broken this...
My voices are being limited and I can't set a new higher limit. I've tried sticking in

NUM_POLYPHONIC_VOICES=64

Into every box I set my eyes on (rebuilding new version of hise on new hard drive, sticking this definition everywhere, as well as in all the boxes in the project settings) but to no avail. The limit is still stuck at 8, which is an old limit I set when I made this thread.

Is there some way for me to change this limit?
I find it odd that it carries over even to fresh hise builds,
I'm thinking maybe the projects I created while the old limit was in practice, have been infected?

Or is there a place in the source that I need to set this up?

@griffinboy Have you checked the project's XML? Might be there...
How is a blank project reacting?

griffinboy

@ustk

yes! its in the project xml

<Processor Type="SynthChain" ID="Griffin_WT" Bypassed="0" Gain="1.0" Balance="0.0"
           VoiceLimit="16.0" KillFadeTime="20.0" IconColour="0" packageName=""
           BuildVersion="650">
