<![CDATA[No Multichannel output]]>Ahoi,

I have setup 16 channels and routed each sound of my drum plugin to a channel
it looks right in HISE, but when i compile the project and run the plugin in a DAW
even with all multi outputs switched on it still just plays through the main 1+2

what am I missing?

are there any tutorials or documentation on how to handle multichannel?

I fiddled about a little and this script finally worked:

const var MorphDrum = Synth.getChildSynth("MorphDrum");
const var matrix = MorphDrum.getRoutingMatrix();

matrix.addConnection(0,0);
matrix.addConnection(1,1);
matrix.addConnection(2,2);
matrix.addConnection(3,3);
matrix.addConnection(4,4);
matrix.addConnection(5,5);
matrix.addConnection(6,6);
matrix.addConnection(7,7);
matrix.addConnection(8,8);
...

apparently I was quite close already, but it does indeed need the script to do the addConnection and won't work without. Thanks for the help! I would never have figured that out on my own

const var numBIGDRUMMYVST = Synth.getRoutingMatrix("BIG DRUMMY VST");

numBIGDRUMMYVST.setNumChannels(24);

that changes nothing either ;/

Do you have this? Just double checking...

I have this set for my Master container,

const var numBIGDRUMMYVST = Synth.getRoutingMatrix("BIG DRUMMY VST");

numBIGDRUMMYVST.setNumChannels(24);

Routing for first 3 samplers in "multi out" mode. See kick starting at 3/4 for me.

is the structure a problem`? they are all in a container...

//I think this is what Dave was talking about....

Sampler1.asSampler().setUseStaticMatrix(true);
Sampler2.asSampler().setUseStaticMatrix(true);
Sampler3.asSampler().setUseStaticMatrix(true);
Sampler4.asSampler().setUseStaticMatrix(true);
Sampler5.asSampler().setUseStaticMatrix(true);
Sampler6.asSampler().setUseStaticMatrix(true);
Sampler7.asSampler().setUseStaticMatrix(true);
Sampler8.asSampler().setUseStaticMatrix(true);
Sampler9.asSampler().setUseStaticMatrix(true);

I think this is the missing part.

When you drop your plugin on a new track in DAW, you have to also create new audio tracks to receive the audio that you want to route out of your plugin. For each audio track, you should set the input to the outputs of your plugin. Make sure that whatever your daw requires you to click on your tracks to hear live input through your audio track is enabled for each track.

That's just for good measure. Its seems like you have it set up properly but you did say that all audio is coming out of 1-2, so that def says that it's not routing out properly. How are you scripting your routing changes? Is your plugin meant to load multi-out by default or are you allowing dynamic routing?

Just a thought...
Did you uncheck 'Force Stereo Output'?

Looks like you have NUM_MAX_CHANNELS set already since you have the extra channels showing in HISE....

Also,

I just checked my drum plugin, I started my kick chn. with 3/4, I can't remember exactly why I did it this way. Here's what I have.

Screenshot 2025-12-16 at 8.54.48 AM.png

in Ableton, I have "In" enabled on each auxilary track to be sure I can hear the chn input live during playback otherwise you will hear nothing.

I also have this on onInit script initializing the connections...

//! MASTER EQ ROUTING DEFAULTS

const var numMasterEQNew = Synth.getRoutingMatrix("MasterEQNew");

numMasterEQNew.addConnection(0, 0);
numMasterEQNew.addConnection(1, 1);
numMasterEQNew.addConnection(2, 2);
numMasterEQNew.addConnection(3, 3);
numMasterEQNew.addConnection(4, 4);
numMasterEQNew.addConnection(5, 5);
numMasterEQNew.addConnection(6, 6);
numMasterEQNew.addConnection(7, 7);
numMasterEQNew.addConnection(8, 8);
numMasterEQNew.addConnection(9, 9);
numMasterEQNew.addConnection(10, 10);
numMasterEQNew.addConnection(11, 11);

Not at my computer at the moment so can't check, but will later.

]]>https://forum.hise.audio/post/114463https://forum.hise.audio/post/114463Tue, 16 Dec 2025 15:38:25 GMT<![CDATA[Reply to No Multichannel output on Tue, 16 Dec 2025 15:35:56 GMT]]>@Chazrox i didnt understand any of the first sentence but as for the second, yes 1+2 is having all the content of the entire plugin, although in hise anything except the kick is routet to channels 3 and above

Also, good to check if you have monitoring enabled on each of these tracks. Im not sure what daw you're in but thats the normal flow for any daw w/ multi-channel plugin.

When you have multi-output mode on your plugin activated, what are you hearing from 1/2? Everything or a single sound?

I think you have to make the connections through scripting.

There's also a useful snippet in the docs: https://docs.hise.dev/scripting/scripting-api/routingmatrix/index.html
