Multichannel Routing issue

Dan Korneff

@christoph-hart thanks for the info! Currently researching debugging.
On another note, did you try the test I recreated on your rig?

Make new project
add 2 samplers
route one to 1+2 master chain , and the other to 3+4 master chain
in master container, set number of channels to 4
route container master chains 1-4 to HISE out 1-4

In HISE it functions as expected. Once it's exported to VST, both samplers play out of 1-2

And then the JUCE VST plugin host crashes.

I also forgot to mention that when I compile the plugin, I get an error:

the pictures shown is inside the HISE standalone, yes.

but compiled this as VST is the same thing.
so tomorrow i will show you the result as VST.

But maybe you will work with the standalone HISE, instead of vst one to create. VST one is for me for creating a player and load libraries in it. but maybe i'm wrong.
but maybe my standalone HISE and compiled VST works ... maybe ...

see it tommorrow ( French time clock). tonight is for my family.

Christoph example works. my project (and pictures above) works. it's just to help you.

for finish: don't matter yellow lines in compiling. No matter. RED lines are another story. 100 % of time a wrong project/settings.

try standalone HISE instead of VST; because first you don't have to open DAW or something else to work. Just HISE.

Quicker, simplier. Never worked with other thing than standalone one.

what daw do you use ?
i use a lot of daws (reaper, bitwig, sonar, live and studio one)
but i prfer studio one (for multichannels) it's easy to know if it works or not.

tomorrow i will make a tuto to show this (HISE standalone, compiling, testing in S1) to see what wrong in your case

Dan Korneff

@staiff Thanks for checking it out. AFAIK the HISE plugin is the only multichannel version available. I can't create VSTi's that have multiple outputs on the standalone version.

I'm using Cubase and Reaper over here.

I'd love to! @Christoph-Hart Hurry up and get multichannel in standalone HISE ;)

staiff

the pics i put above is made with standalone. so it's possible via standalone. Think it's possible to test it in reaper, but honesty i just use reaper to test the plugin because if reaper reject it, your plugin never works ! Reaper is powerful for that: a best tester for plugin stability. but for puting FX in bus, testing multichannel i really don't know how ... for me studio One is easier .... but because i use a lot S1 for composing.

maybe have no time tomorrow ( but will have the time). in the worse case i'll make it Monday morning. As you live in NY, i will make tuto when you sleep and will be available at your wake up, for coffee + tuto ;)

For info i actually working on a drum rompler (Simmons) with multi sampler (as seen on pics) separates kick, snare, hat, etc. ... and multi-out for each samplers.

all in HISE SA. speedy compiled in VST 64 windows tonight and it works.

I think maybe there's miscommunication on the term "multichannel"? The standalone version doesn't allow more than 2 physical outputs from HISE in your main container.
Am I not understanding that correctly?
And HISE multichannel (only available in plugin format) allows up to 16 physical output in the main container.

I can't wait to check out the VST you're designing! Sounds awesome

@staiff said in Multichannel Routing issue:

I think that's the difference. I'm not using multiple outputs from each sampler, I'm using physical outputs from HISE.

Dan Korneff

I'm circling the wagons around the issue causing my plugin to fail. It has something to do with:

amount of samplers in a container
multiple samples with different velocity ranges in a single sampler

Almost figured it out

Dan Korneff

@Christoph-Hart I think I got it. I can't have more than 1 midi note occupied with RR samples in a single sampler. The second that I have 2 RR instruments in the same sampler, I get a crash.

Christoph Hart

That is weird. Can you send me the patch and the samples so I can try to reproduce it?

Dan Korneff

unfortunately, It's not the only cure... still having issues which might be container related.
Sending you the patch now

oooooooooooooookaaaaaaaaaaaaaaaayyyyyyyyyyyyyyyyyyy ! :D
miscommunication for sure !

as Christoph already said =
HISE Standalone (and maybe VST, i don't know, i'm not using it) has only 2 ouputs (1+2) !

So when i create multi out project in Hise, of course i only have a single stereo output !
i must compile it (as VST or Standalone or else) for testing the multi-out.

during the Hise process you can't really test it. But as i know the Christoph's code/example works well i create without doubt in HISE.
after that when compiling it and test it as WIN VSTi 64bits and put it in Studio One plugin = i have multi output !

That's why Christoph put in the example the "ok, error" part of code = just to show you that when you don't have multi outputs (like in HISE) = it says "error" and put all multi out in the single 1+2 (stereo main) outputs ! :D

alaways need a video tuto now ? ;)

@Christoph-Hart After testing, it appears random what compiles properly and what doesn't. The only consistent thing is compiling any project containing more than one sampler is like rolling the dice.
Could this be an issue with Visual Studio 2017?? or something else...
I should also add that this is for compiling VST. Sandalone works properly.

Dan Korneff

@Christoph-Hart I've been tinkering with this all morning. I can isolate the problem 100% to the audio files. I compiled a VST of my project, moved it to another computer (without the samples) and it loaded fine! The second that I locate the sample folder in the plug, it crashes all hosts. if I remove the sample folder, it opens fine again. I've gone thru each of the sample audio files, and I can't find anything wrong with them.

Dan Korneff

Debugging in Visual Studio. I'm getting somewhere I think.
PluginHost throws an exception on jassertfalse;

					if (!lock)
						jassertfalse;

		}

Once I skip past that breakpoint, the debug version of the plugin loads

@staiff

thanks for they nice Video staiff.

staiff

thanks.

if you encounter an error (or crash) of the plugin =
in PC : erase/delete the: user/appdata/roaming/you/Pluginfolder and reload it.
it will ask again the sample location and all will goes ok again ;)

yes, i know ... boring ... but it works !

For MAC i don't know but the same thing as appdata/roaming for PC.

@staiff thank you so much, this tutorial is very helpful.
