Problem with more than 1 instance of plugin

[ulrik]

I'm developing a 5 voice synth and testing it in Logic Pro X but as soon as I load more than 1 instance of the plugin all goes silent, the cpu is ok so that is not the problem.

I don't know where to start investigating why it's happening, I'll be most grateful for all help and tricks I can get.

This is the instrument, in short there is 10 Syntheziser Groups with 2 Generators in each
I have 5 Global Modulator containers, one for each voice, and 1 more Global Modulator container for all voices (Global)

For each voice I have:

• 1 LPF Effect with 12 different Modulators / Filter 2 x (2 LFOs MW, Vel, 2 Envelopes) that's 6 mods for freq modulation and 6 for resonance
• 1 Gain Effect also with 12 mods for Gain and Pan
• 4 mods for Detune and 4 mods for Spread
  and some more...

In Hise it works nicely, also in Logic but only with 1 instance

Thankful for all tips how to debug this, I don't know how to deal with it

@ulrik have you tried with another DAW ?

[ulrik]

@matt_sf yes I just tested in Reaper and it works with more instances

What does this mean, and how do I correct it?

NaNs found in buffer

@ulrik maybe this will help, I found this in the Juce forum :
https://forum.juce.com/t/pluginval-nans-found-in-buffer/39636/5
And in the thread there's a github page link which explain the procedure to debug an issue with pluginval :
https://github.com/Tracktion/pluginval/blob/develop/docs/Debugging a failed validation.md

[ulrik]

@matt_sf great, thank you very much!

[ulrik]

@ulrik still having problem with this
I think I've fixed the Nans in the pluginval, either it was because of 2 missing "breaks" in a switch statements or,
which I think is the real issue, the missing of isDefined(value) in several knob control callbacks (all knobs and buttons are panels)

I discovered in Logic this:

Ok it is successfully validated but the version check shows "invalid" ??

So I opened up 2 instruments "project_info.xml" files and compared them

Does these findings mean anything to the issue I'm having?

Not that I think it will fix this issue - but why are you using panels for controls and not LAF?

I need the contextual menu...

[ulrik]

@d-healey No thoughts about the issue? or about the difference between the 2 instruments and why Logic says "invalid" on version number?

Actually it would be nice to have the "menuItems" opportunity on sliders as well

If I did I would have mentioned it I don't do much stuff on MacOS and so far haven't run into any issues like this.

[ulrik]

@d-healey Ok, thanks!
