Matrix modulation connection is broken in exported plugin

David Healey

@ustk Could all your problems be related to this juce 8 thing?

ustk

@David-Healey Perhaps... But I am JUCE 6... Or schizophrenic...

@ustk Why is xcode referencing 8.0.3

ustk

@David-Healey To this day I have no answer for this...

David Healey

@ustk Definitely only got one copy of the source?

ustk

@David-Healey yes, always had (custom branches but one folder/repo)
Also I just re-aligned develop origin onto upstream to be sure (I had some merge commits because of past manual fork syncing) but no changes regarding the issue and the VST3 crash.

@ustk Why is xcode referencing 8.0.3

After analysing everything, AI confirmed Hise is built and running on Juce 6, and it says:

The assertion you hit is most likely thrown by the JUCE-8 plugin's code (in the v8.0.3 message thread), not by HISE's JUCE 6.

Since I am debugging using pluginval which is built on Juce8, that's 99% the origin of XCode reporting Juce8 message thread

Christoph Hart

@ustk yup that's the plugin host telling his version number.

I tried to load your snippet, but the hardcoded FX is empty (of course, I don't have compiled your network) - is it just the script_fx network in the Script FX that I need to compile?

This looks remarkably equivalent to my snippet though (which worked).

ustk

@Christoph-Hart Yes it an embedded network, very simple, in the scriptFX

What about your snippet that I can test on my side?
And are you on windows or mac? I wonder if the difference can lie there... Especially since I have a straight crash with VST3 while AU, at least, can load

ustk

@Christoph-Hart Any news on this? Could it just be an OS issue? Unfortunately I can't test on windows before next month...

ustk

@Christoph-Hart Back on this as it is still not resolved...

The simple snippet from above:

mac:

AU doesn't work
VST3 doesn't even load

windows:

I can't do anything, just click on the hardcoded module gives a straight crash...

I re-downloaded a clean version of Hise to be sure.

At this point I am very confused, if I'm the only one reporting this, the issue might be on my end, ok... But how could it be the case if I have a fresh new Hise?

Even more strange, my main bigger project loads and the exported AU/VST3 are loading as well (just the matrix is not working)

At least the hacky solution I had here was working:

@ustk
I've had issues with the matrix modulator, and exporting and also some issues that appear in Hise, but I've not finished compiling my report yet. I believe there are a few issues, that I intended to make example projects for and send to Christoph. I know he's busy so I wanted to make it a useful report before I posted anything, but yeah I do know of some issues. I'm not sure if there ones you're experiencing are related to mine, but they might be

ustk

@griffinboy Thanks! at least I can see that I am not (entirely) crazy

I have solved (or Claude solved I should say) a few issues already but this one is persistent.
I will try again tonight with Opus 4.8 since is good for long task. It might make a difference here reducing the risk of hallucination...

If ever you can manage to get some time trying this snippet, and add it to your list if not already in, it would add even more usefulness to your report by keeping thing as centralised as possible.

It cost me all my Claude tokens but it's finally fixed!

@DanH Does any of your PR fix a broken modulation connection on preset recall?

When I save a preset with modulations in the matrix, when it loads, the lines are there in the matrix but the modulators are not effective anymore like if the connection was broken...

I can make new connections successfully, previous ones just don't work.

DanH

@ustk my presets seem to load ok with modulation connections still intact. I didn't know this could be an issue, my fix doesn't look at it specifically.

ustk

@DanH Hmmm... don't know what differs... I found a dirty fix:

ModMatrix.fromBase64(ModMatrix.toBase64());

to re-applies the matrix on itself in the postCallback so it remakes the connections. Dirty but working in DAW...

I also found out that:

Engine.addModuleStateToUserPreset("Global Modulator Container");

Was adding a redundancy in the presets so the MatrixData block was appearing twice:

  </MPEData>
  <MatrixData>
    <Connection TargetId="EQ Lo Boost" Mode="1" SourceIndex="0" Intensity="0.8445843446601942"
                AuxIndex="-1.0" AuxIntensity="0.0" Inverted="0"/>
    <Connection TargetId="EQ Lo Cut" Mode="1" SourceIndex="0" Intensity="1.0"
                AuxIndex="-1.0" AuxIntensity="0.0" Inverted="0"/>
  </MatrixData>
  <MatrixData>
    <Connection TargetId="EQ Lo Boost" Mode="1" SourceIndex="0" Intensity="0.8445843446601942"
                AuxIndex="-1.0" AuxIntensity="0.0" Inverted="0"/>
    <Connection TargetId="EQ Lo Cut" Mode="1" SourceIndex="0" Intensity="1.0"
                AuxIndex="-1.0" AuxIntensity="0.0" Inverted="0"/>
  </MatrixData>
</Preset>

but this doesn't seem to be the cause for the broken connection...
