Strange behaviour when loading plugin in host

[ulrik]

This message is what I get when I launch one of my plugins in Logic Pro X:

if I then just close the plugin window (not removing the plug) and then open the plug window the message is gone and it works as it should.

The behaviour happens every time I launch this particular plugin and it's a bit frustrating...
Anybody got a clue on what's happening here...?

@ulrik I should say that Hise is compiled from the "scriptnode" source code 2019-08-02

Further explorations:
Opening the plug in Reaper I'll get the same error message (both for au and for vst3 version)
Same with DSP-Quatro (au version)
Opening in Steinbergs Vst3PluginTestHost and in Dorico 2 is working with no error messages (vst3 version)

@ulrik Anyone having a clue what's going on?

Are you using MIDI files in your project?

It seems like you've passed an empty string into the loadFile() method, but it's weird that this doesn't fail consistently.

[ulrik]

@Christoph-Hart Yes I am, but no midi file named .mid only (as it says in the message)

[ulrik]

@Christoph-Hart Could it be this code that make this happen:

const var DemoSongsArr = ["Bel viso", "Lorda mornar", "Sakkijarven polkka", "Vals i natta", "Miss Karting",
"Marias vinter", "Pigornas tango", "Nocturne", "Kass theme", "Libertango", "Hej va de gar"];

MIDIPlay.setFile("{PROJECT_FOLDER}"+DemoSongsArr[value]+".mid", true, true);

@ulrik Comment it out and see if it works

Or use Console.print(DemoSongsArr[value]+".mid");

To see if it's the expected file name.

[ulrik]

@d-healey Haha, beautiful David, I used the "Console.print(DemoSongsArr[value]+".mid");" and at initialising I have nothing chosen in the combobox so it looks for ".mid"
So I guess I have to set a default value for the combobox when init, right?

So I guess I have to set a default value for the combobox when init, right?

Or check if the value is 0, which means no selection.

[ulrik]

@Christoph-Hart @d-healey Thank you both, now it's solved, I saved the project with a value assigned to the combobox!

[d.healey]

Console.print() - the most important function.

[ulrik]

@d-healey true, true, true.....
I just have to remember that
