@iamlamprey Fixed with this PR: https://github.com/christophhart/HISE/pull/793

Changes repaint(), which I believe uses a cached path, to refreshAsync(), which forces a proper repaint.

@Taihongcraft start here https://audiodevschool.com/courses/hise-bootcamp/

@Christoph-Hart Thought this was fixed, but apparently not 🤷♂

can you confirm this is a vaiable solution?

Sounds like a hack, but then using HISE to create an installer app is already a bit weird.

Speaking of hacks, the "cleanest" hack would be to just deactivate the entire audio processing:

https://github.com/christophhart/HISE/blob/3ff4bbd9eb5596b084c7653e2d09fae2b4799c1e/hi_frontend/frontend/FrontEndProcessor.cpp#L96

This is the main callback for a compiled plugin (or standalone app). So if you add this code

#if IS_STANDALONE_APP return; #endif

at the beginning of this function, it will never call into the HISE rendering. Note that there are a few things that might be glitchy, some things in HISE rely on the audio thread to be working and initialised correctly.

Then recompile HISE

Great, thanks. I'll see if I can learn something... :-)

@Christoph-Hart awesome, thanks!

@Dan-Korneff No worries mate! 🤗

I figured it out.
In case someone else gets stuck at this point. When calling synchronously, the parameters of the function must be complete:

const var th = Engine.createTransportHandler(); th.setSyncMode(1); th.setEnableGrid(true, 5); inline function onGrid(grid, timestamp, first) // Parameters need to be complete { Console.print(grid); } th.setOnGridChange(true, onGrid);

@Christoph-Hart Perfect. Thank you very much!

It works now! You can now go back with Cmd+Z and you can also use the track's automation panel.

The only minor issue is that if I load a preset that has macro modulation, then close the plugin window and open the track's automation, it becomes laggy again. But if I open the plugin window again, it's fixed and the parameter disappears from the automation list. Kinda weird, but not so important.

@d-healey @Christoph-Hart And I just added two more 😆
The forum was just giving me a 503 error for an hour, I think it was acting against... ME AS A PERSECUTED PERSON!!!

Yeah alright, I divided the connections into 4 sub groups... I don't intend to modulate them though so all good 👍
