@David-Healey just fixed it. It now seems to all work like intended. Again thank you so much for your help, I was panicking so much before. I'll now try to get it running in the project where the interface is already designed

@David-Healey OMG you're the goat. Seems to be all working now

Those where the samples im testing with currently.

@David-Healey what am I overlooking?

@David-Healey and one more issue sadly, I only got audio coming from the left channel only

@David-Healey I just got one more problem with my mute and solo script which is always throwing the error unknown function setControlCallback. This is the part of the code which it is referring to
// Initialize channel components
for (i = 0; i < NUM_CHANNELS; i++)
{
gainFX[i] = Synth.getEffect("SimpleGain" + i);

knbGain[i] = Content.getComponent("knbGain" + i);
knbGain[i].setControlCallback(onknbGainControl);

@David-Healey I added the preprocessor in Projucer, cleaned the build and tried building hise again, but now following error pops up

@David-Healey alright, but are there some specific lines of code I need to add, or is it just available in a drop down of some sort?

@LucaL I´ve tried changing it directly there but it wouldn´t let me change anything, so I can't override it.

@David-Healey can I just override it there to 32?

@David-Healey okay now when trying to import all 14 channels, I get following error Which preprocessor do I need to add, and where do I need to do that specifically?
