@David-Healey it adds an empty slot, but it basically loads the first file anyway, so the last file of the list won't load.

I added a blank wav file and use it to call the Room sampler, but it's not working :/ I'm doing your Hise scripting foundation course, but it's still hard to put it in an Audio context.

inline function onComboBox0Control(component, value) { local smpRoom = Synth.getChildSynth("smpRoom"); if (value > 0) convRev.setFile(irs[value - 1]) && smpRoom.setAttribute(Gain, -100) && convRev.setAttribute(WetGain, 0); else if (value = 4) convRev.setAttribute(WetGain, -100) && smpRoom.setAttribute(Gain, 0); }

the IRs get loaded, but volumes don't change and i get no error when compiling. what am I doing wrong? (4 is the blank wav file)

@JamesC You can adapt the example in the docs:

https://docs.hise.dev/hise-modules/effects/list/convolution.html#parameters

Instead of a combo box, use control callbacks on the 2 buttons to call setFile(). You'd put the list of impulse names in an array, then the buttons would load the previous or next impulse.

@Yinxi You can use either parameter\processor id or a control callback. If you want to do two things then it must all be in the callback.

Or you can use a broadcaster.

@ulrik

Ohh yess!! Thank you so much! You helped me a lot. I am good at c++ bad i have no idea about scriptnode.

Thanks!!

@VirtualVirgin whaaa 500mb?? Its take alot for a normal browser window to hit that much ram. What does ur plugin do?

The Scripting Course Bundle launch offer expires in 2 days.

@pgroslou Thanks David. I was able to find an example using LAF in the HISE documentation that works well and solves my problem. Much better than using Paint Routines. 👍

@udalilprofile I think this is what you are referring to: https://forum.hise.audio/topic/10913/correlation/5?_=1765392189920

@David-Healey An issue I run into now is when

function onNoteOn() { for (note in track) { if (note.isNoteOn()) { Console.print(note.dump()); Console.print("Note: " + note.getNoteNumber()); //Synth.playNote(note.getNoteNumber(), note.getVelocity()+1); //Synth.playNote(note.getNoteNumber()+12, note.getVelocity()+1); //Synth.playNote(note.getNoteNumber()-12, note.getVelocity()+1); } //Synth.noteOffByEventId(note.getEventId()); } } function getNoteOn(list, noteOn) { for(note in track) { if(note.isNoteOn() && note.getEventId() == noteOn.getEventId()) return note; } } MIDIPlayer1.flushMessageList(track);

I uncomment any of the synth.playNote function calls, it plays very distorted, notes playing for far longer than they are supposed to, like I mentioned earlier.

After all struggling I've decided to switch to pure C++ VST3 programming.

I had to break that down to just 1. Here's a screenshot of it now.

@ustk That makes total sense. I also read the thread that @resonant posted. I think Im understanding whats going on now.

Thank you guys. 🙏

@Chazrox said in Multiple Styles for Controls?:

@bwoogie and when you're done with that....🤣

...I'll know right where to find you 🙃

@David-Healey Thanks, David. I did take your courses earlier, they’re true life savers!
It also makes sense that the File.loadAsBase64String() function isn't available on the release version of HISE. I previously compiled HISE following your tutorial, but I ran into the issues I described in this forum post, where the string returned from File.loadAsBase64String() didn’t seem to be a valid base64 string. I’ll compile it again, and hopefully I won’t run into the same error. Thanks a lot!

@David-Healey Thank you so much! I'll check it out now!

@Oli-Ullmann A broadcaster might be another option - not sure.

Yay! I was able to get it working. I guess the bounds were off. Thanks for the direction.

Is there a video tutorial of how to compile SNEX? I am trying to follow along with this tutorial on the forums, but It is very wordy and difficult to follow...
