@njAudio03 There also exists a convolution “reverb” module in HISE already. This probably doesnt address the your design/project objectives directly but studying it’s integration in the HISE source code (along with the FFT it relies on), along with @griffinboy External C++ primer should get you started.

@njAudio03 Check this box in project preferences

@njAudio03 said in Hadamard Mixing Matrix:

or will I have to do some C++?

if you can make a reverb in scriptnode let me see because I'm really curious. Maybe you could start from the delay template?

@njAudio03 Disable IPP in your project preferences.

@njAudio03 Yeah I did try ticking the box and it wasn't the issue. I have literally just figured it out tho! I had already had projuicer on my computer and that was upsetting Hise so i got rid of the duplicate version and it's working now. Thanks for your help.
