Ah, well, or, instead of adding another hardcoded path for the waveform generator...
you could probably draw your own waveform in the already existing wavetable synth? :) (I just found it...)

Master Chain + -> Wavetable Synthesizer

Hi hisefilo,

as far as I can see, HISE has a Wavetable synth implementation. It comes with a set of pre-defined waveform primitives.

The code looks like this:

File not found · christophhart/HISE

The open source framework for sample based instruments - File not found · christophhart/HISE

GitHub (github.com)

So, to support your waveform, it would be either possible to add the "Tangent" waveform in the code and create a custom binary build -- or (my favourite) implement a Serum like wavetable editor UI for the IDE (and later for the runtime UI)...

I would eventually like to dive deeper into the code of HISE... so, maybe I will just pick your waveform and implement it. Would be a nice starter for me to get familiar with the code.

Best,
Aron
