@ustk I think the confusion comes from the fact that at some point he was using Hise. I remember seeing Hise preset browser very clearly in an older plugin of his. But I don't have it anymore.
In any case, if you know of Hise plugin dev let me know about them! I want to give them a shot.
@Christoph-Hart I could be wrong then. I assumed that it was made with Hise Sampler because the preset browser is very similar to the one in Hise, he was using it. Here's how it looks:
It would be interesting to have a list of all the plugins made with Hise Sampler. We could make this thread something like this. A clean list with just the developer's company name and a link to its website would be nice.
As Hise Sampler experts, you have probably spotted plugins made with Hise. I'd like to know about them!
I'll start with a developer I think uses Hise: BeatSkillz.
I recognized the preset menu. 
I've played with Tensorflow to generate audio with AI and I was wondering if there would be a way to integrate a model into a Hise-made plugin?
I know it's possible to do it with JUCE (NeuralNote is made this way).
There's surely a way to do it in Hise. 
Hello,
I'm relatively new to using Hise Sampler, and most of my experience in plugin development has been with SynthEdit, Flowstone, and Maize Sampler. Before fully committing to Hise, I have a few questions:
Can I create a UI that is compliant with 4K displays and can be scaled? This has been a challenge with the development software I've used previously, as I couldn't create 4K-compatible UIs for my plugins. If this is possible with Hise, does it consume a significant amount of CPU resources?
Can I develop plugins with Hise that are compatible with Apple Silicon? Native compatibility is essential for me.
Is there a way to embed the sound content directly within a plugin? I'd like to create a synthesizer with my own wavetable, but I prefer not to require my customers to locate a separate content folder on their computers, especially when the sound content is relatively small (20 MB or less).
When it comes to romplers, how does code signing work on macOS? Is it a straightforward or complex process? Do I need to code sign the sound content files as well?
I hope these questions clarify my concerns.
