Couldnt get sound to work on iOS but back at my Desktop now and wow these examples/presets sound really cool, great job! (The examples in the write up sound very weird btw...). Try out the 'app' here > https://kick-with-reverb.vercel.app/
I was looking into a way around this and I don't think it exists without building out an entire phone app.
Looks like this has been possible since iOS 17 but is not well documented.
