Very cool project! Do you have any plans for a Zupiter API? I'd love to build a utility module or two, maybe even a filter.

Thanks. Yes I do have plans for something like that. There's definitely a need for people to create new modules and reusable components, otherwise it gets too messy too fast.

It doesn't seem your oscillators are behaving correctly when you vary their frequency input. You seem to be doing something like phase = freq * time, which will break horribly when freq changes. Instead, you need to accumulate the phase over time based on whatever freq happens to be, like phase += freq * timeOfSingleSample.

So you think the oscillators should essentially be stateful? That might explain why I can't seem to implement 303-style slide correctly.

After fiddling a bit around, I would change the colors of modules that handle CV versus Audio or add even more colors to better comprehend a patch I've just loaded.

I was unable to figure out how to disconnect a cable. I tried alt, ctrl, shift click, right click, but none of it worked. I just wanted to add a second oscillator to the first example.

A larger mixer component would be very useful, like 6 in to 1 out.

Maybe add a highlight to the module I click on so I can use my keyboard to delete, move them around.

Do you plan to add MIDI out?

Really cool to have a "reactor" in the browser, keep it up :)

Really nice for quick things, otherwise there is also VCV Rack ( https://vcvrack.com/ ) that is a open source virtual rack with modular synthesizers. It doesn't have the graph UI that Zupiter seems to have, but a more of a skeuomorphic UI.

VCV rack is pretty awesome, and you can do a lot of things with it that you couldn't with Zupiter. It's much more of a professional tool and as far as I know it's very well-regarded in the modular synth community, and a good way to pick out modules before spending hundreds or even thousands on physical hardware.

However, I think Zupiter is a nice way to get people who've never played with sound synthesis interested, and the sharing feature is one thing that differentiates it from most browser-based music apps out there. You can easily show your friends what you've made, or modify what other people made.

> I was unable to figure out how to disconnect a cable. I tried alt, ctrl, shift click, right click, but none of it worked.

I will likely implement that later today. Clicking on an input-side port will allow you to reconnect it to something else (or to drop the connection).

Agreed.

> Do you plan to add MIDI out?

I've thought about it. Right now, it supports MIDI play/stop/clock output, so you can synchronize it with a drum machine using the ClockOut node.

Thank you :)
