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.

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 :)

It's probably on your backlog, but one thing would be useful is to build "components" with a container module. To group modules to a single entity, so they could be closed.

I'd assume it would have 3 inputs / outputs: gate / CV / audio and a custom label. Not sure how I/O is done in other node based editors, probably worth some investigation :)

Undo button would be nice, I keep making mistakes ...

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.
