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.

  I implemented this last night, and it solves the problem I was having with portamento: https://z.musictools.live/#95 https://z.musictools.live/#95

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 :)

  > 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). > A larger mixer component would be very useful, like 6 in to 1 out. 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. > Really cool to have a "reactor" in the browser, keep it up :) Thank you :)

  Update: edge disconnection is now implemented. Click on the the input-side port associated to the connection. This will leave you with a dangling connection which you can reconnect elsewhere, or click anywhere to drop.

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 ...
