Oddly, I’ve been playing with this library just this week. I’ve also been looking at various alternatives (some of which have already been mentioned in the comments here).

The only functionality I’m actually looking for is the ability to connect and disconnect elements using virtual cables (that flex and look good, just like those in rete). It’s for a software synth patchbay (like those used in the Reason digital audio workstation software). So, ultimately, even though this library is impressive, it isn’t quite the right fit for my project.

If anyone can recommend an alternative that focuses purely on cabling, I’d love to hear about it!

View on HN

I am developing a generic data flow programming tool, it is only view and the model or engine can be added on top of it.

If you want to use it I am more then happy to help: https://github.com/fibo/flow-view

Do you have a working online example? The links don't seem to work (404 or blank), and I'd like to see whether I should try it if I at some time get to write a dataflow graph config tool sitting on top of timely-dataflow. Especially because I expect to use it for a sizable event processing graph.

Thank you for the feedback, I restored the online example here: http://g14n.info/flow-view/examples/basic/

I am also working on an engine that is able to run javascript code: https://github.com/fibo/dflow

Currently I am working on a rewrite and I will use flow-view to create custom nodes, for example nodes that have a canvas or a graph inside (images a SinOsc node with a graphic preview). The engine is able to order nodes by level and run them usinng the graph order, it is not an event based engine but every graph compiles a JS function.

Not sure if it fits the bill exactly but did you look at VCV Rack?

I was going to recommend VCV Rack as well :-)

I've downloaded vcvrack, but not actually tried it out yet. It looks awesome. However, the project I'm working on is a web-based synth using the HTML5 Web Audio API. It's built using Tone.js and NexusUI.js, so vcvrack isn't really applicable, as far as I can tell at least!

Thanks for the recommendation though. :)

Sounds cool! Will the project be open-source by chance?

Relatedly, what are your thoughts on Tone.js?

https://tonejs.github.io/

Yes, it will be floss. I've still got a way to go to fully flesh it out, but I'm getting there. Here's a screenshot of what I have so far - https://i.imgur.com/bEBIBFF.png. The sequencer, effects rack to the right, keyboard, pad on the left, wave selection, oscilloscope, level meter, master volume and bottom two dial racks (dry/wet levels) are all working. The rest is yet to be plumbed in, but I've added it in to try and get some idea of the final layout.

At present, the sequence of connections for each effect are pre-determined, but I'm working with the idea that a button will flip the synth around so you can patch the units in any order you wish. Another idea is to start with an empty rack and have you add them in and move them around however you wish too, so you could have more than one of each type in the chain. Very much still a work-in-progress!

I'm actually using Tone.js for this project. So far I'm finding it very useful.

I've used jsPlmb (years ago) and it worked well.
