and a haskell functionally reactive game engine:
This app allows one to create - quite reliably - a modular synth system of your dreams, with many emulations of existing hardware modules being produced by the designers of those modules, themselves!
And .. there are more modules released every day. So many modules its hard to keep track of, actually.
So, if you're a synth nerd, get a look at VCV Rack .. seriously with this and Helm, not really much point in running other soft synths, at this point! :)
If so, you might want to reconsider the name of your tool/framework/whatever, because the name Helm is basically taken in many engineers' head.
If any of them should change, it's the ones that came after. But they aren't even remotely the same kind of software, so I don't see that it matters much. There isn't much room for confusion.
