Awful confusing UX, take a look at VCV Rack for comparison
Consider being a little kinder. The developer probably will read this and it might ruin their day. Simply saying "I find the UX to be confusing" could have been less hurtful.
Kindness be fucked; the programmer clearly has the talent and motivation to not care and to have surely already discovered VCV Rack. What's bad about it though? VCV Rack's eurorack skeumorphism forces inefficient arrangement of modules because they're forced into a grid, forces separation of inputs and controllers like knobs unlike a synth like Audulus, which is totally unnecessary in a non-physical medium, ends up with a far less consistent modules because they're designed like eurorack modules of various brands. All these problems don't even compare to how VCV Rack spends a lot of extra resources on graphics because everything looks physical.
I actually think this is _much better_ than VCV Rack from a computer UX perspective. Makes a lot more sense to arrange things.
