so this randomly (!?) popped up on my youtube feed, downloaded demo and Im really enjoying it, so bought it 
(yes, its MPE compatible)
basically, its name pretty much explains what it is, but perhaps a couple of screenshots help too.
basically, you have springs, anchors and bodies, which you can excite, with various exciters - you can then pick up the sound via microphones. each of these has various properties e.g. spring has stiffness, bodies have mass.
all you just ‘drag to connect’, very simple.
you really don’t have to know what you are doing to create sound, its very playful.
whats nice, is beyond this, it has things like FX, and modulators (lfo, env, midi) even sound input can be a feed (hence the FX processor)
also the number of objects can be really large, some great presets showing this.
overall, you some really nice, (perhaps) leaning into the experimental side… and its visually really pleasing to watch it all work.
also, I was pleasantly surprised by its performance, have to say, I expected large models with the graphics to really ‘tank’, but so far with presets I tried it was all pretty good (Im sure you can kill it if you try ;))
Its seems to have been around for about a year, and is beta, with pretty active development… seemed stable to me
(I found one small bug, which Ive reported)
Its currently $70 (plus taxes), rather than $140, beta discount ($70).
tbc, I’ve no affiliation, just randomly came across this… and loved what I saw.
look forward to playing with it some more, I’ve got some ideas about using the Erae 2 surface to play with moving things around, and acivating different exciters based on position etc.
