you could easily build that in Norns - supercollider doing the DSP and lua doing the sequencing
In fact if you want Earthsea kind of front end the trick would be to make the supercollider engine and fork earthsea plugging in the new engine
(& sorry - not volunteering - I’m way over extended right now
)
EDIT: just watched some videos about 296e and had a play with Norns earthsea - so yes definitely you could make something very interesting. Norns earthsea is pretty basic compared to the Ansible one - probably because there isn’t a good map between Norns parameters and CV out. so there would be a bit of work to do - however you could so something really cool with the grid, sequencing and a supercollider filterbank…
