I think to be useful it needs a mode of playing, that is always musical / in tune.
Not yet sure how to really do it, but one concept I like from NI plugins is that you have multiple keyboard zones: one zone is for notes, others are e.g. for patterns or styles. Imagine a guitar where one zone is for the chord type and tone, another for the striking pattern...
The challenge here is probably the resonance algo for multiple systems based on multiple notes... Maybe the piano concept would be handy here... imagine instead of having 3 strings like on the piano the instrument to be one system for each key... that excite each other via air or direct resonance points... the systems should be automatically tuned based on one reference system (e.g. using automatic string length or tension scaling)
Anyway, amazing work and having it on GPU allows this really to scale.
I think it depends a lot on how research AI generated traffic counts towards these stats.
Also, if there is no answer yet on the web the AI may also not know it. Then these questions should still end up on SO.
I might add, that SO also could build their own chat / research UI. It would need to have some benefit over others, but I guess the community aspect of it alone would suffice...
