It's possible, yes. It's also true that e.g. when you look at audio synthesizers, a shockingly large portion of the digital gear out there doesn't do it, making this a theoretical argument for a lot of the market, especially the cheaper end. Controllers or intermediate signals being sampled slowly or with too low resolution is a common complaint with digital or hybrid gear. There's also other, more general UX aspects that influence how an instrument feels to play that influence how it is used. So while I'm not fan of people insisting that they can get the perfect sound only with analog gear, I find the "but it's just math" arguments equally annoying.
