yeah, looks like pipes if focused on sample playback, rather than generic sound computer - which is cool if that’s what your after.
alternatives/options are good , and seems to have plenty of backers interested in it, so they are doing something that quite a few want.
Bela Salt is great, Ive ported orac (my modular pd patch thing) to it, and added OSC control to it - so it can be controlled via my iphone/ipad running lemur 
unfortunately, Salt was a limited run (30?) and they have not said they are going to build any more, so don’t think you’ll find one.
but I think Bela would do what your after, if your willing to roll up your sleeves 
it has lots of digital io (for buttons/leds) 8 analog in and out, audio in/out - no midi din, but can act as both usb midi device and host.
has a nice web interface () to program via can be programmed in C/C++, pd, supercollider , csound, or you could easily interface to other programming environments.
() similar to norns approach really.
you could add a small screen via spi, if your main interest is patch feedback. (seeing values, selecting samples etc) - alternatively, you could do as I did with Salt, and use OSC/Lemur, I quite like this ‘BYOS’ (bring your own screen) concept.
the forum (bela.io) is great for helping users achieve what they want, the guys at bela are really helpful, and extremely knowledgeable.
but its definitely not a ‘packaged’ solution…
I guess packaged, its norns/organelle or something like that, and do both cv and midi via usb.
