yeah, thats the question isn’t it… 
Ive backed an experimenter kit too, as my other belas are now all in use…
(bela max + pepper -> eurorack, bela mini -> AE modular rack)
quite looking forward to adding these into a modular context (both AE and Eurorack), always nice to add more human contact there - though I might team them up with teensy or arduino for that as they use less power than bela mini.
I also like the idea of building a standalone instrument using them … which is probably what I’ll use the mini for.
good thing about KS is you can alter you pledge right up to end date, so I might add a few sensors/crafts to the pledge - once I decide on which projects Im going to do.
