Though teletype isn’t trivial, I’d say that you’re seeing more of the developers perspective here rather than ‘typical users.’ For example, with Norns, a lot of the discussion is about what an be ported, and many of the people discussing are in fact very soft-engineering oriented. But most users may not be! Certainly don’t need to be.
Ansible for example is a simple module, just plug in a grid and go.
I’ve got a lot of the older modules as well and they are similar.
Not trivial but not really that much more of a challenge than, say, some of the Mutable Instruments stuff.
The barrier to entry is really the requirement that you have a grid. They aren’t cheap (nor should they be, they are very nicely made and lots of parts).
Teletype is coding, but not particularly hard for basic things. And it opens up a lot of cool possibilities.
What we’re really seeing now - with Norns, Teletype, ER-301, Organelle, Clouds and so on are devices that are meant to be repurposed (but don’t have to be). This level of interaction won’t appeal to everyone, for sure, but it is there for those who want it.
