OK, so I hadn’t spotted the reference in study2. In study 3, while it’s reasonably clear that we’re talking about a metronome, if we think about users learning Lua while also learning Norns, then we’ve just introduced a thing (an instance of a class I’m assuming) without mention of what it is that we’ve added.
The text says " this init function creates a metro called counter", and then dives into it’s members and methods (sorry, I’m learning Lua too, so apols if this isn’t the right terminology) without saying what this metro thing is.
For me, it jars, maybe for others less so??
