And yeah a musician friend of mine we have a running joke where we'll say something is "a software engineer pedal." Meaning you see them in the home studios of people who make good money doing something else, while working musicians get by with the nearest Boss equivalent.
I've never used an OP-1, wouldn't know how to use one or evaluate it. But I've been on stage with enough of them to get the sense that, if used fully, they can for some approaches to some styles of music, fill the role of several other pieces of gear that would each cost more than what it costs.
So I think this one is both. It's a software engineer's toy, and it's also a workhorse tool for professionals. Honestly an impressive achievement, not a lot of things end up being both in any discipline.
