Yes, totally agree... and of course you (I) wonder what else there might be (as the OP-Z isn't reviewed super-well, is maybe a bit restricted, and doesn't have the awesome LED buttons of some of its competition) and you get into researching the Deluge, the Syntakt (with a stop-off via the Digitakt if sampling is more your thing), the Circuit Tracks, the Polyend Play, the MC-101, the Seqtrak...
Then there's the OP-XY which is even more powerful but unfortunately costs like 4-5x as much so I've not tried it.
