For me OP1 is by far the better instrument, I don’t care about DMX lighting, photomatic or the unity stuff, I care about making music, so none of that is of interest to me.
The OPZ build quality is pretty poor, definitely not built to last, tiny buttons are a bit too fiddly, the recent update allowing the function buttons to latch was long overdue and should have been there from the start. Updates can break old projects too which is a bit annoying.
The sequencer on the OPZ is excellent, the sound engines are pretty good too, the mute groups, tape track, punch in fx, and step components are very nice.
Can also be used as a midi sequencer. Impressive in such a tiny package, but at the cost of usability.
TE was definitely not lying when they said the small size will annoy, it does but only because it is fiddly to use, the buttons are very low profile and very low quality.
I’m definitely more a sequencer guy than a tape guy too, BUT the tape on OP1 is much more than just tape, it can be thought of as an audio sequencer, but most people, especially the synthfluencers just use it in the very basic tape way. But you can do lots of really cool stuff with the tape outside of just recording 4 bar loop sections.
Like most TE gear both my OP1 and OPZ have had numerous faults, make no mistake I love their gear, I love their design aesthetic and most of the employees seem to be really cool and helpful. But, they really need to get their act together when it comes to quality.
I never treat my gear roughly, I’m not heavy handed and I don’t do dumb things like use rigid cable adapters, both my OP1s and OPZ are kept in cases when not being used.
If the OPZ was better built it would be great, as it is it feels like not many will still be working in 10 years.
