A few weeks in and I think the OPZ is almost brilliant, but hampered by a couple of things:
Not enough memory for user samples, I’d like to be able to remove the preset samples and replace them, but as of yet it isn’t possible. Roughly 24mb for user content feels a bit stingy, even 64mb would have been enough to fill all the slots with user samples, and still remain cheap and easy/fast to backup.
Buttons - a bit shallow and small, also the placement of the mixer button on the back should have not made it past the prototype stage IMHO, in use it isn’t very practical, it feels clumsy and ill conceived. Definitely should have been on the top surface, and latchable.
Size - it is smaller than you expect, and can be a bit fiddly, adding a midi controller certainly helps matters but at the sacrifice of portability, a shame I think. Especially considering that it could have been a little bigger whilst retaining portability - the OP-1 manages this fine, but the OP-Z could have even been a little smaller than the OP-1 and still remain portable but a bit less fiddly.
Unfortunately these points can’t (with the possible exception of the first) can’t be resolved with a firmware update, the early beta testers in my opinion should have picked up on these and communicated them to TE, whether they did or not I have no idea.
Still, as I said some things about it are brilliant, so I don’t regret the purchase at all, I don’t hold it in the same esteem as I do the OP-1 though, but I think that is a tough ask anyway. It definitely feels more like a Pocket Operator than OPerator though, so maybe it should have been called the PO-Z.
I think it is great that the (for me not too useful) DMX and Motion tracks can be used as regular midi tracks as well as all the other tracks, and it will be interesting to see what modules will be added, for me the Oplab module isn’t needed as I have a desktop Oplab, but a sampler/analog synthesis module might be difficult to resist.
The synthesis is pretty limited and basic compared to the OP-1, but I think these and the fx will be improved and added to in future updates, for the time being I’m mostly using samples and just a couple of the synth engines as I don’t like most of them. Personal taste, of course.
