I got it primarily to use with a growing collection of small synth devices that all have different ways of syncing (CV/Trigger/Midi) and the OP-Z along with the OPLab module expansion (ZM-1) allows for that, except that it only switches between Midi/Trig/CV on one output. The other 2 outputs remain CV and the only annoying thing about it is that you have to remove the back plate in order to switch between those 3 output types (but the plate comes off easy).
The OP-Z works as a standalone device, or you can use it with either Mac/Android/iOS apps to have a visual display (pictured with iPad version).
It does more like sequencing lighting and some type of Unity 3D animation control (that I'm only referencing, possibly incorrectly because I haven't read up on it since I don't plan to use those features).
Its a beastly device that's travel-size, which is great for NYC apartment living.
This makes the boutique synths look large. Which is just strange.
