The design is beautiful, but it's not really clear from this page what it is.
It also appears to have some recording facility, but not clear how to get audio into it - can't tell what ports it has. Is the recording feature just for sequencing internal sample and synth sounds?
Or... they highlight the new version now has a 2.4ghz antenna - do you stream audio in/out over bluetooth?
A little explanation of basically what it can do or how they imagine it being used would go a long way
Maybe they do need a FAQ with a basic Q&A format, though. e.g.
Why does it have antennas?
How do I record?
What do the knobs do?
How many instruments are included?
How do I transfer recordings to my computer or phone?
etc.
In terms of wired connectors, it has USB-C, line in and out sockets, and a 4-pole audio jack for headset or mic support. OP-1 also has its own mic built into the body as well.
