The people complaining about the price tag: I get it. But the OP-1 is literally the only piece of music gear you can bring on an airplane and write a whole song. Why has no one else figured that out? With all these groove boxes etc, why has no other music gear taken the step of being portable and all-in-one. Show me another way to write a song in an airplane, and you can have my money.
Laptops exist too. And also who is writing whole songs on the OP-1? A song needs to be bounced, mastered and uploaded which is gonna require another device.
