I owned one once and sold it like an idiot, but I am not getting one at this price, it really is too much. My DAW-less setup these days is made of a Digitakt, an Organelle and a Zoom H1n for recording.
checked ebay.de yesterday: someone offerred 3 new “back to school” edition OP-1 for 700 inkl. all accessories and bags but only with bank transfer and no pickup possible. 2 have already been sold. but they will not see their money nor the op1.
