I recently picked up an OP-1 synthesizer from Teenage Engineering. The OP-1 is a marvel of design and engineering. But I already knew that, which is why I was so interested in it. What I didn't expect is that it has some of the best documentation I have ever seen.
Of course, saying it is the best documentation ever is a bit of an exaggeration. Kind of like saying Rembrandt is the best painter ever. Better than Renoir? Better than Tintoretto? When you get into the realm of art and genius, comparison becomes irrelevant. What is important is that they far outshine any of their contemporaries.
The same is true for the documentation of the OP-1. To start with it isn't "documentation" per se. There is no manual. There is no paper Getting Started guide. When you open the package (which serves as its own case, which is also pretty neat) there is a clear plastic overlay on top of the synthesizer, describing each of the controls. That's it.
Well, not quite it. Because in the available space over the keyboard the overlay also includes a 8-step "QuickStart" for getting started using the OP-1. Just enough to show off some of its key features and get you playing with it (literally and figuratively).
Does it cover all features? No. Does it go into detail about what each knob does? No. But it makes you comfortable trying them to find out for yourself. Besides, there actually is a more detailed printable user's guide available online. But you won't find that until you've at least looked over instructions on the overlay and tried it out a little. (There is a link to the online document in the lower-left of the overlay.)
Is it perfect? No, not quite. The plastic overlay can get a little wrinkled and not lay flat. Also, since much of the OP-1 is light gray, the white printing on the overlay can be a little hard to read when it is actually covering the device. But these are minor quibbles. For 95% of its purpose, the "documentation" for the OP-1 is as well designed and inspiring as the device itself. Nothing short of exceptional.
