The OP-1 is a powerful synth and sampler. It’s also small and so well built that kids can safely play with it, mash the buttons, and have a blast. A favorite game among OP-1 parents is to sample kids singing, cut the sample into pieces, pitch shift it all over the keys, and have them create a cacophony of sound. The trouble is that the OP-1 is full of powerful menu and settings keys that are right next to the sound-producing keys. When you’re mashing the keys, it’s too easy to hit all the wrong ones and need help making the synth beep again, especially if you’re two.
This 3D-printed cover hides those menu and settings keys and leaves exposed the keyboard and sound-modifying keys. Mash and explore all the exposed keys, and they all either make sound or modify the sound.
The two-year-old operator shown had his longest solo session to date on the OP-1 with this cover. He has tried toy synths and kid instruments, but they don’t hold his interest. He is discerning enough to distinguish real hardware from fake, and only wants the real stuff. This cover makes that practical.
The small holes over each key allow access to the recording functions to an adult user with a paper clip or other small diameter too.
