This is like the original [OKAY](https://www.thingiverse.com/thing:2556995) but sports two octave of keys and an 1/4" audio out jack. - <strong>Monophonic:</strong> Only one note at a time can be played. This is opposed to “polyphonic,” where multiple simultaneous notes can be played. - <strong>Analog:</strong> There are no computers, microcontrollers, sound samplers, or anything digital involved. The sound you hear is the sound of a speaker being abused by discrete electronic components like capacitors and resistors and logic chips. - <strong>Square-wave:</strong> When its output is viewed on an oscilloscope, its wave resembles a square. It’s a “hard” sounding wave type, great for bass lines, and commonly associated with chiptune music and old video games.

Differences from [OKAY 1](https://www.thingiverse.com/thing:2556995): more keys, keys and key bed PCBs mounted to internal cradle piece, no key plungers, audio out jack ### Advice - The enclosure models are pretty big and are prone to warping. Minimize that risk by using a filament with low shrinkage like PLA and ensuring very good bed adhesion. ### Updates - **2018-02-13:** improved keyboard cantilever bond for Cura slicer (now `keys-2.stl`)
