Oh, nothing fancy, just an analog square wave synthesizer -- That's OKAY... 2!
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.
