This is opposed to "monophonic," where only one note at a time can be played.</li><li><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.</li><li><strong>Square-wave:</strong>​ When its output is viewed on an oscilloscope, its wave resembles a square. It’s a “hard” sounding wave type, commonly associated with chiptune music and old video games</li></ul><p>These are the 3D models for the <a href="https://www.oskitone.com/product/poly555-synth-diy-kit">POLY555 Synth DIY Kit</a> from Oskitone.</p><h4>Assembly Guide</h4><p>Find a detailed assembly guide with printing and soldering instructions at<br><a href="https://oskitone.github.io/poly555/">https://oskitone.github.io/poly555/</a></p><h4>Updates</h4><p>January 23, 2021: Added reduced_test_case<br>November 2, 2021: Chamfer headlocking cavity on trimpot_knob<br>&nbsp;</p>
