The POLY555 is a polyphonic, analog, square wave synth based on the 555 timer chip.
- Polyphonic: Multiple notes can be played simultaneously. This is opposed to "monophonic," where only one note at a time can be played.
- Analog: 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.
- Square-wave: 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
These are the 3D models for the POLY555 Synth DIY Kit from Oskitone.
