The Arcade Machine is a PLL-based analog synth / harmonizer. It latches onto your input frequency and resynthesizes it as a square wave, which in and of itself produces a rich, video-gamey, gated fuzz. But that's only the beginning... one and two octaves down, one and two octaves up, plus an interval of your choosing are all at your disposal, essentially resulting in a 6-voice synthesizer that you can control with your instrument.
As far as we know, this is the ONLY analog harmonizer out there that can give all of the intervals in a 12-tone scale. With an expression pedal input that takes over the interval selection, also accepting control voltage (CV), the true potential of having all those notes can be unlocked. A sequencer can be used to run through a series of notes that will automatically follow your playing, which means you can program in anything from simple trills to arpeggios to full melodies.
Vibrato is also available, which acts on all of the voices. It has controls for Depth and Rate, spanning the range from subtle pitch variation to full-on glitched-out computer sounds.
Like all PLL-based effects, the Arcade Machine is monophonic, meaning it only works (well) with one note at a time on the input. As for the 'tracking' of that note, it was decided to make the controls as user-friendly as possible, with just a single knob, Gate, determining the sensitivity.
If you're ready to go into a world of fat bass, sawing mids, and laser beam trebles - welcome to the Machine.
