Tune In Tokyo is a source of unusual, LFO-animated frequency textures. TiT is an altered digital sinewave generator that demands attention as it sweeps the full audio spectrum with mega-aliasing and decimation artifacts, the subharmonics of three ultra high frequency master clocks engaged in a mathematical battle that you won’t dare ponder the details of.

1/4″ line output. Powered by 9V battery. Uses 10mA of current; estimated 48 hours of play time on a fresh alkaline 9V battery.

Tune in Tokyo began as an experiment with a cool yet seldom-seen idea from Don Lancaster’s CMOS Cookbook called “digital sine wave generator”. I modified the circuit with extra oscillators, altered the way it handles data, and gave it an LFO. Its controlled with 5 knobs and 2 switches for plenty of variety. Take a look at these spectrograms to see the complex mix of frequencies that cris-cross the entire audio spectrum as they converge and diverge under LFO control.
