Sunday Synth Jam: The Lemon Synthesizer is a performance/installation/musical work, created by Akemi Takeya, that uses a ‘citrus-based interface’.
From the official project notes:
Naturally occurring voltages in lemons are used as signal controllers for an audio synthesizer to manipulate audio processing.
The contents of a lemon are never stagnant and are constantly changing and self-renewing. With this bio-machine, Takeya sets a unique approach to art, science and invention.
Takeya lives and works in Vienna.
