no gimmicks. just signal in, sound out.
001 / first instrument
a bioelectric MIDI interface disguised as a plant pot. aluminum body. ceramic insert. stainless steel screws you can count. your plant generates the signal. you decide what it becomes.
signal to sound
in three steps.
two electrodes read your plant's bioelectric impedance. microvolt-level signals, captured in real time.
an onboard NE555 oscillator and ESP32-S3 convert raw biological data into MIDI notes, velocity, and modulation. thirteen scales. four presets. your rules.
route MIDI over USB or BLE 5.0 to any DAW, synth, or speaker. or use the built-in 8-voice synthesizer with reverb, delay, and chorus. no laptop required.
