Your link to organic analog texture, rhythm, noise and melodies.
Travels between chaotic and tonal passages as fast as your emotions shift.
It encourages fine playing gestures and rewards practicing.

Wing Pinger is an analog musical instrument, centered around a pair of 4-pole resonate low pass filters.
Surrounded by a network of comparators, pulse converters, binary counters and shift registers.
Despite the absence of oscillators, it's fully capable, and actually designed to generate sound on its own.

Filter Pinging

Wing Pinger exploits the idea of filter pinging (the operation of using narrow pulses as filter input). With Q near self-oscillation it makes naturally decaying tones of various lengths, assembling sounds from percussions to plucking. A special Q compensation is implemented, to balance pinging behaviors at different pitches.

Intuitive Playability

Essential controls unveil the complex synthesizer patch hidden within, respond musically to your playing. Control layout is in symmetric, follows natural hand position with comfortable spacing. All control components are of light action and silky smooth. As the signals from filters generate pulses and modulations, the Q controls become playful and interactive.


With multiple feedback and cross modulation paths, Wing Pinger operates according to the principles of chaos theory. All parameters except volume are interactive, future outputs are related to the current state as well as parameter settings.

Tonal Patterning

Be chaotic at will, you don't miss the expressions from melodies. Wing Pinger is capable of generating pentatonic patterns from its carefully weighted STEP modulation. With practice, you can play noise or melody at will.

External Sound Processing

Process stereo or dual mono signals through the filters, add spice to the tone, generate movements with special Wing Pinger modulations.

CV / Gate

Wing Pinger talks to modular synthesizers via Banana jacks. Use TRIGGER outputs to sync external synthesizers to filter pings. STEP outputs are weighted mixes from shift registers.

Rob Hordijk - who first brought out the idea of using shift register outputs for stepped modulation with his outstanding Rungler design. Peter Blasser - for his wild ideas for new, unique electronic instruments, as well as suppling me his PCB of various designs, of which most of my musical interface experiments were based on. Will Schorre - Double Knot is a great unique instrument, as well as a great platform for experimentation. Allieway - for her inspirational Double Knot cross clocking youtube video.
