This work presents an electronic pipe instrument with audio feedback loops consisting of speakers, microphones, low-pass filters, and amplifiers.

Resonant sounds are generated by the loops without air blowing, and they seems to be similar to the acoustic resonance of a closed tube.

In order to play the instrument, control parameters such as gain factor and cutoff frequency that change the resonances are mapped with MIDI signals using a binary and expressive mapping.
