N2 - This paper presents a new electronic pipe organ based on positive audio feedback. Unlike typical resonance of a tube of air, we use audio feedback introduced by an amplifier, a lowpass filter, as well as a loudspeaker and a microphone in a closed pipe to generate resonant sounds without any physical air blows. Timbre of this sound can be manipulated by controlling the parameters of the filter and the amplifier. We introduce the design concept of this audio feedback-based wind instrument, and present a prototype that can be played by a MIDI keyboard.
