This paper introduces the design of a handheld musical input device that produces control data by measuring, and analyzing, the resonances of carefully tuned pipes. The device provides input control information to several virtual reed instruments running in parallel, responsible for producing the sound. Inspired by the khaen, a musical instrument f...

... are inserted into a windchest, called the tao, so they form two rows of anywhere from 6-10-but usually 8-pipes (see Figure 1). The perfect skyline arrangement of the pipes is purely aesthetic as the actual pipe lengths are determined using vent holes placed a distance L apart, approximately 3/4 L above and approximately 1/4 L below the position of the reed (see Figure 1). ...

The perfect skyline arrangement of the pipes is purely aesthetic as the actual pipe lengths are determined using vent holes placed a distance L apart, approximately 3/4 L above and approximately 1/4 L below the position of the reed (see Figure 1). The distance L is therefore, the effective acoustic length of the pipe when the finger hole is covered. ...

A nonlinear sound synthesis technique that uses a sinusoidal input signal and a rational shaping function is described. Complex spectrum evolutions are easily obtainable by varying different parameters. The global spectrum shape is essentially defined by only two parameters, those controlling the bandwidth and the formant position. Multiplication b...
In this paper we present a revised and improved version of a re-cently proposed extended source-filter model for sound synthesis, transformation and hybridization of harmonic instruments. This extension of the model focuses mainly on the application for im-pulsively excited instruments like the piano but also improves syn-thesis results for continu...

Figure 1: Design of the interface in which the measured sound signal is low-pass filtered, amplified, and played by a speaker unit to amplify the resonance in the pipe parallel pipes [4]. In her design, a hole was pierced at one end of the pipe and a microphone was placed in the middle to determine whether the hole was closed or not. ...
... Since no sensors are used, the interface is a simple, durable, and not attached to electronics. Additionally, the signal from the microphone can be easily used on a computer as discussed in [4]. Figure 1 shows the design concept of the interface. ...
... In addition, the mathematical principle of this work was not explained in full. Smyth [4] presented basic features, but we did not investigate phenomenon in depth once the resonant sound became more complex with two microphones. Further research is needed to determine the mathematics involved. ...
In this paper, we introduce a pipe interface that recognizes touch on tone holes by the resonances in the pipe instead of a touch sensor. This work was based on the acoustic princi-ples of woodwind instruments without complex sensors and electronic circuits to develop a simple and durable interface. The measured signals were analyzed to show that different fingerings generate various sounds. The audible resonance signal in the pipe interface can be used as a sonic event for musical expression by itself and also as an input parameter for mapping different sounds.
