碩士 === 國立交通大學 === 工學院聲音與音樂創意科技碩士學位學程 === 101 === In the research, Arduino and the Direct Digital Synthesis（DDS）are used to create the elastic interface synthesizer. Elastic rubber, the main control interface, are employed for the framework of VCO （Voltage Controlled Oscillator）system to control the frequency and modulation index via the characteristics of being stretched of the rubber. The synthesizer can produce six kinds of waveform（square wave, sawtooth wave, triangle wave, reversed sawtooth wave, sine wave and noise）in real time, it also provides various functions via patching. You can synthesize the timbre by Frequency Modulation, Delay Function and Logic Function. The voltage and MIDI messages can be used to link with other commercially available analog synthesizers and digital musical instruments. The goal of the research is to produce a low cost synthesizer, to develop an instinct-controlled, unique new interface instrument. The thesis contents: Chapter 1: Research motivation and the purpose. Chapter 2: The literature of electronic musical instruments. Chapter 3: System architecture. Chapter 4: Methods of implementation. Chapter 5: Summary and future work.
