Summary:A theremin is a musical instrument which is played as a non-contact haptic device. Two antennas are used in combination with the hands of the player to generate two oscillatory signals, one for the tone and one for the volume of the audio signal produced. The design and experimental results of a hybrid digital theremin system are presented in this report. The design consists of two components: a hardware section based upon a previously designed system to which modifications have been made. Schmitt Trigger digital gates are used for the generation of the control voltages for the oscillators which in turn generate two signals at different frequencies. These signals are fed to a data acquisition board and from this sent to the second and novel component of the system: virtual instrument software developed in LabVIEW and running on a computer for the control of parameters of the musical signals produced. Virtual instrumentation is also used to enhance the output, by adding harmonic components and performing equalization. A general description of the system and results of the prototype testing are reported here.
