Abstract: Provided is a transmitter for musical instrument and a mode switching method thereof. A transmitter for musical instrument which is mounted on an electric guitar determines the electric guitar is in a not-in-use state when a continuation time in which a square sum of accelerations output from a three-axis acceleration sensor is smaller than a power-saving threshold value is longer than a power-saving transition time, and the transmitter transitions from a normal mode to an energy-saving mode. On the other hand, when the accelerations in the energy-saving mode becomes equal to or greater than a release threshold value from a state of being smaller than the release threshold value or becomes equal to or smaller than the release threshold value from a state of being greater than the release threshold value, the electric guitar is returned from the energy-saving mode to the normal mode.

Abstract: Playback of a graphical representation of a digital musical score is synchronized with an expressive audio rendering of the score that contains tempo and dynamics beyond those specified in the score. The method involves determining a set of offsets for occurrences of score events in the audio rendering by comparing and temporally aligning audio waveforms of successive subclips of the audio rendering with corresponding audio waveforms of successive subclips of an audio rendering synthesized directly from the score.
