A sound pickup device includes: a housing; a mount portion via which the housing on an object constituting a portion of a musical instrument; a sound pickup including a plurality of the microphones respectively oriented in different directions; a first output configured to output a sound signal indicating a sound input to the sound pickup; and an installer configured to install the sound pickup on the housing such that each of the plurality of microphones is oriented away from the object when the housing is mounted on the object via the mount portion.

Sound pickup device and sound processing device

A sound pickup device includes: a housing; a mount portion via which the housing is mounted on an object; a sound pickup including a microphone; a first output configured to output a sound signal indicating a sound input to the sound pickup; an installer configured to install the sound pickup on the housing; a sensor configured to detect a vibration transmitted to the housing; and a second output configured to output a vibration signal indicating the vibration detected by the sensor.

A CPUsequentially changes over plural music pieces and reproduces the same by a program processing. Upon the changeover of the music piece, the volume of the tone signal that is being generated at each tone generating channel in a tone generating circuitis gradually decreased, whereby the tone signal is finally faded out. The volume decreasing speed in this case is such that the higher the priority order of the performance data is, the slower the speed is. The generation of a tone signal based upon performance data of next music piece data is assigned one after another from a tone generating channel wherein a fade-out has been completed. The volume of the assigned tone signal is controlled so as to gradually increased, whereby the tone signal is faded in. In this case, the assignment of the generation of the tone signal based upon the performance data of the next music piece is made earlier, as the order of priority of the performance data is higher. A first music piece and second music piece can be naturally changed over and reproduced as cross-faded without preparing plural tone generating circuit systems.

Automatic performance apparatus for reproducing music piece

This electronic musical instrument, having several sound sources, can generate one tone several times according to tone generation one operation, and generate chord. It can control the tone generation level and tone generation timing based on the instruction input and tempo clock.
