Embodiments of the keyboard system that can determine accurate key operation. The system provides immediate processing of the data input streams from various strike sources, the key stroke depth data, the key strike speed data, the key strike acceleration data. The movement state volume V can be calculated using a formula shown below, based on the key strike depth D, the key speed S, the key acceleration A, the coefficient a, b, c, and constant d. V=a*D+b*S+c*A+d. When the volume level exceeds the predetermined level A, the system determines that the key has been pressed. When it is determined that the key has been pressed, the 'note-on' information is outputted to the sound source. The velocity value included in the 'note-on' information is calculated with reference to the velocity curve based on the key speed when it is determined that the key has been pressed.

Keyboard processing system and method

An electronic musical instrument comprising a CPU, a display device, operators, a data interface, and a storage device storing music tone data, all interconnected via a bus line, wherein upon an inquiry from a PC connected to the data interface for a device identity, the electronic music instrument transmits via the data interface the device identity of a removable media drive. In some embodiments, wherein upon commands sent from the PC, the electronic musical instrument transmits the stored music tone data in a format consistent with the removable media drive. An electronic music system comprising such an electronic musical instrument connected to a PC via a data interface. A method of data communication between an electronic music instrument and a PC.

Electronic musical instrument system and method emulating a removable media drive

An electronic musical instrument has a server section to enable instrument settings to be made by remote control from a terminal on a client side through a communications circuit such as the Internet, and thus makes it possible to easily carry out the setting and resetting of an electronic musical instrument for which specialized knowledge is required.
