Abstract: In a control system of a digital mixer, first class devices are connected via a first class bus, and second class devices are connected to each first class device via a second class bus. The number of first class devices, which require a specific function for adding source and destination addresses to data, can be reduced by the number of the second class devices. Moreover, the second class device which does not require the specific function for adding source and destination addresses to data input/output operations is cheaper than the first class device, resulting in the implementation of simplified configuration and reduced production costs.

Abstract: There is provided an electronic keyboard musical instrument that gives the performance feeling closer to that given by an acoustic piano and enables techniques of expression closer to those used when playing the acoustic piano. Touch information is generated based on first information output when an ON event of a first (deep) SW of a switch section occurs, and a tone generator section generates a musical tone according to the touch. When an OFF event of a third (shallow) SW of the switch section occurs during key release, the musical tone being generated is progressively damped, and at the same time a musical tone having a predetermined characteristic is generated. The OFF event of the third SW is made equivalent to a damper-leaving position in a key stroke of an acoustic piano keyboard.

The bus system has a serial clock line for transmission of a clock signal, and a serial data line for transfer of a data signal from a source device to a destination device in synchronization with the clock signal. The source device operates as a master to commence a communicating session such as to send the clock signal to the serial clock line and to send the data signal to the serial data line in synchronization with the clock signal. The destination device operates as a slave so as to receive the data signal based on the clock signal. The source device formulates the data signal containing a unique address specifying the destination device such that the destination device can receive the data signal exclusively from the source device.
