Abstract: Chord to be performed is presented to a user. Chord is detected based on one or more notes performed by the user. When it is not detected that a chord has been duly established, one of the notes performed by the user is detected as a root note of a chord. Comparison is made between the chord presented to the user and the detected chord to make a determination as to whether at least the root note of the detected chord matches the root note of the presented chord. The user is informed of a result of the determination. Thus, not only when the user has accurately executed performance operation for all component notes of the presented chord but also when the user has executed performance operation for only the root note of the presented chord, a chord performance evaluation is made, determining that the user has accurately performed.

Abstract: Two-dimensional display section is provided near a keyboard, and, in accordance with performance data, this display section is caused to effect a dynamic display moving, in a given two-dimensional trajectory, from a first display position corresponding to a key to be currently depressed to a second display position corresponding to another key to be next depressed. Thus, a human player can readily intuitively predict the key to be next depressed and depression timing of the next key, in accordance with the display drawing a so-called bouncing-ball-like two-dimensional trajectory that appears as if a ball were bouncing. Further, with a performance guide by the non-conventional or novel bouncing-ball-like two-dimensional trajectory display, the human player can enjoy continuing to play the keyboard, without getting bored, as if the player were following a bouncing ball.

Abstract: A clock signal generator circuit has a clock generator for generating clock signals to be supplied to a central processing unit and to functional blocks, and clock selectors. The clock generator divides the frequency of a source clock signal, to form a clock signal having an optional period. Namely, the clock generator suppresses at least one active or inactive state of the source clock signal, to generate a clock signal whose period is an integer multiple of that of the source clock signal. The clock selectors receive the clock signals generated by the clock generator and selectively supply them to the CPU and functional blocks. The clock signal generator circuit is capable of operating a microcontroller system at a required minimum speed, to optimize the power consumption of the system.
