Abstract: A performance training apparatus reads out a plurality of items of melody data each including a part, outputs all the plurality of items of melody data excluding an item of melody data including a particular part with a delay of a predetermined time compared to the item of melody data including a particular part. A light emitting element provided for each of operation elements of a keyboard is turned on to progress of performance of the item of melody data including a particular melody part for guiding operation of a corresponding operation element. All the delayed items of melody data each including a different melody part excluding an item of melody data including a particular melody part are fed along with performance data produced by the performer's performance to an external sound source to produce a musical sound.

Abstract: Prestored melody data is read out as the performance of the melody progresses. When event data contained in the read melody data represents a key to be depressed for a melody performance, the key represented by the event data is indicated to a performer. When the performer does not depress the key even when a timing when the key is to be depressed has passed, reading the melody data is stopped until the key is depressed. When the performer depresses the key before the timing when the key is to be depressed, relevant event contained in the melody data to be read out in a time period between the time when the key was actuated and the time when the timing at which the key is to be depressed comes is rapidly read out. When the event data rapidly read out contains volume control event data, the processing of the event data is changed such that the volume of the musical sound to be produced is minimized.

Abstract: When a plurality of effects are simultaneously applied to an input audio signal, a plurality of effect-algorithms each for applying solely an effect to the input signal are stored in a memory, and a plurality of combination-algorithms or combination-data which represent combinations of the effects and orders in which effects are applied to the input audio signal are stored in the memory. When one of the combination-algorithms or the combination-data is selected, effect-algorithms included in the selected combination-algorithm or combination-data are selectively read out from the memory. A program for applying effects in a predetermined combination and order is written by CPU based on the read out effect-algorithms and combination-algorithm or combination-data. Receiving the program, DSP successively applies effects to the input audio signal in accordance with the program.

Abstract: Root and type of a chord are discriminated at discriminators in accordance with the operation status on a fingerboard. The chord is designated according to a simplified fingering rule predetermined on the fingerboard so as to designate the chord.

Abstract: An electronic musical instrument having a function of selecting a musical tone parameter just before, or after during a musical performance is provided. The instrument has a first manually operable element such as a tremolo arm deflectably mounted on the main body of the instrument and positioned adjacent to stretched strings, and a second manually operable element (e.g., push button) attached to the first operational element. In one embodiment, the first element serves as a controller for varying a first musical parameter (e.g., pitch modulation) while the second element functions as another controller for varying a second, different musical parameter (e.g., tone color). In another embodiment, the second element serves as a variable function assignor for the first element. Depending on the function assigning of the first element, the second element provides a variable parameter controller (e.g., tremolo, vibrato).

Abstract: Root and type of a chord are discriminated at discriminators in accordance with the operation status on a fingerboard. The chord is designated according to a simplified fingering rule predetermined on the fingerboard so as to designate the chord. An automatic accompaniment or a manual play is performed according to the discriminated chord obtained at chord discriminating device.
