Abstract: In an electronic tuning apparatus used in electronic stringed instruments such as an electronic guitar, an electronic violin, and so on, at least one string is extended along the fingerboard. Prior to picking performance, a present state of the extended string is examined through picking said string. Preferably, a reference pitch data extracted through the string-picking manipulation is stored. During a live picking performance, a performance-pitch data extracted is converted into a data for defining a properly-tuned sound-frequency in accordance with said extended string state. A musical-tone having a corresponding sound frequency is generated based on data for defining said sound frequency.

Abstract: Data representing a pitch is extracted from an input waveform signal and a musical tone having a corresponding tone pitch is generated. By chromatically designating a tone pitch, a musical tone having a tone pitch of a semitone unit is generated from a sound source circuit at the starting of the input waveform signal. After tone generation is started, in the system for updating a tone pitch having an interval of less than a semitone interval, a musical tone is generated in accordance with various performances. Therefore, a musical interval after tone generation is started can be clearly recognized, thus obtaining an excellent musical performance effect.

Abstract: All the combinations of upper-level parent parts and lower-level child parts constituting parent-to-child relationships in the structure of the parts are registered in a predetermined file in advance. When an arbitrary upper-level parent part is designated, all the child parts which are associated with the parent part are extracted by referring to the file. It is then determined whether a combination of parts including each extracted part as a parent part is present or not. If it is present, the referring operation is repeated again by setting each extracted child part as a parent part. When it is determined that a combination is not present, a corresponding child part is output.

Abstract: Combinations of operation data such as timbre data, effect data, and the like, which are designated for a musical performance, are stored in a memory. The operation data is read out from the memory, and a musical tone signal corresponding to the readout operation data is generated and a musical tone is produced. Operation data is an operation mode can be transferred to, e.g., a normal mode, and a musical tone signal corresponding to the readout operation data can be generated and a musical tone can be produced in the normal mode. Operation data set in the normal mode can also be transferred to the operation mode. Part of the combined operation data can be easily updated.

Abstract: When picking of a string is performed, the vibration of the string is detected accurately and quickly. When a fret operation position is changed during generation of a musical tone caused by the string picking, the pitch of the musical tone is changed to the one corresponding to the new fret operation position without generating a new musical tone. When the same string is stroked successively, the succeeding musical tone is generated while keeping the reverberation of the previous musical tone. The musical tone once generated will be stopped from being generated upon elapse of a predetermined time from the beginning of the tone generation, irrespective of the type of its timbre. When a fret operation state is changed to an open-string operation state after the string picking, the generation of the musical tone being generated stops at that timing.

Abstract: A pitch of a musical tone to be generated based on a breath sense signal detected by a breath sensor is set by a pitch setting operation of a pitch setting section. When the pitch setting operation is changed during generation of the musical tone based on the breath sense signal, pitch data corresponding to a pitch newly set by the change in the pitch setting operation is output upon elapse of a predetermined time from the timing of the change. The pitch of a musical tone being generated is altered to the pitch according to the new pitch data upon elapse of the predetermined time.
