摘要:
A desired rhythm instrument tone color can be assigned to a pad type performance operator. A desired type of repeated-tone mode, e.g., roll, flam or echo, can be selected by a switch operation or other suitable means. Upon operation of the performance operator, repeated tones having a rhythm instrument tone color assigned to the performance operator are generated with a stroke pattern having a characteristic peculiar to the tone color.

An electronic musical instrument with an automatic performance function includes manual performance device, an automatic performance device and a control. The manual performance device, having a plurality of performance manipulators to be performed by a player, generates a manual performance musical tone having a tone color in response to the player's performing. The automatic performance device automatically generates automatic performance musical tones of a plurality of parts respectively corresponding to a plurality of tone colors. The control, in response to generation of the manual performance musical tone.

In response to detection of a note-on instruction, a CPU assigns a tone generating unit comprising two tone generating channels and sets tone color control data of the assigned tone generating unit into tone generator registers. The tone color control data includes a parameter common to the two channels. Once the CPU gives a tone generation start instruction to a tone generator, the tone generator accumulates a frequency number common to the two channels to thereby generate a progressive phase common to the two channels. Waveform readout section reads out left-channel and right-channel waveform data from a waveform memory on the basis of the phase and waveform selecting information of the left and right channels. Tone characteristics of the read-out left- and right-channel waveform data are controlled by a characteristic control section on the basis of a characteristic control parameter common to the two channels.

An electronic musical instrument including: a scraper operator having a predetermined operation length in a predetermined operation direction, for detecting at least one of access, contact, and push of an operating member, and generating a plurality of signals to be detected within the range of the operation length; a time interval generating unit for receiving the signals detected by the scraper operator and generating a time interval signal representing a time difference between consecutively detected signals; and a tone signal synthesizer for generating a tone signal in accordance with the detected signal and the time interval signal each time the scraper operator generates the signal to be detected. Signals indicating the position, speed, and acceleration are derived from a plurality of consecutive signals time sequentially detected, providing various control ways of musical tone signals.

An electronic musical instrument provides plural channels from which manual-performance sounds and/or automatic-performance sounds (e.g., automatic-accompaniment sounds) are generated. Herein, the manual-performance sound is designated by a performance manually made by a performer, while the automatic-performance sound is designated on the basis of automatic-performance information which is stored in a memory or the like in advance. Normally, a new musical tone is assigned to an unoccupied channel which is not occupied with a tone generation, so that the new musical tone will be generated from the unoccupied channel. However, under a full-channel condition where all of the channels are occupied with the tone generation, a new manual-performance sound is assigned to one of the channels whose envelope value is the smallest. If a new automatic-performance sound is designated under the full-channel condition, this new automatic-performance sound is assigned to one of the channels occupied with the tone generation of the automatic-performance sounds which receives a key-off command and of which envelope value is the smallest. If it fails to detect such channel, the new automatic-performance sound is assigned to one of the channels occupied with the tone generation of the manual-performance sounds which receives a key-off command but sustains to generate the manual-performance sound. Thus, each of the manual-performance sounds and automatic-performance sounds can be smoothly and automatically assigned to an appropriate one of the channels.

An electronic musical instrument including a keyboard, a CPU and a sound source. The keyboard designates a pitch of a musical tone. The CPU detects common pitch data of one of predetermined series of pitch data or interval between predetermined two pitches, when a plurality of pitches are designated by the keyboard. The predetermined series of pitch data are stored in a memory in units of pitches which can be designated by the keyboard. The sound source outputs a musical tone signal having a pitch designated by the keyboard and musical tone signals having pitches indicated by the common pitch data detected by the CPU or having pitches corresponding to the interval detected by the CPU.

摘要:
Virtual damper position data, simulatively representing a position of a damper member provided for suppressing vibration of a string in a physical tone generating mechanism of the acoustic piano, is generated on the basis of key-on data, key-off data, released key position data, damper pedal position data, sostenute pedal-on data and sostenute pedal-off data. Release characteristic of a tone signal to be generated is controlled on the basis of the virtual damper position data. When the sostenute pedal-on data or key-on data has been supplied, the virtual damper position data is set at a value corresponding to a maximum damper release position. Virtual damper position data is variably generated on the basis of at least one of the released key position data, damper pedal position data supplied after the supply of the sostenute pedal-off data or key-off data.
