Abstract: Tones of percussion instruments produce different timbres, i.e. different tone waveshapes, depending on the strength of percussion. An automatic rhythm apparatus includes a rhythm tone generating unit which stores the tone waveshape produced from a hard percussion and also that from a soft percussion performed on a same percussion instrument. A rhythm pattern is constructed by rhythmically aligned tone command signals, for various percussion instruments, designating timings and volumes of tones to be produced. At each tone production, these two kinds of waveshapes are read out by mixing them appropriately. That is, when a loud tone is to be reproduced, its waveshape is read out from the waveshape memory for loud tones, while a soft tone is read out likewise from the waveshape memory for soft tones, and a tone of an intermediate volume therebetween is reproduced by reading out the loud tone and the soft tone at a mixing ratio complying to the desired degree of volume.

Abstract: Waveshapes of plural periods for plural channels having characteristics different from each other are stored in a waveshape memory and read out from it when a musical tone is to be produced. Read out waveshapes are respectively weighted by weighting data supplied from a weighting data generator and thereafter a desired tone waveshape is obtained by electrically or acoustically combining these weighted waveshape. As an example, the waveshapes are composed of plural attack waveshapes equal in number to channels and only one sustain waveshape. In this case, the attack portion of the musical tone is formed by the combined one of the attack waveshapes and the sustain portion is formed by the sustain waveshape. This enables the memory capacity of the waveshape memory to be reduced and facilitates the complex tone color control in the attack portion. In another case, each of the waveshapes is composed of an attack portion and a sustain portion, sustain waveshapes forming the sustain portions being matched in phase.

The reservation is made such that those channels which are idle are selected at the highest priority, those channels to which the earliest released keys are assigned at the second highest priority, and those channels to which the earliest depressed keys are assigned at the third highest priority.

This multiple key-depression is detected by a detection circuit. Tone volume of the rhythmic tone generated by the tone source is controlled in accordance with the detection of the multiple key-depression.

Abstract: The accompaniment apparatus for an electronic musical instrument comprises an accompaniment segment memory storing data representing a plurality of accompaniment segments which form a plurality of mutually different accompaniment patterns of predetermined lengths, and an alignment sequence memory storing, separately from the above, the orders with which these accompaniment segments are to be aligned sequentially.

This operation materializes the automatic accompaniment of any substantial length such as one whole piece of music, and allows the segment memory to have a capacity much smaller as compared to the case in which accompaniment patterns for the whole length of music have to be stored without skipping these segments of the same pattern.
