ABSTRACT:
TECHNICAL FIELD
The present invention relates to musical sound editing apparatus and recording mediums, on which a musical sound editing program is recorded.
BACKGROUND ART
There are musical sound editing apparatuses, for example, of conventional electronic keyboard instruments, having a general performance function as well as a pattern sequencer function. According to the latter function, accompaniment data, for example, forming a rhythm can be edited. In the general performance mode, a melody channel generates a melody part in accordance with keyboard performance and a plurality of accompaniment channels also generates musical sounds of accompaniment parts such as a rhythm, a base and a chord. In a pattern create mode which creates accompaniment data, one accompaniment part is specified and its accompaniment data is created.
When, for example, the mode is changed from the general performance mode to the pattern create mode in the creation of a pattern of accompaniment data in a guitar tone, the guitar tone is set. Then, the keyboard is performed to create an accompaniment pattern of a guitar tone, which is then stored in a memory. The mode is then changed to the general performance mode and a performance is given on the keyboard to generate a melody part, for example, of a piano tone and the created accompaniment part of a guitar tone is audibly generated by automatic performance.
A desired accompaniment pattern can rarely be created in a single operation. Generally, the pattern creation is repeated several times to obtain a finished desired accompaniment pattern. However, in the conventional musical sound editing apparatus, tone setting in the general performance mode is unrelated to that in the pattern create mode as a pattern sequencer. Thus, creation of a pattern of accompaniment data is very complicated.
For example, when a pattern of accompaniment data of a guitar tone is created in the pattern create mode, (1) a tone select switch is turned on to set a guitar tone to create the pattern, (2) the mode is then changed from the pattern create mode to the general performance mode to perform in the created pattern, and (3) when the mode is again changed from the general performance mode to the pattern create mode, the tone select switch is again required to be turned on to set the guitar tone. In this case, even if the tone of the keyboard in the general performance mode is the guitar one, the guitar tone is required to be newly set when the mode is changed from the general performance mode to the pattern create mode. That is, each time the mode is changed from the general performance mode to the pattern create mode in the creation of the accompaniment pattern, the tone select switch is required to be turned on to set the tone for pattern creation, which is very troublesome.
DISCLOSURE OF THE INVENTION
It is therefore an object of the present invention to provide a musical sound editing apparatus and a recording medium which facilitate creation of a pattern of accompaniment data in conjunction with tone setting in the general performance mode and the pattern create mode.
In order to achieve the above object of the present invention, according to the present invention, there is provided an musical sound editing apparatus comprising: mode selecting means for selecting one of a general performance mode for performing a melody generally and a pattern create mode for creating a pattern of accompaniment; specifying means for specifying a channel for creating the pattern of accompaniment from among a plurality of channels in which a corresponding plurality of tone data are specified; and musical sound controlling means, responsive to the mode selecting means selecting the pattern create mode, for controlling generation of a musical sound based on specified tone data in the channel specified by the channel specifying means.
According to another aspect of the present invention, there is provided a recording medium which prestores a computer-readable musical sound editing program comprising the steps of selecting one of a general performance mode for performing a melody generally and a pattern create mode for creating a pattern of accompaniment, specifying a channel for creating the pattern of accompaniment from among a plurality of channels in which a corresponding plurality of tone data are specified; and in response to said selecting step, controlling generation of a musical sound based on specified tone data in the channel specified in the channel specifying step.
Thus, according to the above arrangement, when the mode is changed from the general performance mode to the pattern create mode, the tone is changed automatically from that in the general performance mode to that of a channel specified by the channel specifying means. Thus, creation of a pattern of accompaniment data is facilitated in conjunction with tone setting in the general performance mode and the accompaniment pattern create mode.
