Apparatus and a method for changing a resolution value of input musical data

An apparatus for changing the resolution value of input musical data in an electronic musical instrument, comprising:

• converting means for converting input musical data into conversion input musical data, wherein a rate of a change of the conversion input musical data when the input musical data is at least one predetermined value is different from that of the rate of change of the conversion input musical data when the input musical data is not the predetermined value, and changing a resolution value of the input musical data to the predetermined value;
• old input musical data storing means for storing old conversion input musical data previously output thereto from said converting means;
• comparing means for comparing the old conversion input musical data output from said old input musical data storing means with new conversion input musical data newly output from said converting means;
• and
• input musical data processing means for effecting a predetermined musical process according to the change of the input musical data input to said converting means or the new conversion input musical data output from said converting means, on the basis of the comparison by said comparing means.

A method for changing a resolution value of input musical data in an electronic musical instrument, comprising the steps of:

• (a) storing old input musical data previously input thereto;
• (b) calculating a quantity of a change of input musical data, newly input thereto and old input musical data stored in said step (a);
• (c) generating a plurality of change border data each having a different value and representing the resolution value of the input musical data;
• (d) determining the quantity of a change of the input data calculated in said step (b) is not less than a value of one of the change border data generated in said step (c);
• (e) effecting predetermined musical processing according to the change of input musical data, on the basis of the determination effected in said step of (d);
• (f) determining whether the value indicated by input musical data is equal to at least one predetermined value;
• and
• (g) changing the value of the change border data to that of another one of the change border data generated in said step (c), on the basis of the determination effected in said step (f), and changing the resolution value of the input musical data at the predetermined value.
