Abstract

A musical scoring system for scoring music arranged in measures. The system preferably includes a keyboard unit having a plurality of keys, a clock generator, a counter for counting clock signals generated by the clock generator and a summing circuit for maintaining a running sum of a series of quantized note, rest length values during each measure of the music to be scored. When keys are operated at the keyboard unit, a subtracting and converting means subtracts the value then stored in the register from the value stored in the counter and quantizes the result to produce a new quantized note/rest length value. This new quantized note/rest length value is thereafter summed by the summing means to the value stored in the register. Preferably, at the beginning of each measure of the music to be stored, the contents of the counter and the register are cleared and the summing means, and subtracting and converting means are provided by a central processing unit.

Claims

1. A music scoring system for scoring music arranged in measures, said system comprising:

(a) a clock generator;

(b) a counter for counting clock signals generated by the clock generator;

(c) means for clearing the contents of the counter;

(d) means for summing a series of quantized note/rest length values during each measure of the music to be scored; and

(e) means for subtracting the current sum generated by the summing means from the value stored in said counter and converting the result thereof to a new quantized note/rest length value.

2. The music scoring system according to claim 1 wherein said summing means, and said subtracting and converting means comprise a central processing unit.

3. The music scoring system according to claim 1 wherein said converting means converts said results using a predetermined look-up table to convert each result in certain ranges to predetermined singular values.

4. The music scoring system according to claim 1 further including a keyboard unit having a plurality of keys, rising and falling edge detector circuits coupled to said keys for detecting the actuation of the keys at the keyboard unit and means responsive to said rising and falling edge detector circuits for coupling the contents of said counter to said subtracting means.

5. The music scoring system according to claim 4 further including an interval encoder responsive to said keys to generate a code indicative of the particular key depressed and means responsive to said rising and falling edge detector circuits for providing said code as an output from said system together with said quantized note/rest length value.

6. The music scoring system according to claim 5 further including means for inhibiting the transmission of said code from said encoder to said output during rests.

7. The music scoring system according to claim 1 wherein said summing means includes a register for maintaining a running sum of the quantized note/rest length values and wherein said clearing means clears the contents of the counter and said register during each measure of the music to be scored.

8. The music scoring system according to claim 7, wherein each new quantized note/rest length value generated by the subtracting and converting means is subsequently added to the contents of said register by said summing means.
