Electronic apparatus having a tone generating function
First Claim
1. An electronic apparatus having a tone generating function, comprising:
- input means for inputting note data;
memory means for storing the note data input by operation of said input means;
a readout key which is provided independently from said input means and which is operable for reading out the note data from said memory means sequentially one by one every time the readout key is operated, after said note data is stored in said memory means by said input means;
first detecting means for detecting a key-on period during which said readout key is kept operated;
second detecting means for detecting a key-off period during which said readout key is not operated;
duration input means coupled to said first and second detecting means for inputting tone duration information into said memory means, said input tone duration information designating tone producing intervals and tone releasing intervals according to the key-on period and the key-off period, respectively, with respect to each input note data.

Abstract
When a key among ten keys or function keys in a keyboard section is operated with a mode selection switch in a key input section set in a recording position, the note data corresponding to the operated key, flag data and tone duration data corresponding to that note data are stored as one-key play note data in a note memory. When a one-key play key is operated in a timed relation to a given rhythm after clearing an address counter in the aforementioned state, musical sound is generated according to the note data stored in the note memory, and at the same time note data is stored again together with flag data for auto play and tone duration data in the note memory.

9. An electronic apparatus having a tone generating function, comprising:
-
mode setting means for setting the electronic apparatus to an arithmetic operation mode and to a music mode; input means including numeric keys and function keys for inputting note data in said music mode and for designating a number and four arithmetic operations in said arithmetic operation mode; memory means for storing the note data input by operation of said input means in said music mode; a readout key which is provided independently of said input means and which is operable for reading out the note data from said memory means sequentially one by one every time the readout key is operated in said music mode, after said note data is stored in said memory means by said input means; first detecting means for detecting a key-on period during which said readout key is kept operated in said music mode; second detecting means for detecting a key-off period during which said readout key is not operated in said music mode; duration input means coupled to said first and second detecting means for inputting tone duration information into said memory means, said input tone duration information designating tone producing intervals and tone releasing intervals according to the key-on period and the key-off period, respectively, with respect to each input note data, in said music mode; and operating means for performing arithmetic operations designated by the operation of said function keys in said arithmetic operation mode.
