When the display magnification is not “X1”, rough data is stored in the PCM waveform memory 7. Therefore, interpolation is performed. That is, a straight line interpolation is performed based on the values of two points that are adjacent to each other.
When the magnification of the X axis is “X2”, one point is at the middle, and when the magnification is “X4”, the point is at the middle.
In the case of three points in between and "X8", the amplitude values of seven points in the middle are calculated and used as waveform information.   [00061]   In addition, at the time of this wave editing, a new sub function

Move on. In step W6, the cross graphic is moved to the main graphic area MAIN GRA.
Cursor CAR is displayed, and a cross is displayed in the cursor value display field CAR VALUE.
The position information of the intersection of the cursor CAR is displayed.   [00067]   Then, the process proceeds to the next step W7, in which the switch 6-2 of the operator 6-1 is turned on.
Judge whether or not. If it is not turned on, the process returns to step W1 again.
If NO is determined in the step W7, the process proceeds to the next step W8, and the
Display MOUSE is displayed, and the process proceeds to the next step W9, at which the switch of the operation element 6-1 is switched.
It is detected whether the switch 6-2 is continuously in the on state, and it is detected that the switch is in the off state.
Then, the process proceeds to step W10 to determine the position of the mouse display MOUSE.
In both cases, the CPU 2 reads the value of the X-axis at that time, and furthermore, displays the value of the cross cursor CAR.
Fixes the X axis display. Then, in step W11, the switch of the operation element 6-1 is switched.
It is determined whether 6-2 has been turned on.   [00068]   If it is not turned on again, the process returns to step W10 and the mouse display MOU
The position of the SE is determined and displayed in accordance with the operation of the operation element 6-1. At this time the cross car
The Y axis of the Sol CAR moves, but the X axis remains fixed as described above.   [00069]   When it is detected in step W11 that the switch 6-2 has been turned on,
Then, the process proceeds to step W12, where the value of the Y-axis of the cursor is read, and
Is stored and displayed on the display device 10 as a new waveform sample point.
The contents of the display register 9 are rewritten.   [00007]   Thus, when the switch 6-2 is turned on and off once, the mouse display M
Stores the OUSE position on the X axis (X coordinate) and determines the address to be rewritten
. Then, by turning on and off the next switch 6-2, the mouse display body MOUSE is turned on.
