DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention
Can synthesize musical sounds using combination tones
The present invention relates to a tone synthesizer. [0002] 2. Description of the Related Art Tone synthesizer using waveform data reading method
Usually selects one tone from multiple tones
Therefore, it is possible to synthesize a musical tone with the tone. 1
The basic timbre data that defines one timbre is one waveform
Use when synthesizing musical tones using data and its waveform data.
Tone control parameters (eg, EG (envelope
Generator) parameters, volume level, frequency characteristics
Multiple associated parameters, such as defining filter coefficients) and
Consists of Below, such basic tone data
The timbre specified by the basic timbre data is called timbre data.
Called the basic tone. [0003] Further, conventionally, the pronunciation fool in the basic tone has been
Rather than arbitrarily combining multiple basic tones
Different bases depending on the playing style, such as
A `` combination tone '' that can be pronounced in the actual tone
There are known tone synthesis devices that can be used. [0004] By the way, the combination
Tones are simply divided into multiple basic tones, for example, for each range.
Even if you hit it, the timbre change in the range direction becomes unnatural
Often. For example, the sound of a live piano is sampled for each range.
The ringed waveform is combined with the basic timbre data for each
And combine these basic tone data
When the sound is pronounced as a tone (when the pronunciation instruction comes at a certain pitch)
The basic tone data corresponding to the range to which the pitch belongs.
Pronounced), natural in all key ranges like a live piano
To reproduce a continuous tone change, it is attached to each basic tone
Tone control parameters such as volume level and frequency response
Adjustment is required. Each basic tone data is
Since it is set so that it is properly pronounced only in the area,
For example, the sound set in the basic tone data of the first range
Quantitative level and basic timbre data of the second range adjacent to it
Is different from the volume level set in
The volume level becomes discontinuous at the boundary with the second range
This is because it may be. However, such tone control parameters
Adjustments are made for each basic tone data included in the combination tone.
The tone control parameters must be reset separately
However, there was a problem that it was very complicated and troublesome. Ma
In addition, by adjusting such parameters,
Tone control of basic tone data combined with data
The control parameters themselves have been changed, and
There were cases where there was a disadvantage when using only colors. Sa
In addition, if you want to diversify the tone, the simplest thing is
Editing a combination tone
Setting of tone control parameters for combination tones is complicated
And the original parameters themselves are changed by editing
There was the inconvenience of being done. [0006] The present invention is not only a basic tone,
In a tone synthesizer that can synthesize musical sounds even with
The timbre can be easily diversified.
When the parameters of the combined tone are changed, the
Be careful not to change the parameters themselves
The purpose is to do. [0007] SUMMARY OF THE INVENTION In order to achieve this object,

It may be used. In particular, DATASET-DE
When only SIGNATION is used, one waveform data
Summarizes the six parameters used when sounding data
Use the bank parameters or the basic tone parameters.
Parameters can be specified, making parameter setting simple.
It is simply user-friendly. On the other hand, selection flags
If DESIGNATION1-6 is used, one by one
Use bank side parameters for each parameter or basic sound
You can specify whether to use color-side parameters,
Parameter setting becomes possible. In addition, one flag
Only for all parameters according to the value of the flag.
To use the bank side or the basic tone side
You may make it so. Further, in the above example, the selection flag group DE
