IX. ADSR Function
With this function you can create your own original sounds.

How the sound variations are formed:
Generally, a tone (character of a sound) is determined by pitch, loudness (strength) and timber (tone color).  Also in addition to the three elements mentioned above, there is another important factor for determination of a tone; so called "envelope" (the characteristic of the attack and decay of a sound).  In short, the change in loudness (amplitude) with the passage of time (duration).  For instance, a sound that slowly builds in loudness such as a violin.  Another example would be a sound that of a guitar where the loudness peaks momentarily when you pick the string and then reduces quickly.  These and many other sound wave variations are possible.  The illustration shows the envelope of a piano.  The graph shows the time (duration) horizontally and the amplitude vertically.  This is called an "envelope curve".  The ADSR function affects 5 elements (Attack, Decay, Sustain level, Sustain time, Release time) in determining the envelope curve and creates many sound wave variations.

ADSR is an acronym for the 5 elements
A: Attack time
D: Decay time
SL: Sustain level
ST: Sustain time
R: Release time
{diagram; ADSR}

How To Set And Use:
1. Let's form an 8 digit number to create a sound.
In the following paragraphs the numbers 0 to 9 will be used to determine the sound to be created.  8 numbers must be set in sequence.

a. Sound Waves - The following fundamental sound wave variations are available.
0 = Piano
1 = Fantasy
2 = Violin
3 = Flute
4 = Guitar 1
5 = Guitar 2
6 = English horn
7 = Electro-Sound 1
8 = Electro-Sound 2
9 = Electro-Sound 3

* For the items b through f on the right, the greater the number value (0-9) the greater the effect on the values illustrated on the graph.
b. Attack Time
c. Decay Time
d. Sustain Level
e. Sustain Time
f. Release Time

{diagram; ADSR}
References:
b - A small value of b creates a fast rise time making a sharp sound.
c, d and e - A large value of c, d and e creates the sound of long duration such as that of a flute or organ.
Smaller numbers create sounds of shorter duration such as that of a guitar or koto.
f - A large value of f causes an echo effect even after you release the key.

* For the next two items a greater value causes a greater effect.  A "0" means no effect.
g - Vibrato - The pitch will vary at a high rate.
h - Tremolo - The volume will vary  at a high rate.

EXAMPLE: "61079130"
This series of numbers would create the sound wave variations of English horn.  The sound wave variations are shown on the graph.
{diagram; 61079130}

2. How To Store 8 Digits
The 8-digit number determined in Paragraph 1 (page 22) can be stored in the memory as follows:

1) Set the mode selector to CAL.
2) Set the sound selector to ADSR.
3) Press the [MC] key.
4) Press 8 numbers in sequence as shown in Paragraph 1.
CAUTION: If the first number is "0" that number will be ignored.
EXAMPLE: "02357806" = "2357806"; "00872850" = "872850"
5) Press the [M+] key.
6) Set the mode selector to PLAY or REC.
Now you can enjoy one key play, auto play or manual play with the ADSR sound.

Some examples of ADSR compositions:
Violin: 23099130
Piano: 00453200
Synthe-sounds: 70099924
Flute: 33099130
English horn: 61079130

X. Melody Demonstration

If you set the mode selector to PLAY or REC and then press the [MUSIC] key the "German Folk Song" will be played automatically.  The sounds and rhythms vary during the playing to cause a very pleasing demonstration.

A Standard tempo is set at (4).  You can change the tempo freely while playing by simply pressing the [[TEMPO]] keys.

The melody will be repeated 4 times and then will stop.  If you want to stop it during play simply press the [MUSIC] or [RESET] key.
