Yamaha DX27 Electronic Keyboard User Manual


 
The following EG curves show the parameters for some common instruments.
20: OPERATOR OUT LEVEL
Permits setting the output level of the selected operator. The data range is from 0
to 99. At 0, the operator is OFF. A setting of 99 produces maximum output level
from the selected operator.
Varying the output level of an operator functioning as a carrier results in a change
in the overall level of the sound contributed to the voice by that operator. Varying
the output level of an operator functioning as a modulator results in a change in
the harmonic spectrum produced by the carrier, thereby changing the timbre of the
sound.
Data is entered using the DATA ENTRY slider or buttons.
21: RATE SCALING
This parameter makes it possible to gradually shorten the overall envelope length
(increase EG rate) as higher notes on the keyboard are played. This is particularly
useful for simulating the sound of stringed instruments such as piano or guitar, in
which the envelope of the higher notes is noticeably shorter than the lower notes.
