3. The Voice
Parameters
The following is a brief description of each available voice parameter, how it is
programmed, and its effect. These parameters are selected by pressing the appro-
priately labelled (purple labels indicate voice parameters) button while the DX27
is in the EDIT mode.
PB MODE: OPERATOR SELECT
This switch (located immediately above the -1 DATA ENTRY button) selects the
operator to he worked on. Only one operator can be selected at a time. Only the
parameters for the selected operator will be displayed on the LCD panel.
In the EDIT mode, the currently selected operator number is displayed at the right
side of the LCD: for example, “OP3.” This only applies to parameters which can
be individually programmed for each operator. However, when parameters that affect
all operators simultaneously are called (the LFO WAVE, SPEED and DELAY pa-
rameters, for example), the current operator display will disappear from the LCD
and individual operators cannot be selected.
BANK A—D/OPERATOR/AMS “ON-OFF”
Individually turns operators 1 through 4 ON or OFF. In many cases, a voice will
not require all operators in an algorithm. Operators, that are not needed should
be turned OFF while editing. Also, during the voice creation process, it is a good
idea to start with all operators OFF and then turn them ON one at a time as you
program and add them to the algorithm. The four digits immediately preceding the
algorithm number on the LCD display represent the four operators, 1 through 4,
in order from left to right. When an operator is ON, a “1” appears in thecorresponding
position, and when an operator is OFF a “0” appears in the corresponding position.
Each press on the BANK A through D buttons alternately turns the corresponding
operator ON and OFF.
When the AMPLITUDE MODULATION SENSITIVITY parameter is selected (10),
these buttons are used to determine to which operators the sensitivity setting will
apply.
When the EG COPY function is in use (see page 38), these buttons are used to
select the operator to which the data from the currently selected operator will be
copied.
1: ALGORITHM
Permits selection of any of the 8 available algorithms. The desired algorithm number
is selected using either the DATA ENTRY slider, -1/+1 buttons, or the parameter
button.
