CHAPTER V: VOICE PROGRAMMING EXAMPLE
In this section we’ll go through the steps in creating a fairly percussive electric piano voice from scratch. This simple
example should help you understand the programming process.
STEP 1:
Initialize a Voice
Enter the FUNCTION mode (press FUNCTION button) and call the MEMORY
PROTECT function. Turn MEMORY PROTECT OFF.
Call INIT VOICE function and press the YES button twice. This initializes the voice
and automatically enters the EDIT mode. Select the ALGORITHM select parameter.
If you now play a note you will hear a sine wave.
Selecting the Algorithm
STEP 2: In this voice there are two distinct sound components: the main piano decay sound
and a percussive attack “ping.” For this purpose we’ll use algorithm 5, which has
two separate vertical “stacks” of two operators each.
The ALGORITHM parameter has already been called, so select algorithm 5 using
the DATA ENTRY controls.
STEP 3:
Turn Operators 3 and 4 OFF
We’ll start by programming the main piano sound using the left operator stack in
algorithm five—operators 1 and 2. Turn operators 3 and 4 OFF using the corre-
sponding OPERATOR/AMS ON-OFF buttons.
