and light brown characters below the buttons for FUNC-

TION mode parameters. A brief example for two buttons
is shown here, with the specific references for these two

buttons noted in parentheses:

Violet EDIT mode parameters (Pitch and Amplitude

Modulation Sensitivity)

(E&F)

Brown FUNCTION mode parameters (SAVE all 32

voices from internal memory to cartridge, or LOAD 32

voices from cartridge to the internal memory)

To simplify the presentation, we have further sub-

divided these buttons into the EDIT (violet) and FUNC-

TION (brown) groupings. Therefore, if you don't see the

operational description that applies to what you're doing
with a particular button as you read through the para-
graphs on the EDIT parameters, check the correspond-

ing button in the FUNCTION parameter descriptions

(and vice-versa).

Edit Parameter Selection (violet labels)

OPERATOR ON/OFF-EG COPY (1-6)

These buttons have two functions, (a) to turn individ-

ual operators on and off while you are programming a
voice, and (b) to designate the operator into which you
wish to copy an envelope. When you are in the EDIT
mode, the top center portion of the LCD display shows 6

number 1's or 0's, corresponding to the 6 operators:

1 =ON, and 0=OFF To toggle operator's output on or

off, press the corresponding [OPERATOR ON-OFF]

button. To copy the envelope, set the operator whose

envelope you wish to copy as the current operator using

[OPERATOR SELECT], then press [STORE] and hold

it while pressing [EG.COPY] button for operator 1 to 6;

all 4 rates and levels are instantly copied.

ALGORITHM

In EDIT mode, this button activates the [DATA

ENTRY] section so its controls can be used to select any

of the 32 available algorithms.

FEEDBACK

In EDIT mode, this button activates the [DATA

ENTRY] section so its controls can be used to alter the

amount of feedback in whatever algorithm is displayed

from none (0) to a maximum value (7).

LFO

In EDIT mode, these 6 buttons each activate the

[DATA ENTRY] section so it can be used to program or
edit individual voices with regard to Low Frequency

Oscillator modulation. When the modulation is used to

change the pitch, vibrato can be obtained. When it is

used to change the amplitude of a carrier, tremolo may
result; changing the amplitude of a modulator can create

"wah-wah."

WAVE
This lets you set the LFO waveform to any of the

following: triangle, sawtooth down, sawtooth up,
square, sine, sample & hold.

SPEED

This lets you adjust the LFO frequency in a 100 step

range, 0 being the slowest and 99 the fastest.

DELAY

This lets you set the LFO so modulation does not
begin until after a specified time after you press the

key, 0 being no delay, and 99 the maximum delay.

PMD

This lets you set the Pitch Modulation Depth. This is
the amount of modulation that will be applied to shift
the pitch of whatever notes are played (according to
the set waveform and speed). However, the modula-

tion can only affect the note if the pitch modulation

sensitivity is set to a value greater than zero (see
[MOD SENSITIVITY-PITCH]).

AMD

Like PMD, this button lets you set the Amplitude

Modulation Depth, the amount of modulation that

will be applied when you play but it affects the
amplitude (level), not the pitch. Likewise, the modu-

lation can only affect the note if the Amplitude modu-
lation sensitivity is set to a value greater than zero
(see [MOD SENSITIVITY-AMPLITUDE]). The same

LFO speed and waveform controls both the [PMD]

and [AMD].

SYNC
This lets you turn on or off the LFO Key Synchroni-

zation. When Sync is ON, the LFO is automatically

reset to the beginning of the selected waveform each

time you play a note. When sync is OFF the LFO
waveform continues, and when you play a note, the

result will vary depending on where the LFO is in

the cycle. The effect can be easily detected at low
LFO frequencies (SPEED settings below 10).

MOD SENSITIVITY

In EDIT mode, this pair of buttons activate the [DATA

ENTRY] section so it can be used to set the sensitivity

of individual voices to LFO modulation. The modulation

sensitivity is like a master control for all the modulation,
whether it is "built into" the voice with the adjacent
[AMD] and/or [PMD] buttons, or whether it comes from
the "real time" modulation controls such as the Modula-

tion Wheel, the Foot Control, the Breath Control or the

keyboard After Touch. If the Pitch or Amplitude Modula-

tion Sensitivity is set at zero, then none of the external

controllers can affect the voice, regardless of how much

Depth is set with their FUNCTION mode controls.
