OUTLINE OF TONE PARAMETERS

UOUTLINE OF TONE PARAMETERS

1. THE BASIC CONCEPT OF ATONE

ATone consists of two Partials (Partials 1and 2) and aCommon

block.

Each Partial (Partial 1and Partial 2) can have one of two sound

generators (a Synthesizer sound source or aPCM sound source). So

you can think of the D-50 having powerful synthesizers built in.

Each of these hypothetical synthesizers could behave like a

conventional analog synthesizer, or aPCM sampled synthesizer. Any

combination of two synthesizers can achieve some remarkable cross

—modulation effects, so characteristic of today's purely digital

sounds.

Some Common parameters apply to both Partials (Partial 1and 2),

"Structure" is one of the Common parameters. It decides which of

the two sound generators is used for each Partial. Other Common

parameters are an ENV for pitch, three LFO modules, equalizer,

chorus, etc.

OUTLINE OF TONE PARAMETERS

[STRUCTURE] Structure, which is one of the Common parameters, determines which

two of the hypothetical synthesizers (a synthesizer sound generator

or aPCM sound generator) are to be used as Partial 1and Partial

A"Synthesizer sound generator" works like aconventional analog

type synthesizer with an oscillator, afilter, an amplifier and two

ENV's. APCM sound generator provides 100 different PCM sampled

sounds.

These two Partial sounds (Partial 1and Partial 2) can simply be

mixed as shown below.

Partial 1

Partial 2

By mixing two Partials, fatter sounds can be obtained. This is

effective for making strings or organ type sounds.

Or Partial 1can be mixed with the ring- modulated sound of

Partiais 1and 2.

OUTLINE OF TONE PARAMETERS

The Ring Modulator multiplies two sounds, creating an unusual and

metallic sound that contains complicated harmonics. For instance, two

waveforms (® and ©) are multipled and waveform ®is created.

This is effective for making metallic sounds.

2. STRUCTURE OF TONE PARAMETERS

Depending on which generators are selected in the Partial Block,

greatly different Tone Parameters will be used .Some Tone

Parameters used for the Synthesizer sound generators are irrelevant

to the PCM generator (see the diagram below).

In aStructure with Ring modulation, some parameters of Partial 2

are automatically set to those of Partial 1. See page 22 "Tone

Parameters" for adetailed explanation.

OUTLINE OF TONE PARAMETERS

a. WG (Wave Generator)

b. TVF (Time Variant Filter)

In the WG (Wave Generator), the pitch and waveform are controlled.

©Pitch

The basic pitch of aPartial (sound generator) can be set here.

The pitch is aCommon parameter, and is therefore controlled by

©P-ENV and ©LFO-1.

©Waveform (PCM Wave Number)

This selects the waveform of the sound source. When asynthesizer

sound generator is selected, the waveform can be controlled by the

©Pulse Width controls.

©Pulse Width

This changes the waveform of the sound source. The pulse width

is controlled by any LFO (=Common parameter).

This filter passes lower frequency harmonics and cuts off the higher

ones. By changing the cutoff point and the resonance, the waveform

changes.

©Cutoff Frequency

This sets the cutoff point. The cutoff point can be controlled by

©TVF ENV and any LFO (=Common parameter).

©Resonance

This emphasizes the cutoff point, making more unusual or electronic

sounds.

c. TVA (Time Variant Amplifier)

This controls the volume of the Partial.

DLevel

This determines the volume of the sound. When asynthesizer

sound generator is used, the level can be controlled with the ®

TVA ENV and any LFO (Common parameter). When aPCM sound

generator is used, the ©TVA ENV controls the level.

OUTLINE OF TONE PARAMETERS

d. ENV (Envelope Generator)

This generators acontrol signal (envelope curve) which controls the

pitch, timbre and volume of each Partial (sound generator).

©P-ENV

This is the ENV which controls pitch. It can be set for two

selected Partial at once.

®TVF ENV

This ENV controls the cutoff point, and can be set for each Partial

separately.

(DTVA ENV

This ENV controls the volume level. This can be set for each

Partial separately.

e. LFO (Low Frequency Oscillator)

This oscillator generates low frequencies only.

Any of the three LFO's can be used for the two Partials, Vibrato,

PWM growl or tremolo effects can be obtained using these LFO's.

*A different LFO can be used for each section or aPARTIAL.

®LFO-1

This can control ©Pitch, ©Pulse Width, ©Cutoff Frequency

or ©Level.

©LFO-2

This can control ©Pulse Width, ©Cutoff Frequency or ©Level,

©LFO-3

This can control ©Pulse Width, ©Cutoff Frequency or ©Level.

EDITING

21 EDITING

The D-50 features various parameters which can be edited, thereby-

synthesizing new sounds. However, it does not feature knobs or

switches on its front panel. Instead, there are two methods of

editing :one is achieved by calling each parameter with the relevant

buttons, and changing the value with the Joystick, or Increment and

Decrement Buttons, the other is by using the optional programmer

PG —1000, which has all the necessary panel controls.

For quicker and easier editing or synthesizing from scratch, the PG

—1000 may be essential.

*The editing procedure does not automatically rewrite the existing

program, the appropriate writing procedure, on page 18 must be taken.

1. CALLING APARAMETER

Anumber of Patch Factors and Tone Parameters are shown in a

Menu Display at the same time. There are several Menu Displays as

shown below. Each parameter shown in aMenu Display contains

EDITING

The following explains how each button works. The Menu Display

and parameter which each button leads to are shown in the supplied

Edit Map. Please thoroughly study the map.

•Selector Buttons

These can be used to select one of the parameters shown in the

Display. Simply push the relevant Selector Button, and its current

value will flash in the Display.

•Scroll Buttons

These buttons can be used to scroll through more parameters in

the same menu group.

Pushing the far —right Scroll Button calls the next parameter

group, and the left Scroll Button returns to the previous parameter

group.

•Exit Button

This button can be used to leave the parameter currently called

and go back to its Menu Display. To go back to the Play Mode

Display, hold down the Shift Key while pressing the Exit Button.

[CHANGING PARTIAL DISPLAYS]

While editing aparameter of one Partial, you can call the Display

of the same parameter for adifferent Partial.

The Patch Buttons 1to 4can select Partials as shown below.
