Congratulations on your acquisition of a Yamaha SPX50D Digital Sound Processor! The SPX50D is a remarkably versatile digital sound processor that can be used by guitarists, keyboard players, home recording enthusiasts, mixing engineers — anyone involved with music. It offers a selection of 50 top-quality effects including digital reverberation, gated reverb, echo, flange, phase and a group of superb distortion effects. The distortion effects actually combine distortion with other effects (reverb, flange, etc.) for extraordinary sound

processing versatility. In addition to the 50 preprogrammed memory locations, there are 50

“user memory locations” which can be used to store your own edited versions of the preset effect programs, so you can recall your own effect creations anytime they are necessary. There's even an INSERT loop that allows you to switch a second signal processor unit into and out of the SPX50D signal path by simply pressing a button. The SPX50D is also MIDI compatible so you can select effects via remote MIDI control.

In order to fully take advantage of all the capability offered by the SPX50D, we urge you to

read this operation manual thoroughly. . ,

PRECAUTIONS

1. AVOID EXCESSIVE HEAT, HUMIDITY, DUST

AND VIBRATION

Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity — such as near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation or vibration which could cause mechanical damage.

2. AVOID PHYSICAL SHOCKS

Strong physical shocks to the unit can cause damage.

Handle it with care.

3. DO NOT OPEN THE CASE OR ATTEMPT

REPAIRS OR MODIFICATIONS YOURSELF

This product contains no user-serviceable parts. Refer all

maintenance to qualified Yamaha service personnel. Open ing the case and/or tampering with the internal circuitry will

void the warranty.

4. MAKE SURE POWER IS OFF BEFORE MAKING

OR REMOVING CONNECTIONS

Always turn the power OFF prior to connecting or discon

necting cables. This is important to prevent damage to the unit itself as well as other connected equipment.

5. HANDLE CABLES CAREFULLY

Always plug and unplug cables — including the AC cord — by gripping the connector, not the cord.

6. CLEAN WITH A SOFT DRY CLOTH

Never use solvents such as benzine or thinner to clean the unit. Wipe clean with a soft, dry cloth.

7. ALWAYS USE THE CORRECT POWER SUPPLY

Make sure that the power supply voltage specified on the rear panel matches your local AC mains supply.

8. ELECTRICAL INTERFERENCE

Since the SPX50D contains digital circuitry, it may cause interference and noise if placed too close to TV sets, radios or similar equipment. If such a problem does occur, move the SPX50D further away from the affected equipment.

9. BACKUP, BATTERY

The SPX50D contains a long-life lithium battery which main tains the contents of the buffer and user memory locations even when the unit is turned OFF. With normal use the battery should last for approximately 5 years. If the battery voltage falls below the safe level, however, the "*** WARN

ING *** LOW BATTERY” display will appear on the LCD when the power is first turned ON. If this occurs, have the battery replaced by a qualified Yamaha service center. Do not attempt to replace the battery yourself!

1: CONTROLS AND CONNECTIONS

/ THE FRONT PANEL /

O POWER Switch

Press the POWER switch once to turn power ON, a second

time to turn power OFF

O INPUT LEVEL Control

This control should be used in conjunction with the INPUT

LEVEL meter (see below) to set the optimum input level for

the source used.

0 INPUT LEVEL Meter

The input level meter consists of seven LEDs corresponding to -30 dB, -20 dB, -15 dB. -10 dB -6 dB. -3 dB and 0 dB Input

level. When the source (instrument or other) is connected to

the SPXSOD’s inputs, it should be played at the loudest level

It will be played during actual use and the INPUT LEVEL control adjusted so that the maximum reading is about -3 dB.

O LED MEMORY Number Display

This 2-digit numeric display shows the number of the' cur rently selected memory location (1 — 00). When the LED display Is continuously lit the effect corresponding to the number displayed is active. When the LED display Is flash ing, this indicates that a new memory location has been selected but has not yet been recalled, leaving the previ ously selected effect active.

O LCD (Liquid Crystal Display)

This 16-character x 2-line liquid crystal display panel nor

mally displays the title of the selected effect on the top line

and a selected parameter and Its value on the bottom line. One or both lines may also be used to display error mes sages or warnings.

e PARAMETER Button

This button is pressed to access the various parameters which can be edited within each effect. Each press on the PARAMETER button selects the next parameter on the "list” for the selected effect. When the parameter mode Is se lected, the parameter button LED will light.

0 Increment/Decrement Buttons

These buttons are used to select memory locations when the

memory selection mode is active (after the MEMORY button has been pressed), or to change parameter values when parameters are selected for editing (after the PARAMETER button has been pressed). The A and V buttons are also used to program several UTILITY functions.

0 STORE Button

This button is used to store edited effect parameters into one

of the user memory locations between 51 and 00.

0 RECALL Button

When a new memory location number has been selected

using the A and V buttons, the RECALL button must be

pressed to activate the selected effect.

0 COMPARE Button

The COMPARE button Is used In the PARAMETER mode to compare the sound of an edited parameter with that of the

parameter before it was changed. When the COMPARE button is pressed, the pre-edit parameter value is temporarily recalled and the COMPARE button LED will light. Press the COMPARE button again to return to the edited parameter value.

@ MEMORY Button

Pressing this button engages the memory selection mode, allowing a new memory location to be selected using the and V buttons. When the memory mode is selected, the memory button LED will light.

0 INSERT Button

The INSERT button activates the SPX50D INSERT IN/OUT

loop, adding a second signal processor connected to the

INSERT IN and OUT jacks to the effect chain. The INSERT ON/OFF status for each memory location can be memorized and recalled whenever that memory location Is selected. The

INSERT loop is active when the INSERT button LED Is lit.

® UTILITY Button

This button accesses a list of utility functions allowing editing

of effect titles, MIDI control programming and increment

footswitch recall range programming.

Direct Recall Buttons (REV/DLY Group, MOD & OTHERS, DIST Group)

These buttons provide fast direct access to the SPXSOD’s three major effect groups.

® BYPASS Button

The BYPASS button switches the selected effect ON or OFF, leaving the direct signal only when BYPASS is active.

® TUNER OUT Jack

The TUNER OUT jack can be connected directly to an elec tronic guitar tuner allowing convenient tuning without the

need to unplug your instrument from the SPX50D input and

connect it to the tuner.

® TRIGGER Button

When the TRIGGER button is pressed and its LED indicator

is lit, a footswitch plugged into the rear-panel MEM./TRG. FOOT SW jack can be used to trigger three of the SPXSOD’s effects: ADR-Noise Gate, Reverb & Gate, and Triggered Pan. Press the TRIGGER button a second time to restore

the foot switch’s normal memory selection function.

® INPUT Jack

Your instrument or other audio-signal source can be con

nected here or to the duplicate INPUT jack provided on the rear panel. The front-panel INPUT jack takes priority, so if sources are plugged into both the front- and rear-panel IN PUTS, only the front-panel INPUT will be active. The INPUT accepts a mono 1/4” phone plug, and is unbalanced.

/ THE CONNECTOR PANEL?

O MIDI IN Connector

MIDI signals from external MIDI devices can be fed to this

terminal to remotely select effects, set the pitch shift of the

PITCH CHANGE A effect, and trigger some other effects.

0 MIDI THRU Connector

The MIDI THRU connector simply re-transmits any data re ceived at the MIDI IN connector, permitting convenient “chaining” of MIDI devices.

@ BYPASS FOOT SW Jack

An optional Yamaha FC5 footswitch or equivalent connected

to this jack can be used for foot control of the BYPASS function.

o MEM./TRG. FOOT SW Jack

An optional Yamaha FC5 footswitch or equivalent can be

used to sequentially select any group of effects from the 100

available memory locations, permitting a sequence of effects

to be set up to match the flow of a live performance. When

the TRIGGER button is pressed and its LED indicator is lit, the footswitch can be used to trigger three of the SPXSOD’s effects; ADR-Noise Gate, Reverb & Gate, and Triggered

Pan.

o R & L OUTPUT Jacks

These two rhonayral 1/4" phone jacks deliver the stereo out

put signal from the SPX50D to subsequent amplification or mixing equipment. These jacks can be connected directly to

the inputs of guitar amplifiers, keyboard amplifiers, recording

equipment or mixing consoles. Since many of the SPX50D effects are true stereo effects, we recommend connecting both output jacks to the corresponding inputs of a stereo or two-channel sound system in order to get the best possible sound. If this is not possible, connect either of the OUTPUT jacks (L or R) to the amplification equipment used.

@ INSERT IN and OUT Jacks

The INSERT IN and OUT jacks allow connection of a second signal processor to the SPX50D which can be activated or

bypassed by using the INSERT button.

e INPUT Jack

The rear-panel INPUT jack duplicates the function of the

front-panel INPUT jack. Either — but not both — can be

used to receive the signal from your instrument or other audio signal source. The front-panel INPUT jack takes prior ity, so if sources are plugged into both the front- and rearpanel INPUTS, only the front-panel INPUT will be active.

2: GENERAL OPERATION

/MEMORY CONFIGURATION /

The SPX50D has a total of 100 internal memory locations. Lo cations 1 through 50 are READ-ONLY MEMORY containing the 50 preset effect programs. These locations cannot be written to or changed in any way. The effect programs contained in

__________________________________

/USING THE DIRECT RECALL BUTTON^ / USING THE INSERT LOO^

The three direct recall buttons — REV/DLY Group, MOD & OTHERS, DIST Group — provide fast, easy access to pro grams in the SPXSOD’s major effect groups from either the MEMORY or PARAMETER modes.

REV/DLY Group:

MOD & OTHERS:

DIST Group:

To directiy recaii one of these groups, simpiy press the appro priate direct recaii button. Each subsequent press on that direct recaii button wiii recaii the next program in that group. If the

direct recaii button is pressed again when the last program in the group is reached, the first program in the group is recalied. Any programs that you edit from a specific group and store in the RAM memory area are included in the group, and can be seiected using the appropriate direct recaii button.

When a group is first seiected using one of the direct recall

buttons, the last program selected in that group is automati

cally recalled.

Programs 1 through 20 and useredited programs from this group.

Programs 21 through 35 and useredited programs from this group.

Programs 36 through 50 and useredited programs from this group.

An external signal processor — a foot-pedal type guitar effect unit, for examplp — can be connected to the SPX50D INSERT

IN and OUT jacks, and switched into the SPX50D signal path

by pressing the INSERT button. The INSERT OUT jack should be connected to the input of the external signal processor, and the signal processor’s output should be connected back to the INSERT IN jack. When the INSERT button is pressed and its LED lights, the external signal processor is switched into the SPX50D signal path, allowing both the SPX50D and the external signal proces sor to function simultaneously. Pressing the INSERT button a second time (causing its LED to go out) deactivates the external effect. , The ON/OFF statué of the INSERT loop can be stored in any of the RAM memory locations (50 — 00) simply by pressing the STORE button when the desired RAM memory location is se lected. When this is done, the INSERT loop will be turned ON or OFF automatically whenever that memory location is se lected.

■f In the MEMORY mode, the increment and decrement but

tons can be used to select a new memory location from one that was recalled using the direct recall buttons, but the

RECALL button must be pressed to activate the selected memory location.

/BYPASSING THE effect/

There are two ways to switch the selected effect in and out: ® with the control panel BYPASS switch and ® with a footswitch connected to the connector-panel BYPASS footswitch jack. An optional Yamaha FC5 Footswitch can be used for foot-bypass control. In either case — when the controlpanel BYPASS button or BYPASS footswitch is pressed — a bold, flashing letter “B” will appear in the upper right-hand corner of the LCD. While the "B” is visible the SPX50D effect is bypassed and the input signal is directly routed to the output terminals (i.e. the effect is OFF). Press the BYPASS button or footswitch a second time to turn the effect back ON.

NOTE: If you attempt to STORE the INSERT status in a ROM

memory location, the “ ¡k* READ ONLY ** MEM NO. 1-50 ” error message will appear on the display. Press any panel key to clear the error message.

ACCESSING & EDITING

l^[HE^ARAME]ERS^

Each of the SPX50D effects has a number of internal parame

ters which may be edited by you to create a sound that is

ideally suited to your own specific musical requirements. A

complete description of each effect and its parameters is given

in “3. DESCRIPTIONS OF THE EFFECTS & THEIR PARAME

TERS” ON PAGE 13. Using effect 01 (REV 1 HALL) as an

example, here’s how to access and edit effect parameters;

® Select and recall the effect to be edited (REV 1 HALL for this

example).

@ Press the PARAMETER button and the first of the selected

effect’s parameters will appear on the bottom line of the LCD. Each time the PARAMETER button is pressed, the next parameter on the selected effect’s “parameter list” will be called. With REV 1 HALL, for example, the following parameters are called in sequence:

Note that the first parameter in the list is returned to if the PARAMETER button is pressed after the last parameter (OUT LVL in this example) has been called.

Once the desired parameter has been called, its value is

edited by using the A and/or V buttons. The A button increases (increments) the value while the V button de

creases (decrements) the value. Either button can be held down for continuous incrementing or decrementing.

New value

In this way you can go through and edit any number of the parameters to create the sound you want. If, however, you

select and recall a new effect without first storing your ed

ited parameters in a memory location between 51 and 00, any changes you have made will be lost and will have to be re-programmed. If you want to keep an edited effect, use

the STORE operation described beiow.

USING THE COMPARE FUNCTION /

ie COMPARE button is used while editing parameters in the ftRAMETER mode to compare the sound of an edited paimeter with that of the parameter before it was changed.

then the COMPARE button is pressed, the pre-edit parameter

jiue is temporarily recalled and the COMPARE button LED ill light. Press the COMPARE button again to return to the

dited parameter value.

STORING EFFECTS /

1 order to store an edited effect for later recall you need to do

le following:

) After editing the effect, select a memory location between 51

and 00 by first pressing the MEMORY button and then using

the A and V buttons. Do not recall the selected memory

location. If no data has been previously stored in the se lected memory location the LCD will read “ *** NO DATA *** . ” If an edited program has previously be stored in the selected memory location, its title will be displayed on

the LCD.

® Press the STORE button to store the edited effect in the

selected memory location. The title of the effect stored will appear on the LCD (this may later be edited to create your own effect title using the UTILITY mode EDIT TITLE func

tion). The LED memory number display will stop flashing and

the stored memory location will become the active effect.

NOTE: You CANNOT store edited data to memory locations 1

through 50. If you attempt to do this the LCD will show "*** READ ONLY*** MEM NO. 1—50”.

NOTE: Once an effect has been stored in an memory location

between 51 and 00, its parameters can be further ed

ited in the new memory location. Such changes will be lost if a different effect is selected and recalled, how ever, unless the STORE function is used to store the

changes. Changes may be stored to the current mem ory location number (51 — 00) simply by pressing the

STORE button.

3: DESCRIPTIONS OF THE EFFECT PROGRAMS

& THEIR PARAMETERS

/THE BALANCE AND OUTPUT /

/ LEVEL PARAMETERS /

Since all of the SPX50D effects have the same BALANCE and OUT LVL (Output Level) parameters, we’ll describe them here and leave them out of the descriptions of each effect that follow. BALANCE and OUT LVL are normally the last two para meters called in an effect’s parameter list.

Effect/Direct Signal Balance (BALANCE): 0 — 100%

This parameter adjusts the balance between the direct sound of your instrument (or other source) and the effect signal. At 100% only the effect sound is delivered from the SPX50D outputs, while at 0% only the direct sound is output. At a setting of 50%, the direct and effect sounds are output

in approximately equal proportions.

Effect Output Level (OUT LVL): 0 —100%

This parameter sets the output level of the effect. This is particularly handy for matching the levels between effects when setting up an effect sequence for a live performance.

-(TIME)

Reverb Time (REV TIME): 0.3 — 99 seconds

The length of time it takes for the level of reverberation at 1 kHz to decrease by 60 dB — virtually to silence. In a live setting, this depends on several factors: room size, room shape, type of reflective surfaces, and others.

High Frequency Reverb Time Ratio (HIGH): x0.1 — x1.0

Natural reverberation varies according to the frequency of the sound. The higher the frequency, the more sound tends to be absorbed by walls, furnishings and even air. This

parameter allows alteration of the high-frequency reverb time

in reiation to the overall reverb time.

Initial Delay (DELAY): 0.1 — 50 milliseconds

This parameter represents the delay between the direct

sound of an instrument and the first of the many reflections that together form reverberation.

High-pass Filter (HPF): THRU, 32 Hz --1000 Hz

Permits rolling off the the low-frequency content of the reverb signal below the set frequency. The HPF is OFF

when set to THRU.

Rev 10 Plate

Reverberation is the warm musical “ambience" you experience when listening to music in a hall or other properly-designed acoustic environment. The SPX50D offers ten different reverb effects, simulating types of reverberation you would experience in various halls (1 — 3), in smaller rooms (4 — 5), reverb effects ideally suited to vocals (6 — 8), and the type of reverberation produced artificially by a plate reverberator (9 — 10).

Low-pass Filter (LPF): 1 kHz —11 kHz, THRU

Permits rolling off the high-frequency content of the reverb signal above the set frequency. The LPF is OFF when set to THRU.

11. Early Ref. 1

16. Delay L, R

12. Early Ref. 2

13. Percussion E/R

14. Gate Reverb

15. Reverse Gate

These effects are created using different groupings of “eariy refiections” — the first ciuster of refiections that occurs after the direct sound but before the dense refiections that are known as reverberation begin.

Early Reflection Pattern (TYPE): HALL/RANDOM/REVERSE/ PLATE

The TYPE parameter selects one of four different patterns of

early reflections. HALL produces a typical grouping of early reflections that would occur in a performing environment

such as a hall. RANDOM produces an irregular series of

reflections that could not occur naturally. PLATE produces a

typical grouping of refiections that would occur in a plate

reverb unit. REVERSE generates a series of reflections that increase in level — like the effect produced by playing a recorded reverberation sound backwards.

The stereo delay effect offers independently variable left and right channel delays.

Rch F.B

Sets the time between the direct sound of the instrument and the first repeat heard from the left channel.

Room Size (ROOM SIZE): 0.1 — 20

This parameter sets the time intervals between the early re

flections — a feature of natural early reflections which is

directly proportional to the size of the room.

Liveness (LIVENESS): 0 — 10

Tiveness” refers to the rate at which the reflected sounds

fade. An acoustically “dead” room is simulated by setting this

parameter to zero. Increasing the value of this parameter creates an increasingly “live” sound, simulating an increas ing area of reflective surfaces in the room.

Delay (DELAY): 0.1 — 400 milliseconds

The time delay between the direct sound of the instrument and the first of the early reflections.

Low-pass Filter (LPF): 1 kHz — 11 kHz, THRU

Permits rolling off the high-frequency content of the early reflection signal above the set frequency. The LPF is OFF

when set to THRU.

Left Channel Feedback Gain (Lch F.B): -99% — +99%

Sets the amount of the left-channel delay signal fed back to

the input of the processor. The higher the feedback gain setting, the greater the number of delayed repeats pro duced.

Right Channel Delay (Rch DLY): 0.1 — 500 milliseconds

Sets the time between the direct sound of the instrument and

the first repeat heard from the right channel.

Right Channel Feedback Gain (Rch F.B): -99% — +99%

Sets the amount of the right-channel delay signal fed back

to the input of the processor. The higher the feedback gain setting, the greater the number of delayed repeats produced.

High Frequency Feedback (HIGH): xO.1 — xl.O

Controls feedback in the high-frequency range. The high-

frequency feedback is reduced as the value of this parame ter is decreased.

This sets the basic delay time from the initial direct sound to the beginning of the flange effect.

Feedback Gain (F.B. GAIN): 0% — 99%

Determines the amount of flange signal which is fed back to the input of the processor for further modulation. More feed back increases the overall complexity, “strength” and decay time of the effect.

Controls feedback in the high-frequency range. The highfrequency feedback is reduced as the value of this parame ter is decreasxed.

22. Chorus A

23. Chorus B

24. Chorus C

Like flanging, chorus serves to thicken the sound of an instru

ment, creating the effect of several instruments playing at once. The A and B chorus effects split the incoming signal into three signals placed at the center left and right of the stereo

image. The delay time and level of the three signals are then

modulated by the LFO (Low Frequency Oscillator). The Chorus

C effect sends the direct sound to the left channel and the

processed sound to the right channel.

AM DEPTH

. (TIME)

DM DEPTH

Modulation Frequency (MOD. FRQ): 0.1 Hz — 20 Hz

Sets the speed of the effect variation.

Modulation Depth (MOD. DEPTH): 0% —100%

28. ADR-Noise Gate

This program uses a “gate” to pass or shut off the input signal in a number of ways. It can be used to pass just a short seg

ment of a longer input signal, or it can be set up to pass only

signals that exceed a specified level. In the latter case this program functions as a “noise gate.” It is also possible to cre ate reverse gate type effects in which the gain increases gradually after the effect is triggered.

100%

(TIME)

Trigger Level (TRG. LEVEL): 1—100

Determines the level of the input signal required to trigger “opening” of the gate. At 100 only very high-level input sig nals will trigger the gate, while at 1 even the tiniest input signal will trigger the gate.

Hold Time (HOLD): 1 — 30,000 milliseconds

Determines how long the gate stays open, allowing the sig nal to pass at the DECAY LEVEL, after the first decay and prior to beginning of the RELEASE TIME.

Release Time (RELEASE): 5 — 32,000 milliseconds

Determines how long it takes for the gate to close fully after the HOLD TIME has ended.

MIDI Trigger (MIDI TRG.): OFF, ON

When this parameter is turned ON, a KEY ON EVENT mes sage .from an external MIDI keyboard can be used to trigger the gate. A KEY ON EVENT message is transmitted when ever a note on a MIDI keyboard is played.

NOTE: This effect can also be triggered by a footswitch

plugged into the rear-panel MEM./TRG. FOOT SW jack if the front-panel TRIGGER button LED is lit (press the TRIGGER button to activate or de-activate the footswitch trigger function).

Trigger Delay (TRG. PLY): -100 — +100 milliseconds

Produces a delay between the time at which the gate is

triggered and that at which it actually opens. If a minus value

is programmed, the input signal is delayed so that, effec

tively, the gate opens before the signal appears.

to fall to DECAY LEVEL after it is fully open.

Decay Level (DECAY LVL): 0 — 100%

Determines the level at which the gate remains open for the HOLD TIME. The lower the value, the lower the HOLD gate level.

29. Compressor

This extremely versatile compressor program allows creation of

a wide range of compression and limiting effects. It can simply be used to reduce the dynamic range of a signal, to smooth out the sound of an electric bass or add sustain to an electric guitar.

It can help to reduce volume fluctuations as a vocalist moves closer to or away from a microphone, or limit the maximum level

of a signal to prevent overloading certain types of amplification

of recording equipment.

Attack Time (ATTACK): 1 — 40 milliseconds

Determines how long it takes for full compression to be reached after the effect is triggered (i.e. the THRESHOLD level is exceeded). The right ATTACK setting is essential to preserve the natural initial attack sound of the instrument used — or modify it as desired.

Release Time (RELEASE): 10 — 2,000 milliseconds

Determines how long it takes for compression to be released after the input signal drops below the THRESHOLD level. The RELEASE setting is important to preserve the natural release sound of the instrument used. Too short a RE LEASE setting will cause the sound to be cut off unnaturally.

Threshold Level (THRESHOLD): -48 — -6 dB

Determines the level of the input signal at which the com pression effect begins. Set at a low level (-48 dB) all input signals will be compressed. At a higher level, only those signals exceeding the THRESHOLD level will be com pressed, thus producing a limiting effect. The THRESHOLD level must be set to match the level and characteristics of

the instrument being used, as well as the desired effect.

Delay Time (DELAY): 0.1 — 400 milliseconds

Determines the time delay between the direct sound and the

compressed effect sound.

Compression Ratio (RATIO): 1 — 20

This parameter sets the "amount” of compression applied to the input signal. A setting of 1.0 produces no compression, while a setting of 20 produces maximum compression.

Detect Delay (PET. PLY): -50 — +50 milliseconds

This parameter sets an initial delay between the time the input signal begins (the time the THRESHOLD level is ex ceeded) and the time the compression effect begins. This delay can be used to allow the initial attack of an instrument to come through completely unaffected while the rest of the signal is compressed. A minus DET DLY setting causes the compressed sound to appear before the direct instrument sound.

30. Reverb & Gate

This effect combines a reverb program with a gate program,

making it possibie to output only a segment of a ionger reverb

sound.

-(TIME)

Reverb Time (REV TIME): 0.3 — 99 seconds

The length of time it takes for the level of reverberation at 1 kHz to decrease by 60 dB.

High Frequency Reverb Time Ratio (HIGH): x0.1 — xO.1

This parameter allows alteration of the high-frequency

reverb time in reiation to the overall reverb time.

Initial Delay (DELAY): 0.1 — 50 milliseconds

This parameter represents the delay between the direct sound of an instrument and the first of the many reflections that together form reverberation.

High-pass Filter (HPF): THRU, 32 Hz —1000 Hz

Permits roiiing off the the low-frequency content of the reverb signal below the set frequency. The HPF is OFF when set to THRU.

Release Time (RELEASE): 5 — 32,000 milliseconds

This parameter determines the time it takes for the gate to close completely after the HOLD time has elapsed.

MIDI Trigger (MIDI TRG.): OFF, ON

When ON, a KEY ON EVENT message from a MIDI key board can be used to trigger the effect.

NOTE; This effect can also be triggered by a footswitch

plugged into the rear-panel MEM./TRG. FOOT SW

jack if the front-panel TRIGGER button LED is lit

(press the TRIGGER utton to activate or de-activate

thei footswitch trigger function).

31. Pitch A

This program can actually change the pitch of an input signal over a 2-octave range. The shifted pitch can be combined with the direct sound (by an appropriate setting of the BALANCE

parameter) to create automatic harmonies.

Pitch Shift (PITCH): -12 — +12

Sets the degree of pitch change in semitone steps. +12 cor

responds to an output pitch one octave higher than the input pitch, and -12 produces an output pitch one octave lower than the input pitch. An external MIDI keyboard can even be

used to select the desired degree of pitch shift.

Fine Tuning (FINE): -100 — +100

Permits extremely fine pitch adjustment in one-cent steps.

Low-pass Filter (LPF): 1 kHz — 11 kHz, THRU

Permits roiiing off the high-frequency content of the reverb signal above the set frequency. The LPF is OFF when set to THRU.

Trigger Level (TRG. LEVEL): 1 — 100

Determines the amplitude of the input signal required to trig ger opening of the gate. At 100 only high-level input signáis will trigger the gate, whiie at 1 even the siightest input signai wiii trigger the gate.

Hold Time (HOLD): 1 — 30,000 milliseconds

This parameter sets the amount of time the gate is “open,” aiiowing the reverb sound to come through.

Delay Time (DELAY): 0.1 — 400 milliseconds

Sets the delay between the direct sound (input signal) and the pitch-shifted output signal.

Feedback Gain (F.B. GAIN): 0 — 99%

When this parameter is set to 0, only a single pitch-shifted sound is produced after the DELAY time has elapsed. As the value of this parameter is increased, however, more and more delayed repeats are produced, each pitch-shifted up or down from the previous repeat according to the setting of the PITCH parameter.

32. Pitch B

Base Key (BASE KEY): OFF, C1 — C6

This parameter sets the “BASE KEY” for an external MIDI synthesizer used to control the PITCH parameter (the MIDI OUT terminal of the synthesizer must be connected to the SPX50D MIDI IN terminal, and the SPX50D must be set to

receive on the MIDI channel on which the synthesizer is transmitting). If, for example, the BASE KEY parameter is set to C4, pressing the C3 key on the synthesizer (C3 is one octave lower than C4) will set the pitch change value to -12.

Pressing D4 on the keyboard would produce a pitch in crease of one whole-tone (+2). If a key more than an octave

higher or lower than the BASE KEY is pressed, the resultant

pitch change setting will still be within the -12 to +12 range,

as shown in the illustration below. If the BASE KEY parame ter is set OFF, pitch cannot be controlled via the MIDI IN terminal.

In this program, however, the two pitch-shifted notes are inde pendently fed to the left and right channel outputs (the direct sound is positioned at the center of the stereo sound field) for a

true stereo harmony effect.

4: UTILITY FUNCTIONS

The SPX50D UTILITY button provides access to a number of important functions. Each press on the UTILITY button ad vances to the next function until the UTILITY mode is exited:

TITLE EDIT - MIDI CONTROL -» MIDI PRO CHANGE F.SW MEMORY RCL - exit UTILITY

mode.

/ TITLE EDIT /

This function makes it possible to create original titles for pro grams you edit and store in memory locations 51 through 00. The TITLE EDIT function is the first one to appear when the UTILITY button is pressed. The "TITLE EDIT” function name appears on the bottom line of the LCD, and an underline cursor appears at the first character position on the top line. The MEMORY and STORE buttons are used to move the cursor back and forth, while the A and V buttons are used to select a new character for the current cursor position. Simply move

the cursor to each character position in turn, selecting the ap

propriate characters at each position. The available characters are as follows;

/MIDI BANK & CHANNEL ASSIGNMEt^

The SPX50D makes it possible to select specific programs via external MIDI control. You can set up the SPX50D, for example, so that when you select a voice on your synthesizer the most appropriate effect for that voice is automatically selected. This is accomplished because each time you select a voice on your MIDI synthesizer it transmits the corresponding MIDI PRO

GRAM CHANGE NUMBER. The SPX50D receives this PRO GRAM CHANGE NUMBER and selects the effect program that you have assigned to it using the MIDI PROG CHANGE func tion which will be described below. The SPX50D also accepts MIDI KEY ON EVENT messages to trigger some of the gate effects, and MIDI KEY ON NUMBERS to set the PITCH pa rameter of the Pitch A effect. The SPX50D actually can be programmed with four completely independent sets of MIDI PROGRAM CHANGE NUMBER/MEMORY NUMBER assign ments. Each of these is contained in a different “bank”: A, B, C or D. Each BANK may also be programmed to receive on a different MIDI channel. An example of the way the four banks may be programmed with different receive channels and pro gram number/memory number assignments is given below:

-Receive channel

BANK: A

^ PH 1

PGM 1 = MEM 1

PGM 2 = MEM 4 PGM 2 = MEM 7 PGM 3 = MEM 8 PGM 3 = MEM 16

PGMJ28 = MEM,40

Memory number of SPX50D

BANK: C

CH = 15

PGM 1 = MEM 90 PGM 1 = MEM 1 PGM 2 = MEM 89 PGM 2 = MEM 2 PGM 3 = MEM 88 PGM 3 = MEM 3

BANK: B

CH = 2

PGM 1 = MEM 6

PGM 128 = MEM 1

BANK: D

CH = OMNI

PGM 128 = MEM 40

PGM 128 = MEM 38

(D Press the MEMORY button to return to the BANK parame

ter if you wish to select a different bank for programming.

® Press the UTILITY button until the MIDI PROG CHANGE

function appears (MIDI PROG CHANGE is the third func tion on the UTILITY “list”).

® Use the A and ▼ buttons to select the program change

number to which a new SPXSOD memory location number is to be assigned. The range of available program change numbers is from 1 to 128.

@ Press the STORE button to move the cursor to the MEM

(memory number) parameter.

® Use the A and V buttons to select the memory location

number containing the effect which is to be assigned to the currently selected program change number.

Press the MEMORY button to return the cursor to the PGM (program number) parameter in order to select a new pro gram change number for effect assignment.

/FOOTSWITCH MEMORY RECALL RANGE /

NOTE: The program number/memory number assignments

made are stored in the BANK selected in the previous MIDI CONTROL function. To program the program change/memory number assignments for a different BANK, return to the MIDI CONTROL mode, select the desired BANK, then program the required assign ments.

The SPX50D permits memory selection via an optional Yamaha FC4 or FC5 footswitch connected to the rear-panel MEMORY footswitch jack. The fourth function accessed by the UTILITY button — F.SW MEMORY RCL — permits setting the range of memory location numbers that will be selected when the footswitch is pressed.

F.SW MEMORY RANGE 51 TO

If, for example, the RANGE parameter is set to “51 TO 55” as

shown in the LCD illustration above, each time the footswitch is

pressed the next highest memory location will be selected until

the last number in the specified range is reached. After the last

number in the specified range, the first (lowest) number is se lected and the process repeated. Reverse sequences can be programmed by entering the highest number in the range be

fore the lowest, as shown below.

F.SW
