CHAPTER 1
SETTING UP
Unpacking and Inspection
Your S4 Plus was packed carefully at the factory. The shipping carton was designed
to protect the unit during shipping. Please retain this container in the highly unlikely
event that you need to return the S4 Plus for servicing.
Upon receiving the S4 Plus, carefully examine the shipping carton and its contents for
any sign of physical damage that may have occurred in transit. If you detect any
damage, do not destroy any of the packing material or the carton, and immediately
notify the carrier of a possible claim for damage. Damage claims must be made by
you. Contact your Alesis dealer.
The shipping carton should contain the following items:
S4 Plus with the same serial number as shown on shipping carton
AC Power Supply
Computer floppy disk containing Sound Bridge software and electronic manual
This instruction manual, plus lists of Mixes and Programs, and Quick Start guide
Alesis warranty card
J
It is important to register your purchase; if you have not already filled out your
warranty card and mailed it back to Alesis, please take the time to do so now.
AC Power Hookup
The S4 Plus works with the voltage of the country it is shipped to (either 110 or 220V,
50 or 60 Hz), and comes with a line cord or power supply suitable for the destination
to which the keyboard is shipped.
Check the label on the AC adapter to ensure that the “input voltage” is correct for
your area. Insert the AC adapter's smaller plug into the 9V AC Power jack on the S4
Plus’s rear panel. Then plug the AC adapter itself into a source of AC power,
preferably a power strip with its own on/off switch. Alesis recommends turning off
power to the supply or unplugging it when the S4 Plus is not in use, to prolong its life.
Use only the AC adapter supplied with the S4 Plus; use of any other adapter will void
your warranty.
J
Alesis cannot be responsible for problems caused by using the S4 Plus or any
associated equipment with improper AC wiring.

Line Conditioners and Protectors
Although the S4 Plus is designed to tolerate typical voltage variations, in today’s
world the voltage coming from the AC line may contain spikes or transients that can
possibly stress your gear and, over time, cause a failure. There are three main ways
to protect against this, listed in ascending order of cost and complexity:
Line spike/surge protectors. Relatively inexpensive, these are designed to protect
against strong surges and spikes, acting somewhat like fuses in that they need to
be replaced if they’ve been hit by an extremely strong spike.
Line filters. These generally combine spike/surge protection with filters that
remove some line noise (dimmer hash, transients from other appliances, etc.).
Uninterruptible power supply (UPS). This is the most sophisticated option. A UPS
provides power even if the AC power line fails completely. Intended for computer
applications, a UPS allows you to complete an orderly shutdown of a computer
system in the event of a power outage, and the isolation it provides from the
power line minimizes all forms of interference—spikes, noise, etc.

About Audio Cables
The connections between the S4 Plus and your studio are your music’s lifeline, so
use only high quality cables. These should be low-capacitance shielded cables with a
stranded (not solid) internal conductor and a low-resistance shield. Although quality
cables cost more, they do make a difference. Route cables to the S4 Plus correctly
by observing the following precautions:
Do not bundle audio cables with AC power cords.
Avoid running audio cables near sources of electromagnetic interference such as
transformers, monitors, computers, etc.
Do not place cables where they can be stepped on. Stepping on a cable may not
cause immediate damage, but it can compress the insulation between the center
conductor and shield (degrading performance) or reduce the cable’s reliability.
Avoid twisting the cable or having it make sharp, right angle turns.
Never unplug a cable by pulling on the wire itself. Always unplug by firmly
grasping the body of the plug and pulling directly outward.
Although Alesis does not endorse any specific product, chemicals such as Tweek
and Cramolin, when applied to electrical connectors, are claimed to improve the
electrical contact between connectors.
Basic Audio Hookup
J
When connecting audio cables and/or turning power on and off, make sure that all
devices in your system are turned off and the volume controls are turned down.
Because the S4 Plus includes extensive signal processing as well as a full
complement of sounds, you can make great sounds with nothing more than an
amplifier or a set of headphones.
The S4 Plus has two Main and two Aux audio outputs. These can provide an
amplification system or mixer with several different audio hookup options:
Mono. Connect a mono cord from the [MAIN–R] Audio Output to a mono
amplification system or individual mixer input.
Stereo. Connect two mono cords from the [MAIN–L] and [MAIN–R] Audio
Outputs to a stereo amplification system or two mixer inputs.
Dual Stereo/Four Individual Outs. Connect two mono cords from the [MAIN–L]
and [MAIN–R] Audio Outputs and two mono cords from the [AUX–L] and [AUX
R] Outputs to a dual stereo amplification system, or four mixer inputs.
Stereo Headphones . Plug a set of high-quality stereo headphones into the rear
panel [PHONES] jack.

10 S4 Plus Reference Manual
A Word About Sound Bridge
Included with the S4 Plus is a 3-1/2" floppy disk containing a software program called
Sound Bridge. This software has been provided free of charge in an effort to promote
sound design for the S4 Plus.
Sound Bridge is a Macintosh™ sound development utility which compiles custom
samples from a variety of sources into the S4 Voice format, and downloads the
compiled data to an Alesis PCMCIA Sound Card via MIDI Sysex to an S4 Plus or S4
Plus. Originally developed for in-house use only, Alesis soon realized the need for
individuals and sound developers to be able to burn their own Sound Cards as well,
using whatever samples they wanted. Sound Bridge makes this possible without
having a PCMCIA card burner attached to your computer. All you need is an S4 Plus
or S4 Plus.
Sound Bridge creates an S4 Voice (multi-sample) by loading Sample Cell I or Sample
Cell II format Instrument files. Using this format, Sound Bridge is able to determine
key group and velocity group split points, root notes, sample playback rates, tunings,
start points, loop points, and loop tunings. Sound Bridge can also create S4 Voices
without Sample Cell Instruments by loading single AIFF, Sound Designer, or Sound
Designer II files.
Sound Bridge does NOT require Sample Cell hardware. The Sample Cell Instrument
file, or sample file, may be loaded directly into Sound Bridge from any disk (i.e. CD-
ROM, floppy disk, hard disk, etc.). For example, a user may load data from a Sample
Cell CD-ROM, and send this data to the S4 PCMCIA Card, without ever using
Sample Cell!
Sound Bridge can write to PCMCIA cards (or PC Cards) of up to 8MB in size. These
cards must be either Type I SRAM (150ns or faster) or Type I Flash RAM cards
(AMD C-series or D-series 5V Flash Memory Cards). If you are unsure whether a
card is compatible with the S4 Plus, contact Alesis Product Support for more
information.
The Sound Bridge disk contains the Sound Bridge application, and an electronic
manual which will give you all the information you need to know to run Sound Bridge.

Realtime Performance Functions
The S4 Plus provides various ways to control the sound as you are playing. Try out
some of these functions while playing your MIDI keyboard. The sound of the effects
can also change by using these controllers. The effect of these realtime controllers
varies from Program to Program; in some they may not be active, and in others they
may have a dramatic effect.
Velocity. The volume and tonal quality of the sound will change according to how
hard you play the keyboard.
Aftertouch. The action of pressing a key down after playing it is called
“aftertouch” (it is also sometimes referred to as “Pressure” since it corresponds to
the amount of pressure being applied to the keyboard). Pitch, tone and volume
(among other things) can be changed using aftertouch.
Pitch Bend Wheel. While playing a note, you can move the PITCH BEND
WHEEL up to raise the pitch, or down to lower the pitch. The amount of pitch
bend available can be different for each Program.
Modulation Wheel. By raising the MODULATION WHEEL, you can add
expressive modulation effects (such as vibrato or tremolo) while you play. The
type of modulation effect can be different for each Program.
The Quad Knobs. These are described below.
Further expressive control is available with a pedal switch or expression pedal. By
using a sustain pedal connected to your master MIDI keyboard, you can have the S4
Plus’ sound sustain even after you release the keys. By connecting an expression
pedal to your master MIDI keyboard, you can use the pedal to change the volume or
tone (or some other quality such as reverb depth or vibrato speed) of the sound, if the
Program is edited to use the pedal(s).
The Quad Knobs
To the right of the display are four knobs referred to as Quad Knobs, [1]—[4], each
with its own button. The Quad Knobs provide control over various parameters
depending on the mode you are in. The parameters in the display will change
depending on which function and page are selected. Not all four Quad Knobs are
active in all windows; there are many pages that have only one active Quad Knob.
These Controllers are defined in Global Edit Mode (Page 3) to transmit various MIDI
controller messages. If a Program or Mix uses these Controllers A–D, a pair of
arrows will point towards the active controller’s letter in the display. This indicates that
moving the related Quad Knob will have some kind of effect on the selected Program
or Mix. In the illustration below, Controller A (Quad Knob [1]) is used by the selected
Program.
1 234
When in Program Edit Mode or Mix Edit , the Quad Knobs are linked to the
parameters that appear in the right side of the display. The lower line of the
alphanumeric display will show the abbreviated name of each parameter, with a bar
graph below it representing the current setting of the parameter. By turning Quad
Chapter 2: Your First Session With The S4 Plus
16 S4 Plus Reference Manual
Knob [1], you adjust the setting of the first parameter on the left. Turning Quad Knob
[2] adjusts the next parameter, and so on. Once a Quad Knob has been turned, or its
button has been pressed, the top line of the display will immediately show the
parameter’s name and current setting. At this point, the parameter will have a thick
underline beneath its bargraph, indicating that you can now use the VALUE [¨] and
[Æ] buttons to adjust the parameter’s setting.
Auditioning Mix Play Mode
Mix Play Mode allows you to assign a Program to each of the 16 MIDI channels. This
makes it easy to create multitimbral setups for use with an external MIDI sequencer.
Additionally, a MIX can be used to “layer” sounds together, or “split” the keyboard in a
number of ways, or any combination of these. There are many different ways to
program a Mix. For more about Mix Play Mode, refer to Chapter 5. For more about
connecting the S4 Plus to a MIDI sequencer, see Chapter 3.
¿ Press the [MIX] button.
The display will change to Mix Play Mode.
¡ Select a Mix from 00—99 using one of these methods:

Setting the Effects Level
Each Program can use up to four Sounds, for either layering or splitting the keyboard.
Each of these Sounds has its own effects send level and effects bus assignment.
Many of the Programs in the S4 Plus use only one or two Sound layers, while others
may use all four Sounds. You can adjust the effect send amount for each Sound
independently, or you can view/edit all four sounds simultaneously.

Basic MIDI Hookup
MIDI is an internationally-accepted protocol that allows musical-related data to be
conveyed from one device to another. See the MIDI Supplement in Appendix B if you
are not familiar with how MIDI works.
The MIDI connections provide three different functions. To trigger the S4 Plus from a
MIDI control device (such as a master keyboard, drum pad, guitar or bass controller,
sequencer, etc.), connect the control device’s MIDI OUT to the S4 Plus’ MIDI IN.
MIDI OUT
MIDI IN
The MIDI THRU jack carries a replica (or echo) of the signal appearing at the S4
Plus’ MIDI IN, allowing you to trigger other devices from the same controller which is
feeding the S4 Plus. Simply connect the S4 Plus’ MIDI THRU to the other device’s
MIDI IN. Note that the MIDI THRU jack will not send messages from the S4 Plus’
keyboard itself.
MIDI OUT
MIDI IN
MIDI IN
MIDI THRU
The MIDI OUT sends MIDI data from the S4 Plus to other MIDI devices. This can
include
System Exclusive
data (see the MIDI supplement) which can be sent to a
storage device such as a MIDI librarian software program for later recall, or to
transfer data to another S4 Plus.
Chapter 3: Connections
20 S4 Plus Reference Manual
Using the S4 in Live Performance
Depending on the capabilities of your MIDI controller keyboard, you have two
different options available for how the S4 Plus will respond when it is in Mix Play
Mode:
If your controller can only issue commands on one or two MIDI channels
simultaneously, you may want to set the S4 Plus’ “Mix Group Channel”
parameter (on page 2 of the Global display) to a channel between 1 and 16, so
that your controller can play a mix of several S4 Plus Programs in response to a
single channel of MIDI.
If you have a master controller or QuadraSynth which can send on multiple MIDI
channels, you may want to set the S4 Plus’ “Mix Group Channel” to “Off”. To
create layers or stacks, your controller must send multiple MIDI messages to the
S4 Plus simultaneously. This offers you the added control of changing the sound
from the controller by sending Program Change commands on individual
channels within a Mix. A disadvantage of this approach is that the controller
must send many channels of duplicate MIDI messages simultaneously.
Note:
In Program Play Mode, the Mix Group Channel parameter has no effect. For
more information about the Mix Group Channel parameter, see pages 41, 44 and
112.
Connections: Chapter 3
S4 Plus Reference Manual 21
Using an External Sequencer
The MIDI keyboard or controller (such as the QuadraSynth Plus) can generate MIDI
signals that are recorded by a sequencer. On playback, the sequencer sends this
data back into the S4 Plus, which then serves as a multitimbral sound module (in Mix
Mode). The sequencer can generate data over several channels; in Mix Mode, the S4
Plus can be programmed so that individual Programs play sequenced data on
specific channels.
Example:
If the sequencer transmits a piano part over channel 1, a bass part over
channel 2, and a drum part over channel 10, you could set up a S4 Plus Mix so that a
piano sound plays only the MIDI data assigned to channel 1, a bass sound plays only
the MIDI data assigned to channel 2, and drums play only the MIDI data assigned to
channel 10. The S4 Plus can store up to 100 User Mixes.
Connect your master keyboard’s MIDI Out to the sequencer’s MIDI In (if using a
computer-based sequencer, connect to the computer’s MIDI interface’s MIDI In).
Connect the sequencer’s MIDI Out to your keyboard’s MIDI In. Finally, connect your
keyboard’s MIDI Thru to the S4 Plus’s MIDI IN (the Thru signal carries a replica of
what appears at the keyboard’s MIDI In, which is the same as the sequencer’s MIDI
Out).
Note:
It is not necessary to connect the S4 Plus’s MIDI OUT to the sequencer,
although doing so allows the S4 Plus to send data to the computer (such as System
Exclusive data to be stored into a librarian program).
MIDI THRU
MIDI IN

COMPUTER
MIDI
INTERFACE
MIDI IN
If you are driving other MIDI gear (such as an expander module or MIDI-responsive
signal processor), you’ll usually drive these from the sequencer if it has additional
MIDI outputs. However, you can also use the S4 Plus’s MIDI THRU connector to
drive other modules since the Thru carries a replica of what appears at the S4 Plus’s
MIDI IN, which is the same as the sequencer’s MIDI OUT.
Note:
For most sequencer applications, the S4 Plus’ “Mix Group Channel” parameter
(on page 2 of the Global display) should be set to OFF. See page 112 for more
information.
Chapter 3: Connections
22 S4 Plus Reference Manual
Digital Audio/Optical Hookup
The S4 Plus can send digital audio directly into ADAT, which provides better fidelity
than using the analog inputs and outputs.
The digital I/O connector follows a proprietary Alesis format that carries all four audio
outputs on a single fiber optic cable. Either pair of outputs can be converted into
standard AES/EBU or S/PDIF stereo digital audio format by using the Alesis AI-1
interface. Fiber optic cables of various lengths are available from your Alesis dealer.
The shorter the cable, the better. The model OC cable is 5 meters long and is the
maximum length recommended.
To hook up the optical cable:
¿ Remove the two pieces of clear plastic, tubular sleeving (if present) that protect
the tips of the optical cable plugs.
¡ Insert one cable end into the S4 Plus DIGITAL OUT and the other end into the
ADAT or AI-1 DIGITAL IN.
To test the cable and S4 Plus digital output, plug one cable end into the S4 Plus. The
other end should emit a soft red light (it is not dangerous to look directly at this light).
Recording Digital Audio
Once the fiber optic connection is made between the S4 Plus and ADAT or an AI-1,
the S4 Plus will output audio on the first four channels of the digital bus (the bus is
capable of handling eight channels of digital audio). The Main Left and Right outputs
are routed to channels 1 and 2, while the Aux Left and Right outputs are routed to
channels 3 and 4. Note that the volume knob controls the level of all analog and
digital output channels simultaneously. Set the volume to maximum for most
applications.
48 kHz Clock In
If your ADAT system has an Alesis BRC Remote Controller, the S4 Plus’s digital
clock must be synchronized to the clock coming from the BRC. Connect a BNC-to-
BNC cable (such as the Alesis BN cable) between the BRC’s 48 kHz CLOCK OUT
and the S4 Plus’s 48 kHz CLOCK IN. For more information about using the 48 kHz
clock, see page 118 in Chapter 8. When using only one ADAT without the BRC, it is
not necessary to connect the 48 kHz Clock.

S4 Plus Reference Manual 23
CHAPTER 4
OVERVIEW
Basic Architecture
The S4 Plus contains digitized acoustic and electronic voices, organized into 18
groups of sound types. The groups are:
Piano Bass Ensemble Drums
Organ Guitar Ethnic Percussion
Keyboard Brass Voice Rhythm
Synth Woodwind Sound FX QSPlus
Waves String
Several functions (filter, amplitude envelope, pitch envelope, LFO, multiple
modulation sources, signal processors, etc.) can be used to process a sample. A
Sound is the combination of a sample with its associated processing.
A Program consists of up to four sounds. These sounds can be layered, split over
specific keyboard ranges, or selectively overlapped. The S4 Plus has a User Bank of
128 Programs that you can modify, plus 4 Preset Banks with 512 Preset Programs
that are permanently installed in the S4 Plus at the factory (although the Preset
Programs can be edited, they must be stored into the User bank to permanently
retain your changes). Each Program is linked to its own Effects Patch.
A Mix consists of up to 16 Programs, each assigned to a specific MIDI channel and
one Effect Patch. The S4 Plus has 100 Mixes in the User Bank, plus 4 Preset Banks
with 400 Preset Mixes. This is extremely useful for multitimbral setups where the S4
Plus plays back different sounds on different MIDI channels. Because of the 64
voices and built-in effects, the S4 Plus is often the only sound generator needed.
S4 Plus Polyphony
The S4 Plus provides 64-voice polyphony (i.e., how many notes can play at once). If
a program uses one sound, up to 64 notes can play at once. Layering two sounds
allows for 32-note polyphony and layering four sounds, 16-note polyphony.
Layering is a powerful technique that allows you to build up complex timbres. This is
crucial because acoustic instruments have extremely complex, evolving sounds and
by comparison, many synths sound static. Being able to layer up to four sounds
allows for creating large ensembles (e.g., brass section consisting of alto & tenor sax,
trumpet, and trombone) or extremely realistic versions of single instruments. When
creating layered Programs, keep polyphony in mind. If all Programs in a Mix use all
four available sounds, the S4 Plus will quickly run out of voices.
Chapter 4: Overview
24 S4 Plus Reference Manual
Modes
The S4 Plus is always in one of two main modes: Program Mode or Mix Mode.
Pressing [PROGRAM] selects Program Play Mode, while pressing [MIX] selects Mix
Play Mode. While in Program Play Mode, you can press [SELECT] to access
Program Edit Mode and Effects Edit Mode. While in Mix Play Mode, pressing
[SELECT] alternates between Mix Edit Mode, Program Edit Mode and Effects Edit
Mode. Pressing [GLOBAL] accesses Global Edit Mode, pressing [COMPARE]
accesses Compare Mode, and pressing [STORE] accesses Store Mode. Here are
descriptions of these modes:
Program Play Mode
Program Play Mode lets you play the S4 Plus’s various Programs one at a time. The
S4 Plus
contains 512 Preset and 128 User
Programs
(i.e., the sounds of various
instruments, effects, ensembles, etc.) that show off just how cool this instrument
really is. Initially, the 4 Preset Banks and the User Bank contain data loaded in at the
factory. The User Programs can be edited or replaced with your own Programs.
However, you cannot replace the Preset Programs, because these are stored in
ROM (permanent memory). In Program Play Mode, the S4 Plus responds to or
generates messages on a single MIDI channel.
Mix Play Mode
Mix Play Mode lets you audition the S4 Plus’s various Mixes, and use it as a MIDI
master controller. The S4 Plus contains 400 Preset Mixes and 100 User Mixes. A Mix
can combine up to 16 different Programs, and the keyboard can generate up to 16
channels of MIDI data at once. Therefore, much thicker and richly textured sounds
can be created. In Mix Play Mode, the S4 Plus can be used in a wide range of
applications. It can be used for live performance, in which sounds are layered or
assigned to sections of the keyboard. It can also be used as a multitimbral sound
source for desktop music and home studio applications. A Mix can use the Effects
Patch associated with one of its Programs. Although there may be 16 Programs in a
Mix, there can only be one Effects Patch per Mix. In Mix Mode, the S4 Plus can
respond to messages on up to 16 MIDI channels simultaneously; different channels
are available depending on which Mix is selected.
Program Edit Mode
In Program Edit Mode, you can change the various settings which determine the
sound of an individual Program, or create an entirely new Program from scratch.
Each Program is made up of four Sound layers, which you can edit individually, or
simultaneously. In Program Edit mode you can:
select which sample waveform from the 24 megabytes of onboard sample ROM
will be used, in each of the 4 sounds;
change the tone, level, attack and decay characteristics, modulation inputs, and
pitch of each layer;
set modulation routings so any parameter can be controlled via MIDI;
set the effect level for each Sound layer, and set which of the four effect sends
each Sound layer will use for signal processing (such as reverb, delay, and
chorus—or any combination of these).
Mix Edit Mode
Mix Edit Mode lets you change the parameters of an existing Mix. Up to 16 Programs
can be active in each Mix, and Mix Edit mode sets up how each will be played. Mix
Edit Mode allows you to:
Overview: Chapter 4
S4 Plus Reference Manual 25
select which Programs will be played by the different MIDI channels and by the
keyboard in multiple layers or splits;
set the output level, effects level, and pan of each Program in the Mix;
select which Program’s Effects Patch will be used by the Mix.
Effects Edit Mode
Effects Edit Mode is used for setting up the Digital Signal Processing effects. Each
Effect Patch has 4 effect bus inputs, and an internal configuration of multiple effects
such as reverb, delay, and pitch-related effects (chorus, flange, etc.). You can
determine what kinds of effects are used on each bus (this is called a
“Configuration”), change each effect’s parameters (such as reverb decay time or
chorus speed), set modulation routings (such as having the modulation wheel change
the decay time), and set the effects mix (how much reverb, delay and chorus on the
output of each effect bus).
Global Edit Mode
Use Global Edit Mode to set various parameters which effect the entire instrument,
such as overall master tuning, display contrast, MIDI controller settings, keyboard
sensitivity, and how the unit will respond to or generate messages in Mix Mode.
Store Mode
Store Mode is used for storing changes of Programs, Mixes and/or Effects into the
User Bank or onto a QuadraCard PCMCIA memory card accessory. It is also used for
transmitting the S4 Plus’s parameters over MIDI for data storage purposes, copying
sounds or effects from one Program to another, and for transferring entire Banks to or
from a Sound Card.
Compare Mode
Once a Program has been edited in Program Edit Mode, or a Mix has been edited in
Mix Edit Mode, the word “EDITED” will appear in the display next to the Mix/Program
number. If [COMPARE] is pressed, the word “COMPARE” will appear in the display,
and you will temporarily be hearing (and seeing) the original version of the
Mix/Program. If you are editing a Mix and press [COMPARE], the original unedited
MIX is temporarily recalled. Likewise, if you are editing a Program or its Effects Patch
and press [COMPARE], the original Program will be temporarily recalled. Pressing
[COMPARE] again switches back to the edited version, and the word “COMPARE”
disappears from the display.

the four Sounds/sends. When Edit 4 mode is selected (press [EDIT 4]), all four
numbers appear, to indicate that all four Sounds are available for simultaneous
editing (Edit 4 mode is available in Program Edit mode only).
Functions list. Displays the various editing functions available in a particular
editing mode. Use the FUNCTION [¨] and [Æ] buttons to select a function, as
indicated by the small line (cursor) underneath one of the words in the list. When
a function is chosen, the page number strip and right-hand side of the display will
show values related to that function. Only the functions used by the current edit
mode will be displayed and selectable. Functions can also be selected from the
DIRECT SELECT buttons (see page 31).
Page number strip. Some functions have too many options to fit on a single
screen. These functions use multiple screens, with each screen considered a
page
. This strip shows which page is selected by underlining the page number.
The PAGE [¨] and [Æ] buttons allow you to select a page.
Overview: Chapter 4
S4 Plus Reference Manual 27
Name strip. When in Mix Play Mode, the name of the currently selected Mix will
appear here. Likewise, when in Program Play Mode, the name of the currently
selected Program will appear here. In any Edit mode or Store mode, the name of
the currently selected parameter will appear here indicating it is selected for
editing using the VALUE [¨] and [Æ] buttons.
Quad Knob/Button Label strip. This line is used to show the labels of the bar
graph meters, which determine the functions of the four Quad Knobs and
Buttons. These labels change depending on which function and page is currently
selected. The labels are abbreviations of the parameters; the complete name
(and value) of a selected parameter will appear in the Name strip.
Quad Knob bar graph meters. When a Quad Knob controls a function’s
parameter, an associated bar graph appears which reflects the Knob’s setting.
Note:
Not all four Quad Knobs are active in all pages. If a single line appears
somewhere in the bargraph area, it indicates its corresponding Quad Knob is
active.
MIDI Buttons
The MIDI [¨] and [Æ] buttons serve two purposes. In Program Play Mode, they select the
basic MIDI channel the S4 Plus will receive and transmit MIDI messages on. In Mix Play
Mode, they are used to select one of the 16 Channels for viewing and editing.
For more information on MIDI and its uses, see Chapters 8 and 9, and Appendix B.
Quad Knob Editing
The Quad Knobs have two editing modes: Immediate and Pass-thru. When using the
Quad Knobs to adjust parameter values, you may prefer using one mode over the
other. When set to Immediate, parameter values jump immediately to the Quad
Knob’s exact position the moment it is moved. When set to Pass-thru, the Quad Knob
must be turned beyond the parameter’s current setting before it becomes “live” and
begins adjusting the parameter’s value.
The editing mode is set in Global Edit mode, Page 2, using Quad Knob [3]. For more
information about selecting the Quad Knobs’ editing mode, see Chapter 8.
Chapter 4: Overview
28 S4 Plus Reference Manual
Parameter Editing
All parameter editing involves the same general procedure, with minor variations:
¿ Select the type of parameters you want to edit with the corresponding button:
[MIX], [PROGRAM], or [GLOBAL].
Mix parameters edit a Mix. Program parameters edit a Program. Effects
parameters can be edited from within a Mix or a Program (see below). Global
parameters edit general characteristics that affect the entire instrument.
¡ Select an Edit Mode with the [SELECT] button.
Example: If you pressed
[PROGRAM]
, the
[SELECT]
button switches between
two groups of functions—one for editing the Program’s Sound layers(Program
Edit Mode), and the other for editing the associated Effect (Effects Edit Mode). If
you’re editing a Mix, the
[SELECT]
button switches between three groups of
functions—one for editing the Mix’s parameters (Mix Edit Mode), one for editing
the Programs in the Mix (Program Edit Mode), and the last for editing the
associated Effect (Effects Edit Mode)
.
¬ Use the FUNCTION [¨] and [Æ] buttons to select a function (level, pitch, etc.).
Press
FUNCTION [Æ]
to advance through the list, and
FUNCTION [¨]
to move
backwards. The selected function will be underlined in the display. Press both
FUNCTION [¨]
and
[Æ]
simultaneously to get back to the first function in the list.
÷ If a function has multiple pages, select the appropriate page by using the PAGE
[¨] and [Æ] buttons.
The LCD’s page number strip shows the number of pages in a function; an
underline shows the currently selected page (e.g., if the display shows “1 2 3” then
page two is selected).
Press the
PAGE [Æ]
button to select the next higher-numbered page, and
PAGE
]
to select the next lower-numbered page. Press both
PAGE [¨]
and
[Æ]
simultaneously to get back to the first page of the selected function.
ƒ Select a parameter on the page for editing.
There can be up to four editable parameters on a page. The right side of the
display shows these parameters with both text and bar graph meters to give
instant visual feedback concerning a parameter’s value. Each of the four columns
has an associated Quad Knob and Button: the leftmost column monitors
Quad
Knob/Button[1]
, the second from left column monitors
Quad Knob/Button [2]
, etc.
Turning a Quad Knob or pressing its Button selects the associated parameter for
editing. The currently selected parameter is indicated by a thick line at the
bottom of one of the four bar graph meters.
ª Change the parameter value.
You can edit the value either by turning the associated Quad Knob (for large
value changes) or pressing the
VALUE [¨]
and
[Æ]
buttons (for smaller changes).
Each bar graph indicates a parameter’s approximate value—increasing a value raises
the column height. With
bipolar
values that can go positive or negative, turning a knob
clockwise increases the column height upward from the midpoint, and turning a knob
counterclockwise increases the column height downward (more negative value) from
the midpoint.
Always refer to the parameter name strip in the display above the bargraphs for the
current parameter label and value.
