INTRODUCTION
The SL-2001 is a unique MIDI instrument which combines powerful master keyboard functions with versatile MIDI processing features Its operating system has been carefully designed for fast and efficient musical control ofany MIDI system, from small home studios to professional stage setups
The SL-2001 is like any musical instrument, the more time invested, the greater the rewards Once the basic principles of operation aie mastered, the many powerful functions are easily accessible It is not necessary to read and understand every detail of the SL-2001 operation guide, but please take the time to scan all of the sections to gain
awareness of the unit's full potential
Sections 1 through 4 contain essential information and should be read carefully Sections 5 through 8 aie reference sections which detail all of the powerful functions available, and may be studied as required.
1 QUICK REFERENCE
For basic operation please follow the guidelines below. The SL-2001 includes eight demonstration presets which may be used after the instrument is installed into your MIDI system.
1.Connect voltage adapter into a power outlet (make sure voltage specification on power adapter matches your line voltage). Connect adapter cable to SL-2001 power jack.
2.Connect MIDI cables before switching on any MIDI devices. To use the demonstration presets, connect a sound module to each of the four MIDI outputs A-D. Each sound module should be set to receive on MIDI channel 1.
4.Apply power to all MIDI devices in the system.
5.Switch on the power to the SL-2001.
To change SL-2001 presets, make sure that the unit is in Perform Mode (red light on EDIT switch is off). To change the preset, press any of the eight PRESET switches. To change to a different bank, press the left or right arrow switches
( < > ) until the desired bank number is displayed before pressing one of the eight PRESET switches. Presets are arranged in eight banks of eight, for a total of 64 presets (11 through 88). An optional memory card is available which holds 64 additional presets.
Local controllers (front panel sliders, Star and Alpha switches, footswitches A through C, and control voltage inputs 1 and 2) will issue MIDI control change commands depending on the selected preset.
MIDI devices may be switched on and off using the eight ZONE switches.
To edit a preset, enter Edit Mode by pressing the EDIT switch. Press the appropriate FUNCTION switch to access the desired function (press several times if necessary until the desired screen appears on the text display). If a star (*) appears in the display, an alternate screen may be accessed by pressing the Star switch. Adjust the parameter with the appropriate control slider. To change parameters for a specific zone, first select the appropriate zone by using the left and right arrow switches. The selected zone is indicated by the zone digit(s) following the preset number.
IMPORTANT: Before the SL-2001 can be "installed" into the SL-2001 operating system.
effectively programmed for your MIDI system, all MIDI devices must be properly Refer to the DEVICES function in section 4 for information on this procedure.
DEMONSTRATION PRESETS
The SL-2001 comes from the factory with 8 demonstration presets in locations 11 through 18. The demonstration presets are intended for use with four MIDI sound modules. Each sound module should be set for MIDI channel 1, and each should each be on a separate MIDI output. The demonstration presets illustrate several of the most useful SL-2001 functions, and are summarized below. When the demonstration presets are selected with the PRESET switches, the sound modules should change programs automatically. The actual program number on each sound module may not match the number of the preset selected on the SL-2001. These program numbers may be easily changed; see the operation guide sections on Edit Mode and the Program function.
DEMONSTRATION PRESET 11: All four sound modules are active and receiving note information from the keyboard. The ZONE switches may be used to turn off selected sound modules to hear different combinations of the modules. The four control sliders on the front panel are used to adjust the volume level for each sound module (refer to the CONTROLS function in section 8 for information on programming sliders and control pedals).
DEMONSTRATION PRESET 12: All four sound modules are active, but the keyboard is divided into four zones, with a different sound module active in each zone (refer to the ZONE function in section 8 for more information).
DEMONSTRATION PRESET 13: All four sound modules are active, but each key that is played on the keyboard is assigned to a different sound module, (refer to the NOTES function in section 8 for more information).
DEMONSTRATION PRESET 14: All four sound modules are active, but MIDI information for modules 2, 3, and 4 is delayed, with module 2 set for the shortest delay and module 4 set for the longest. The two wheel controllers may be used to change pitch or add modulation; this MIDI data will be delayed along with the note information, creating a unique effect (refer to the DELAY function in section 8 for more information).
DEMONSTRATION PRESET 15: This preset demonstrates the velocity switch function. For notes played softly on the keyboard, only the first sound module will play. As the keys are struck more forcefully, module 2, module 3, and finally module 4 will sound (refer to the VELOCITY function in section 8 for more information).
DEMONSTRATION PRESET l6: This preset uses only MIDI sound module numbers one and two, and demonstrates what is known as a velocity cross-fade. For notes played softly on the keyboard, only sound module number 1 should play at maximum volume. As the notes are struck more forcefully, sound module 1 will become softer, and sound module 2 will become louder (refer to the VELOCITY function in section 8 for more information).
DEMONSTRATION PRESET 17: This preset demonstrates MIDI delay combined with multiple key transpose settings to produce an arpeggio for every note that is played on the keyboard. Only sound module #1 is used in this preset. For best results, this module should be capable of playing eight or more notes simultaneously (refer to the TRANSPOSE function in section 8 for more information).
DEMONSTRATION PRESET 18: The SL-2001 is capable of generating long MIDI delays with independent time settings for each sound module. This preset has zero delay for the first sound module, and delays of 2.5, 5, and 7.5 seconds for the second, third, and fourth modules respectively.

2 BASIC INFORMATION
The SL-2001 MIDI Master Keyboard serves as the central controller for any group of MIDI instruments and accessories. With four MIDI inputs and outputs and powerful MIDI processing functions, the SL-2001 eliminates the need for outboard MIDI switchers or other devices. Full programmability means that your time is spent making music, not reconfiguring the equipment.
The SL-2001 will command at least eight sound modules (or keyboard synthesizers) simultaneously and at least eight auxiliary MIDI devices (audio effects units, mixers, lighting controllers, etc). More than thirty-two MIDI devices may be connected and selectively accessed under preset control. The four MIDI outputs are completely independent, which means that sixty-fourMIDIchannelsareavailable.
BACKPANELCONNECTIONS
MIDI INPUTS: Four MIDI inputs are provided to support several additional performance devices at once (other keyboards, guitar controllers, sequencers, etc). The MIDI data from any of these external sources may be processed and zoned in the same way as the master keyboard, or it may be passed straight through to any of the outputs.
MIDI OUTPUTS: The four MIDI outputs will support a large number of MIDI devices as each output may contain information on several MIDI channels simultaneously. A total of 64 slave devices are addressable under preset control.
SWITCH INPUTS: Three stereo phone jacks are provided for control footswitches. A double footswitch is included with the SL-2001, and will normally be connected to the SUSTAIN / A input. The SUSTAIN footswitch on the right will function as a conventional piano sustain pedal, while the A footswitch on the left may he programmed for a wide range ofMIDI functions. Its most commonly used function is to activate or disable one or more zones during a performance. An additional double footswitch may be purchased and may be used in either the B/C input or the (preset) increment/decrement input. Inputs B/C may be programmed to control zones, issue MIDI control changes, or other functions. For live performance, many players will want to use three double footswitches simultaneously, in order to effect quick sound changes while playing the keyboard.
Although stereo jacks are used for the switch inputs, a standard normally-open footswitch with a mono phone plug may also be used. It will function as either SUSTAIN, switch B , or program increment. If desired, the switch inputs may be used as voltage inputs. The voltage range is from 0 to 5 volts DC, with 0 volts corresponding to the footswitch being pressed.
CONTROL VOLTAGE INPUTS: Two inputs are provided for external analog controllers. An optional control pedal is avail-
able from your dealer, or any DC control voltage source may be used. The input voltage range is 0 to 5 volts DC, which corresponds to a MIDI control range of 0 to 7F hex. The control pedal is most commonly used to control volume.
MEMORY CARD
The SL-2001 is equipped with a connector for a plug-in memory card. The optional memory card is used to make back-up |
|||
copies of SL-2001 presets as well as giving quick access to an alternate set of presets. Use of a memory card for saving inter- |
|||
nal presets is strongly recommended. Before performing any Save or Load operation, be sure that the card is firmly inserted |
|||
into the connector as far as it will go. The card may only be inserted with the printed side facing up. |
When not in,use, store |
||
the memory cards in a safe place away from excessive heat or moisture. |
| |
: |
|
The memory card contains a battery which should be replaced after five years of use. The plastic clip which holds the bat- |
|||
tery may be removed by carefully pulling it from the end of the card (to the right of the memory-protect switch). The bat- |
|||
tery should only be removed when the memory card is inserted in a SL-2001 and power is applied, otherwise the data in the |
|||
card will be lost. Contact your dealer for replacement battenes. |

MIDI SYSTEM CONFIGURATION
The illustration (facing page) shows .a typical medium-sized MIDI system configured around the SL-2001. Most systems will |
|
include a combination of keyboard synthesizers, sound modules, and effects units. When using keyboards that produce |
|
sound (as opposed to a MIDI control keyboard), set the instrument to "local off mode. This will disconnect the sound-gen- |
/ |
erating circuitry from the keyboard. The instrument can now be considered as two devices: a controller keyboard with a |
/ |
MIDI output, and a sound module with a MIDI input (consult your operation manual for instructions on the "local off" mode). /' |
|
As many as four external keyboards may be connected and used as master controllers for the entire system. |
|
The sound modules should be distributed evenly among the four MIDI outputs to avoid congesting any MIDI lines with |
|
excess information. In the example, two sound modules have been cascaded on MIDI output C, and two effects units are |
|
sharing MIDI output D. When multiple units are on the same MIDI output, they must have unique MIDI receive channels, |
|
so that each can receive independent MIDI data from the SL-2001. The total number of MIDI channels per output must not |
|
exceed sixteen. If a sound module can receive all sixteen MIDI channels simultaneously, it cannot share a MIDI output with |
|
any other device. |
|
If there are more than four sound modules in your system, the MIDI-THRU jacks on each unit can be used to connect addi- |
|
tional sets of units. If more than twelve modules are used, it is a good idea to use a multiple-output MIDI-THRU box on each |
|
SL-2001 output. The SL-2001 can access up to 64 slave devices, without requiring any repatching of MIDI cables: |

MIDI CONFIGURATION
INSIDE THE SL-2001
The SL-2001 is very unique among MIDI keyboards. All of its powerful master controller functions are available from its own keyboard, or from any external MIDI keyboard. In addition, the SL-2001 also functions as a very versatile MIDI switcher, router, and processor, which eliminates the need for many outboard MIDI devices.
The diagram above depicts the internal structure of the instrument. There are four MIDI inputs and four MIDI outputs. Eight independent MIDI data processors link the keyboard and MIDI inputs to the MIDI outputs. Each processor can be programmed to receive data only from a specific region of the master keyboard or external keyboards; it is therefore convenient to refer to the processors as ZONE 1 through ZONE 8. MIDI information from
two or more zones can be merged (combined) into the same MIDI output. If desired, all eight zones may be merged into the same output, although the inherent speed limitation of the MIDI format may result in sluggish response.The configuration of the zones is programmable for every preset on the SL-2001. In general, each zone will be associated with one MIDI synthesizer connected to the MIDI outputs. In special cases, several zones will be processing MIDI data which will all be merged to the same MIDI output and received by a single sound module.
ZONES
The SL-2001 keyboard will send MIDI data to as many as eight instruments simultaneously (the instruments may be physically separate devices, or different MIDI channels of a multi-channel sound module). Each instrument receives MIDI data from one of the eight zones. The sophisticated MIDI processing performed by the zone allows very precise control over the sound and response of each instrument. The function of all eight zones is independently programmable in each of the sixtyfour SL-2001 presets.
The diagram above illustrates the internal structure of a zone. A MIDI message from a SL-2001 input port is received by all zones connected to that input. If the zone is not active (front panel ZONE switch is off), no further processing occurs. If the zone is not bypassed, an incoming message is checked to see that its channel matches the channel programmed into the zone's Channel Filter. If the channel does not match, the zone ignores the message.
If the channel is matched, the MIDI message continues through the zone. MIDI note messages are processed by many master control functions, which may modify the note number, velocity, or perform other sophisticated processing. MIDI controller messages may be passed unchanged, converted to a different controller message (mapped), or blocked completely. The resulting MIDI message is then assigned a specific MIDI channel, delayed (programmable from zero to ten seconds), and routed to one of the four MIDI outputs.
The zones are able to issue program change and controller initialization values (volume, modulation, etc.) at the instant a SL2001 preset is selected. These messages will be issued even if the ZONE switch is off. If the zone is activated later with a footswitch, the sound module will already be set for the proper program and controller
settings. Program and controller initialization messages may be enabled or disabled as discussed in section 8.
When the SL-2001 is used as a general-purpose MIDI switcher, a zone may be bypassed to allow all MIDI data to How from the zone's input to its output. The messages retain the same channel number as received. This mode is useful for sequencer applications, where data on all sixteen MIDI channels is passed as a group from a SL-2001 input to a SL-2001 output, (sys-
• tern-exclusive data is passed ONLY through bypassed zones). None of the processing or controller initialization functions are available when a zone is bypassed.
Regardless of zone mode, all note messages issued to the output are monitored. Whenever a zone is turned off, note-off messages are automatically issued to clear any sustained notes.
DEVICE NAMES
The SL-2001 offers simplified programming and operation by allowing all MIDI devices in the system to be designated by a five-character name. Before any programming begins, these names are entered into the SL-2001. While entering the device names, the user also specifies the MIDI port to which the device has been connected (MIDI IN A-D or MIDI OUT A-D) and the MIDI channel (1 through 16) on which the device is set. For all subsequent programming, devices are specified by name only; the port and channel are not required as they are implied by the name. For large MIDI systems in particular, this makes programming much more efficient as it relieves the musician of having to remember the port and channel number for each device.
Some synthesizers are multi-timbral, which means that they are able to produce several different sounds simultaneously, such as strings, organ, and piano sounds. Each of the sounds is controlled by information on a different MIDI channel. When used with the SL-2001, a multi-timbral instrument should actually be considered as more than one instrument, and each should have a unique name in the SL-2001 device list. For example, if sound module XYZ can produce two sounds independently, we can install two devices into the SL-2001: XYZ1 and XYZ2.
The SL-2001 master keyboard is represented by the device name "2001"; this name may not be edited or deleted. Be sure to consult section 4 to install device names before you attempt to program the SL-2001.
OPERATION
The SL-2001 front panel is designed for fast and efficient programming of all functions. Learning to operate the unit is very easy, as the large 48-character LCD text display assists by presenting function and parameter names which are usually selfexplanatory. In addition, all MIDI devices connected to the SL-2001 are designated by five-character names, which greatly simplifies programming of presets.
The Front Panel diagram identifies the various controls and display areas. There are only two operating modes: Perform Mode and Edit Mode. The front panel of the SL-2001 is color-coded to indicate the function of each control in Perform (gray labels) or Edit mode (blue labels).
The EDIT switch is used to select between Edit and Perform Modes (the red LED on the switch is lit in Edit mode). Edit mode is used to edit an existing SL-2001 preset or to create a new one. While in Edit mode, the SL-2001 is still active and performing MIDI data processing (although certain functions are inhibited which would interfere wdth the programming procedure). Once the presets have been programmed as desired, the unit should be switched to Perform Mode. The STORE switch is used to record an edited SL-2001 program into a specific preset location, or to copy presets from one location to another. The Store function can be used while in either Perform Mode or Edit mode.
A special All-Notes-Off function has been provided to clear any notes that become stuck on synthesizers and sound modules receivingdatafromtheSL-2001. PressingtheEDITandSTORE switches simultaneouslywill initiate a sequenceofmessages to the MIDI slave devices which should clear the stuck notes. Using the All-Notes-Off function will not change the current SL-2001 operation mode.
PERFORM MODE
During performance or recording sessions, the SL-2001 will normally remain in Perform Mode. While in Perform Mode, the text display presents very useful information regarding the current preset.
Preset Name: A 10-character label entered by the user that describes the current preset. internal memory or the card memory (if present). If the current preset resides in the appear in square brackets [preset name].
Presets may be selected either from memory card, the preset name will
Switches: Displays the status of the three general-purpose switches (controlled by the back-panel input jacks). If a switch is on, the switch letter (A, B, or C) will appear. If the switch is off, there will be a dash. Note that these letters indicate the cur-
rent state of the switch, which may not directly correspond to whether the footswitch is pressed. See section 7 for information on programming the switch modes and initial values.
Chain: If the chain function is being used, the selected chain (A through Z) will appear, followed by the current step number. If the selected chain has not been programmed, the step number will not appear.
csl 1 - csl 4: Labels selected.by the user to describe the function of the four control sliders in the preset. There are a total of twenty-four characters in this line. This area may alternately be used to display any other general information concerning the preset.
Preset Digits: There are sixty-four presets in the SL-2001 arranged in eight banks of eight presets. The optional memory card stores an additional sixty-four presets. Throughout this operation guide, the word preset refers to the storage location of the SL-2001. The word program refers to a particular sound setting of an external instrument. To call up a new preset, first use the left or right arrow switches to select the desired bank (if different from the current hank). The first display digit will change to the new bank, and the second digit will turn off. Next, use the eight PRESET switches to select the desired preset. The new preset will be loaded and the text display will change to reflect the new preset. If the Conditional Preset Change function (Section 6) is enabled, the SL-2001 preset will change only after all keys have been released from the keyboard and the sustain pedal is released. The new preset number will Hash until these conditions are met. If the Conditional function is off, any notes sounding on the MIDI sound modules will be turned off automatically before the preset is changed.
The SL-2001 presets are stored in non-volatile memory circuits powered by a lithium battery when the power is switched off. After several years of operation, the battery will need to be replaced. A warning message will appear on the LCD display if the battery voltage is too low. Contact your dealer for a replacement battery.
The sixty-four memory card programs are stored in eight banks of eight presets. The card program banks are stored consecutively with the internal banks. If you use the left or right arrow switches to select a bank number that is greater than eight or less than one, the SL-2001 will enter the card memory area. When one of the eight PRESET switches is pressed, the new card preset will be active. Card presets are denoted by square brackets around the preset name in the text display.
When receiving MIDI program change commands, the SL-2001 interprets program change numbers 0 through 63 as internal presets (11 through 88), and program change numbers 64 through 127 as card presets.
The ZONE switches indicate whether each zone is active or disabled. These switches may be pressed at any time to enable or disable a zone. Depending on the configuration of the preset, several zones may be sending MIDI information to the same sound module. To prevent notes from sounding on this module, it will be necessary to turn off all zones associated with the module. Any notes that are sounding when a zone is deactivated will be automatically turned off.
The two switches below the EDIT and STORE switches are the Star (*) and Alpha (a) switches. In Perform Mode, the function of these switches is fully programmable. They may be used to activate sound modules, send MIDI messages, or other functions.
EDITMODE
To edit a preset or create a new one, you must press the EDIT switch to enter Edit Mode (the red LED on the switch will light). All SL-2001 functions are arranged into eight groups. The desired group is selected with one ofthe eight FUNCTION switches.
Each time the function key is pressed, the text display will present the next function of the group. Each function contains from one to four parameters which may be changed with the corresponding control slider. Many of these parameters have a large number ofpossible values. In order to allow easy access, the values are divided into several groups. Adjacent groups of values are selected by moving the slider to the top or bottom end of its travel. To return to a previous group of values, reverse the direction of slider motion.
While in Edit Mode, some SL-2001 functions are disabled to prevent interference with programming procedures. MIDI control functions programmed for the four control sliders or the Star and Alpha switch are active only during Perform Mode. SL2001 preset changes (from any source) are also inhibited in Edit Mode.
FUNCTION TYPES
There are four categories of functions in the SL-2001. The categories are based on the programmability of the function.
NON-PROGRAMMABLE (function group I): These functions are not programmable. They are utility functions used to perform special operations that are occasionally needed, such as storing all presets to the memory card, or displaying MIDI data entering the SL-2001. When any function in this group is accessed, the Preset Digits turn off, indicating that the function is not associated with any particular SL-2001 preset. A complete description of the utility functions appears in section 5.
GLOBAL-PROGRAMMABLE (functiongroup 2): Functionsinthis'categoryhave parametersthatare globallyprogrammable, which means that there is only one set of values stored in memory. These values are not dependent on the preset that is selected; they are the same for all presets. All global-programmable parameter values are stored permanently in memory, even if power to the SL-2001 is switched off. Any time a Global-programmable parameter is changed, the new value is automatically saved in memory. The new value will remain in memory until edited again. There is no need to use the STORE switch to save Global settings; any changes are automatically updated.
The five-character names assigned to the MIDI devices in the system are examples ofglobal-programmable parameters; there is only one set ofnames which remains the same for all presets. Any time that a Global function is accessed, the Preset Digits turn offto indicate that the function is not associated with any specific SL-2001 preset. A complete description of Global-pro- grammable functions appears in section 6.
PRESET-PROGRAMMABLE (functiongroup 3): These functions contain parameterswhich can have differentvalues foreach SL-2001 preset. Any change in a Preset-programmable function must be stored into a preset location with the STORE switch.
The Preset Name is an example of a Preset-programmable function. A different name may be entered for every SL-2001 preset. When any Preset-programmable function is accessed, the Preset Digits indicate which preset is being modified. A complete description of all Preset-programmable functions appears in section 7.
ZONE-PROGRAMMABLE(functiongroups4through8): Thesefunctionscontainparametersthataredifferentforeachzone (as well as each preset). This means that every SL-2001 preset contains eight sets of parameters, one set for each of the eight zones. When editing these functions, you must choose a particular zone within the particular preset. The zone digit(s) will appear whenever a zone-programmable function is selected. To change the zone, use the left or right arrow switch. The Store function must be used to save any changes in zone parameters.
The MIDI delay setting is an example of a zone-programmable function. For every preset, each of the eight zones may be programmed for a different delay time (0 to 10 seconds). A complete description of all zone-programmable functions appears in section 8.
EDITING A PRESET
To edit an existing preset, enter Edit Mode and select the desired edit screen with the appropriate FUNCTION switch. As an example, we will use the first screen of function group 4 (ZONE).In this example of an Edit Mode display, there are four
parameters shown. The current value of each parameter appears below the parameter name, and may be changed with the corresponding control slider (while in Edit Mode, any MIDI control functions assigned to a control slider are disabled). The zone digit is present because these functions are zone-programmable (when editing a zone-programmable function, be sure that the correct number is displayed or the wrong zone may be inadvertently changed).
There is a Star on the third parameter of this screen. The Star is used in several functions to indicate that there is an alternate screen which can be accessed by pressing the Star switch. The alternate screen contains additional parameters that are related to the main screen but which are not always used. To get back to the main screen press the Star switch again. While in Edit Mode, any MIDI control functions assigned to the Star switch are disabled.
The Alpha switch is also used in Edit Mode, usually to initiate special operations like memory load or save. Its function will be designated on the screen where it is used. While in Edit Mode, any MIDI control functions assigned to the Alpha switch are disabled.
CREATING NEW PRESETS
Creating an entirely new preset requires three steps: configure the zones, program each zone, and program any desired miscellaneous Preset-programmable functions. The specific details of zone functions and miscellaneous preset functions is covered in reference sections 7 and 8. After learning how to create basic presets in this section, scan sections 7 and 8 to become familiar with the many powerful functions available, and consult specific explanations as needed. Before any presets are created, all devices used in the MIDI system must be designated by a five-character name and entered into the SL-2001's device list. The MIDI port and channel associated with each device is also entered.
DEVICE INSTALLATION
The DEVICES screen is used to enter the name and description of all MIDI devices in the system. This information should be entered into the SL-2001 before any new presets are created. For every device in the system, the SL-2001 must know the port to which it has been connected and the MIDI channel on which the device is transmitting or receiving. SL-2001 presets are then easily created by referring to the device name only; the port and channel are implied by the name and need not be displayed.
INPUTDEVICES
Keyboards, MIDI guitars, drums, or other controllers are input devices. As an example we will install a MIDI keyboard which has been plugged into input A of the SL-2001. We will assume that the keyboard is set to transmit on MIDI channel number one. While in Edit Mode (red light on EDIT switch is on) access the DEVICES screen by pressing function switch 2
1.Using Control Slider 2, set the Port parameter to IN A. This means that the keyboard we are installing is physically connected to MIDI IN A ofthe SL-2001.
2.Adjust Control Slider 3 until the Channel parameter is on 1. This signifies that the keyboard has been set to transmit information to the SL-2001 on MIDI channel 1.
3.Once the Port and Channel are properly set, the device name can be entered by pressing the Star switch.
