able from your dealer, or any DC control voltage source may be used. The input voltage range is 0 to 5 volts DC, which cor-
responds 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 batteries.
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.

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 equip-
ment.
The SL-2001 will command at least eight sound modules (or keyboard synthesizers) simultaneously and at least eight auxil-
iary MIDI devices (audio effects units, mixers, lighting controllers, etc). More than thirty-two MIDI devices may be connect-
ed and selectively accessed under preset control. The four MIDI outputs are completely independent, which means that
sixty-four MIDI channels are available.
BACK PANEL CONNECTIONS
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 informa-
tion 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 be programmed for a wide range of MIDI 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 play-
ers will want to use three double footswitches simultaneously, in order to effect quick sound changes while playing the key-
board.
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-
