    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 pre- set, press any of the eight PRESET switches. To change to a different bank, press the left or right arrow switches ( <...
  • Page 3 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 sec- ond, third, and fourth modules respectively.

  • Page 4: Basic Information

    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 of MIDI functions.

  • Page 5: 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.

  • Page 8: Device Names

    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- •...

  • Page 10: Operation

    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 perform- ing MIDI data processing (although certain functions are inhibited which would interfere wdth the programming procedure).

  • Page 11: Edit Mode

    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.

  • Page 12: Function Types

    ZONE-PROGRAMMABLE (function groups 4 through 8): These functions contain parameters that are different for each zone (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.

  • Page 13: Editing A Preset

    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.

  • Page 14: Input Devices

    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.

  • Page 15: Output Devices

    To install a second device (for example, another keyboard on MIDI IN B) adjust the port and channel values as necessary, press the Star switch, and enter the name of the new keyboard. The SL-2001 local keyboard is designated by the device name "2001";...

  • Page 16: Zone Configuration

    ZONE CONFIGURATION The first step in creating an entirely new SL-2001 preset is the configuration of the zones. Each zone functions as a link between the keyboard and an output device (a sound module). For each zone that will be used in the preset, the input and output must be assigned to the desired devices.
  • Page 17 After assigning the zone inputs and outputs, the zone must be enabled with the front-panel ZONE switch. The green light indicates that the zone is active. Note that at least one zone must be active in every SL-2001 preset, otherwise MIDI data can...

  • Page 18: Zone Bypass

    The next step is to program the many zone functions which make the SL-2001 a very powerful master keyboard. The Program, Volume, and Transpose functions are fundamental to every SL-2001 preset. They permit initialization of the program number, volume level, and transpose interval for each sound module used in the preset.
  • Page 19 See the section below entitled Storing Presets. MISCELLANEOUS PRESET FUNCTIONS The final step in creating a new SL-2001 preset is to program any miscellaneous Preset-programmable functions that are need- ed. Refer to section 7 for complete information on these functions: AUX PROG: Sends program changes to effects units, mixers, or other devices.

    ZONE switch of the destination. After completing the copy operation, the SL-2001 will return to Edit Mode. A store operation may be aborted at any time by pressing the STORE switch. The SL-2001 will revert back to Edit Mode or Perform Mode.

  • Page 21: Utility Functions

    MIDI ACTIVITY This screen is used to indicate the presence of MIDI messages on the MIDI input and output ports of the SL-2001. As a mes- sage enters or leaves a port, the letter A though D will flash briefly to indicate the activity. In the example above, a message has entered MIDI IN D and two other messages have been sent on MIDI OUT A and B.

  • Page 22: Memory Transfer

    The SL-2001 uses a dynamic memory allocation scheme, which means that the storage space for a preset is dependent on the number of functions that are active in that preset. It is possible (but very unlikely) that the memory space will become full before all presets have been programmed.

  • Page 23: Global Functions

    DEVICES The Devices screen is used to enter the name and description of all MIDI devices in the system under control of the SL-2001. This information should be entered into the SL-2001 before any new presets are created. A detailed explanation of the device installation procedure appears in Section 4.

  • Page 24: Preset Functions

    Control Slider 1 is used to enable SL-2001 preset changes via MIDI program change commands. Slider 3 is used to select the device from which the SL-2001 will accept program change commands. Program changes from all input devices will be accepted by selecting All on Slider 3.
  • Page 25 Upon entering this screen, a flashing character will indicate the current position of the cursor. Use Control Slider 1 to select the desired character for this position, or press the appropriate key on the SL-2001 keyboard.. To change the position of the cursor, use the left and right arrow switches (<...

  • Page 26: Switch Modes

    Each switch (A, B, C, Star, and Alpha) may be set for either a momentary response or toggle mode. In Perform Mode the cur- rent state of all switches is displayed on the SL-2001 front panel. Switches A, B, and C appear in the text display; the Star and Alpha switches each have LED indicators.

  • Page 27: Zone Functions

    ZONE FUNCTIONS The zone functions contain a separate set of parameters for each zone. This means that every SL-2001 preset has eight sep- arate storage areas to save the parameters for each zone. Whenever a zone-programmable function is edited, the zone digit(s) will appear after the Preset digits.
  • Page 28 D. The note range parameters do not apply to a bypassed zone and are not displayed. The only other function avail- able is ZONECTL. ZONE CTL The eight ZONE switches on the SL-2001 front panel may be used at any time to activate or disable a zone.
  • Page 29 The delay function is not available for zones that are bypassed, and the parameter values are not displayed. PROGRAM The most fundamental parameter in a MIDI system is the program number for each device. The PROGRAM screen is used to specify the program number issued to each device at the instant a SL-2001 preset is selected.
  • Page 30 The top line of the display shows the output devices to which zones one through four are assigned. The bottom line indi- cates the number of the program that will be selected on each device as a SL-2001 preset is entered (the letter P distinguish- es this screen from the VOLUME, TRANSPOSE, and AUX PROG screens).
  • Page 31 VELOCITY The Velocity edit screen contains all parameters related to the velocity value of a MIDI note message. Control Slider 1 is used to set the Velocity-Switch function. This function filters out MIDI note messages based on their veloc- ity value. When set to All, note messages will pass through the zone regardless of their velocity value. Other settings will only pass note messages that are above or below a certain velocity value (the range of velocity values for a note-on message is 1 to 127).
  • Page 32 The graphs show the relationship between the velocity value received by the zone input and the velocity value sent to the SL-2001 output. The Linear curve does not translate the velocity value; the output value is identical to the input. The Shelf curve has the effect of compressing the middle velocity range so that the output values tend towards the center of the range (64).
  • Page 33 There are two ways to program the Key Map function. Control Slider 1 may be used to select a note, and Control Slider 2 determines if the note is On (passed) or Off (filtered). Alternately, the key map may be directly programmed from the key- board.

  • Page 34: Volume Control

    As in the PROGRAM screen, the top line displays the names of the devices (or ports) controlled by zones one through four. The bottom line shows the value of the MIDI volume control message that will be issued as the SL-2001 preset is selected.
  • Page 35 By using the SL-2001 instead, the noise and reliability problems of a mechanical volume pedal are eliminated. The diagram below illustrates the volume control function in a preset using three zones. Three zones are active in this example. The initial volumes have been programmed on the VOLUME screen to achieve the desired relative mix.
  • Page 36 This means that playing one note on the MIDI keyboard could produce a chord on a single sound module (however it is more efficient to use the SL-2001 Chord function than to use multiple zones).
  • Page 37 The final group of SL-2001 edit screens contain all functions relating to the processing of MIDI control change messages by the zone. If a zone is associated with the SL-2001 keyboard, all control change messages will originate from the SL-2001 local controls (wheels, switches, sliders, etc.).
  • Page 38 SL-2001 keyboard Any control message from any source can be either passed directly to the SL-2001 MIDI outputs, converted to any other con- troller, or blocked completely. Messages may also be scaled to adjust the depth of the control effect using Control Slider 2.
  • Page 39 MIDIcc The MIDI cc screen applies to continuous controller messages from external instruments. Operation of this screen is nearly identical to the CONTROLS screen. Control Slider 1 is used to select among the MIDI con- tinuous controller messages: cc #. Definition____cc * Pitch Channel Pressure 10...
  • Page 40 MIDIsw The MIDI sw screen applies to switch messages from external instruments. Use Control Slider 1 to select a MIDI switch message type: sw # Definition_________sw # Sustain (damper) Portamento Sostenuto Soft Pedal Hold 2 Gen'l Purpose #\ If a controller type does not have a standard name, it will appear on Control Slider 1 as csw plus its number. Use Control Slider 2 to adjust the depth.
  • Page 41 SL-2001 UPDATE SOFTWARE VERSION 2.1 Version 2.1 includes the changes listed below: - MIDI Clock - Start, Stop - FUNCTION FOR SEQUENCERS, DRUMS MACHINES, COMPUTERS ecc.. - Direct Program Change - FUNCTION FOR FAST PROGRAM CHANGES COMMAND. - Port/channel - UTILITY FOR CHECK THE SETTING OF DEVICE INSTALLATION (FAST MONITOR).
  • Page 42 Each switch (A, B, C, Star and Alpha) may be set for either a momentary response or toggle mode. In Perform Mode the cur- rent state of all switches is displayed on the SL-2001 front panel. Switches A, B, and C appear in the text display; the Star and Alpha switches each have LED indicators.
  • Page 43 A direct program change feature is available which allows faster access to any program number. PRESET switches 1 through 8 and the left/right arrow switches are used as a keypad to enter the desired number (the left/right arrow switches represent the numerals 9 and 0).
  • Page 44 ZONE The SL-2001 operates by routing MIDI data from the master (or external) keyboards to the sound modules via eight MIDI pro- cessors or "zones". To establish these links, the zones must be configured to receive the information from the performance device and send it the output devices.
  • Page 45 PRESET-CHANGE ENABLE If the SL-2001 presets are to be selected via MIDI program change commands, it is necessary to specify the source of these commands. Control Slider 1 is used to enable SL-2001 preset changes via MIDI program change commands, Slider 3 is used to select the device from which the SL-2001 will accept program change commands.
