Some more sophisticated audio effects units are able to respond to MIDI control change commands (for example, the wet/dry
mix on a reverb unit). In this case, we would use a zone so that the reverb parameter can be controlled in real time using one
of the SL-2001 local controllers or a MIDI control (see section 8).
To select program numbers for devices assigned to zones five through eight, press the right arrow switch (>); the zone digits
will display 58. If more than one zone is assigned to the same output device, the program number may only be entered for
the first zone connected to the device; the program numbers will be blank under the duplicate names. This prevents con-
flicting program numbers from being sent to one device.
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.
The ZONE function is used to configure the eight zones as needed for the preset. The zone configuration is the most basic
of all SL-2001 functions and should be edited or checked before any other parameters are modified.
After selecting the ZONE edit screen, the left and right arrow switches (<>) can be used to quickly scan the input and output
assignments for each zone.
Note that the zone digit is displayed to indicate the number of the zone currently being edited. Control Slider 1 is used to
select the zone input device, and Control Slider 2 is used to select the output device. In the example screen, Kybd2 is now
able to send MIDI information to Mod#3 via zone number one. All of the MIDI devices installed during the Device Installation
will appear on Control Slider 1 or 2. Selecting devices from this list is equivalent to programming the zone input and output
for a specific MIDI port and channel (implicit in the name). If for some reason you need to know the actual port and chan-
nel assignments for the zone, you can either check the settings on the device installation screens, or you can simply press the
Alpha switch; the device names will temporarily change to show the actual port and channel assignments. MIDI units instal-
led as Auxiliary devices may be selected for a zone output, although in most cases they will be accessed only on the AUX
PROG screen.
A zone may be programmed to operate only in a specific region of the master or external keyboard. Use Control Slider 3 to
set the lowest desiderd note, and Control Slider 4 to select the highest note desired. This range may also be programmed by
selecting the notes on the keyboard for that zone. Press the Star switch to access the alternate screen. Press the two keys that
correspond to the highest and the lowest notes desired for the zone. You must play these notes on the instrument specified
on the screen. After the second note is pressed, the display will automatically revert to the main ZONE screen with the new
settings as programmed.
In some applications it may be desiderable to pass MIDI information on all 16 channels directly from one MIDI input to a
MIDI output. If a zone is bypassed in this manner, none of the MIDI processing functions are available, the zone functions
only to direct the data to a specific output. To bypass a zone, use Control Slider 1 to select an input port. Control Slider 2 will
now display only the four output ports A through D. The note range parameters do not apply to a bypassed zone and are not
displayed. The only other function available is ZONE CTL.

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. Program changes from all input devices will be accep-
ted by selecting All on Slider 3.
The Conditional Preset Change function allows the SL-2001 preset change to be delayed under any of the following condi-
tions:
1) there are currently notes being held on the keyboard;
2) the sustain pedal is currently pressed;
3) one or more zones are using the delay function, and there are notes or other events which have not yet appeared on the
output of the zone(s).
The Conditional Preset Change function applies to the front-panel PRESET switches as well as a preset-change command
from any source (MIDI IN A through D, Inc/Dec). During the time that the preset change is delayed, the Preset digits will
flash until the conditions are met. If desired, the conditional program change may be forced by using the All-Notes-Off func-
tion (press the Edit and Store switches simultaneously). If the preset change is waiting for delayed Zone events, turning off
the zone(s) will force the preset change.
