icate an entire zone just to send program change commands. The SL-2001 has the ability to send simple MIDI program
change commands to eight auxiliary devices. Selecting the Aux option (csl 2) identifies the MIDI device as an auxiliary unit
which will receive MIDI program change commands independently of the zones (although a zone may still be assigned to
an Aux device if desired). The eight devices designated as auxiliary units will appear on the AUX PROG screen, where the
desired program change values may be entered (see section 7 for further information).
The Format parameter refers to the arrangement of presets on the MIDI device being installed. There are four preset formats
in common use: MIDI, MIDI+1, Bank, and Alpha.
MIDI: Presets on the instrument are numbered starting with program 0 (zero) and increase by single steps. Example: 0,1,2,
3, 4, 5, 6,7,8,9,10,11,12, etc.
MIDI+1: Presets on the instrument are numbered starting with program 1 and increase by single steps. Example: 1, 2, 3, 4,
5,6, 7,8,9,10,11,12, etc.
Bank: Presets are arranged in banks, with eight presets per bank. The first digit of the preset specifies the bank, and the sec-
ond digit specifies the preset within the bank (this is the format used on the SL-2001). Example: 11,12,13,14,15,16,17,18,
21, 22, etc.
Alpha: Presets are designated by a letter plus a number from one to eight. Example: Al, A2, A3, A4, A5, A6, A7, A8, Bl, B2,
etc.
By setting the Format parameter to match the instrument being installed, the SL-2001 will be able to display program change
settings on the edit screens in the proper format. This greatly simplifies programming of presets; if you know that a particu-
lar string preset on a synthesizer is in bank 2 preset number 1, you do not need to know that this is actually equivalent to
MIDI program change command 8.
After the device name has been entered and the program and format parameters have been set, press the Star switch to return
to the main screen. The new device will now be displayed with the port and channel as programmed.
Repeat the installation procedure for all devices in the system. If you have a multi-timbral sound module, each channel of
the instrument must be installed as a separate device. As an example, if sound module XYZ can play two sounds at once,
install device XYZ1 and XYZ2 into the SL-2001 device list.
Once all devices have been installed, it is possible to review the list of devices at any time. The first three control sliders are
all active on the main screen. Moving Control Slider 1 scrolls through the list of all device names. The port and channel will
change to match the values chosen when the device was installed. Moving the port (or channel) slider will likewise cause
the device name to change accordingly.
NOTE: To change the port and channel for a device after it has been installed, it is necessary' to delete the device (using the
Alpha switch} and re-install it. Clanging the name, Prg parameter or Format parameter/or a device dues not require dele-
tion. Select the device on the main screen, then press the Star switch to access the alternate screen for editing.
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. Enter Edit Mode and press FUNCTION switch 4 to access the ZONE screen.
The zone digit will display the number of the zone to be edited, and may be changed with the left and right arrow switches.
In normal operation, a zone receives MIDI data on only one specific channel, processes the data, and sends the data to a SL-
2001 output on a single MIDI channel. The source and destination for the zone are selected by choosing a device name from
the SL-2001 device list. The actual SL-2001 port and channel number need not be specified, as they are implied by the device
name,
Multiple zones can be assigned in any combination to the SL-2001 keyboard or external keyboards. Up to eight sounds may
be controlled simultaneously, each with fully independent key range, dynamics, transpose, etc.
