Memory Card - Studiologic SL-2001 User Manual

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 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:
