Connecting To Your Computer/Midi Keyboard; Connecting To A Computer Via The Usb Connector - Roland SC-8820 Owner's Manual

Connecting to Your Computer/MIDI Keyboard

Connecting to a Computer
There are three ways to connect the SC-8820 to your computer; using the USB con-
nectors, the MIDI connectors or the Serial connector. You can use up to 32 parts
if you use the USB connectors or the Serial connectors, and up to 16 parts if you use
the MIDI connectors. And if you use the MIDI connectors, you will need to obtain a
computer interface board (adaptor) that has MIDI connectors (such as the Roland
Super MPU II, etc.). If you use the USB connectors or the Serial connectors, you can
use a special cable to connect the SC-8820 directly with the computer, but your soft-
ware must be able to correspond to the USB port or the Serial port. (Refer to the How
MIDI Messages Are Exchanged with a Computer p.14)

Connecting to a Computer via the USB Connector

USB stands for Universal Serial Bus, and is a new interface used for connecting var-
ious peripherals to a computer.
USB allows you to use a single USB cable to connect numerous peripheral devices,
and allows data to be transferred faster than previous serial ports.
Also, peripheral devices can be connected or disconnected while the power is still
turned on, and the computer will detect this automatically. (For some peripherals,
settings or other operations may be required.)
The SC-8820 is supplied with power from its connected AC adaptor, but it also sup-
ports bus power supply. Power can be supplied simply by connecting a USB cable,
so that an AC adaptor need not be connected. Before disconnecting the AC adaptor,
please turn the power switch OFF.
* For the most stable operation, we recommend that you use it with the AC adaptor connected.

To prevent malfunction
and/or damage to speakers
or other devices, always
turn down the volume, and
turn off the power on all
devices before making any
connections.
When connecting your
computer to the SC-8820
via a USB cable, it is not
necessary to turn off the
power of your computer.
Depending on the power
supply conditions of your
computer or USB hub, the
SC-8820 may not operate
on bus power supply. If
this is the case, please use it
with the AC adaptor
connected.
