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.
