Connecting MIDI Devices and Computers
MIDI stands for Musical Instrument Digital Interface, which is a world-wide standard communication
interface that enables electronic musical instruments and computers (of all brands) to communicate with
each other. MIDI sends note and other communication between devices. This exchange of information
makes it possible to create a system of MIDI instruments and devices that offer greater versatility and
control than is available with isolated instruments. Whether you interface with computers, sequencers,
expanders or other controllers, your musical horizons will be greatly enhanced.
MIDI USB connection
The USB connector allows you to connect the module directly to your computer. It can be connected
without driver installation under the Windows & MAC OSX environment. The module will be
recognized to receive and transmit MIDI messages through a single USB cable, USB is used only
for MIDI messages (MIDI via USB). The SD550 module will appear as “SD550” in the USB device
options of your software.
NOTE:
When the USB is connected to a computer, all MIDI messages will be received and transmitted
via USB.
