Introduction
1. Features of the UM-4
The UM-4 is a USB MIDI interface which uses USB as its connection to your computer.
■ Four MIDI Ports
Four MIDI ports (each with MIDI IN/OUT) can be controlled independently.
■ Four MIDI Indicators
Convenient MIDI indicators for both input and output allow you to verify MIDI data
activity.
■
Easy Connection to Your Computer with a Single USB Cable
Connections to your computer can be made even when the power is turned on. No special
settings are required.
■ High-Speed Data Transmission via USB
High-speed USB connection provides excellent response even with simultaneous playback
on multiple channels.
■ A Maximum of Four Units can be Used Simultaneously
If a USB hub* is used, you can use up to four UM-4 units simultaneously.
* A device used for adding additional USB connectors.
■ EIA-1U Half-Rack Size
A separately sold rack mount adaptor (Roland RAD-50) can be used to rack mount the UM-4.
■ Power Supply Not Required
Power is supplied from the computer itself, so a separate power supply is not required.
What is USB?
USB stands for Universal Serial Bus, which is a new interface for connecting various
types of peripheral device to computers.
A single USB cable can be used to connect multiple peripheral devices, and data
transmission speed is much faster than the serial port used on previous computers.
In addition, peripheral devices can be connected or disconnected without turning off
the power, and the computer will automatically detect the device which was
connected. (For some peripherals, you may need to make settings or perform other
