1. USB Port: Use a standard USB cable to connect this USB port to your computer. The
computer's USB port provides ample power to MPD232. If you connect it to a USB hub,
make sure it is a powered hub. This connection is also used to send and receive MIDI
data to and from your computer.
You can also power MPD232 by connecting this USB port to a power outlet using a
standard USB charger (sold separately). If you do this, set any relevant controls to send
their MIDI messages out of the MIDI Out. Any controls set to transmit only over the USB
Port will not be sent to a device connected to the MIDI Out.
When using MPD232 with external MIDI equipment:
•
If an external device is connected to the MIDI Out, your computer can send MIDI
messages out along this path: Computer  MPD232  External Device.
•
If an external device is connected to the MIDI In, the external device sends MIDI
messages in along this path: External Device  MPD232  Computer. MIDI
messages can then be sent to an external device via the MIDI Out, but they must
pass through the computer first.
2. Power Input: Connect this power input to a power outlet using an optional power adapter
(6V DC, 1A, center-positive, sold separately). Alternatively, if you want to use MPD232 to
control an external MIDI device and without a computer connection, you can connect
MPD232's USB Port to a power outlet using a standard USB charger (sold separately).
3. Power Button: Press this button to power MPD232 on or off.
