MIDIPLUS suggests that you connect directly to your computer built
in USB ports.
1.3 Installation
AKM320 do not need other driver to work with a computer, only
needs the USB Audio Driver built in the system.
The first time you connect AKM320 to your computer, it will
automatically install the general USB-Audio Driver. After installation,
the system will tell you the "new hardware" is ready to use.
1.3.1 Play with your Application Software
Generally, in PC or Mac, most MIDI software will have a MIDI port
configuration or settings, sometimes it called “MIDI Devices” or
“MIDI Setup”. You can choose and enable your MIDI input and
output devices in it.
If the AKM320 driver is properly installed, and there is no other MIDI
device connected, the MIDI In port of AKM320 In-1 (or “Port 1” on
the Mac) will be selected as the first midi input, while the MIDI Out
port of AKM320 Out-1 (or Port 1) will be selected as the first midi
output.
If the MIDI software runs, and the MIDI-In and Out port in AKM320
are selected, the MIDI message will be received when playing the
AKM320 keyboard.
1.4 Power supply
Connect an USB cable from your computer to the AKM320. The unit
will be powered by the computer USB, no additional power adaptor
