Description
The MIDI USB Host has a USB Host port (USB A socket), a MIDI IN and a MIDI OUT (both 5 pin DIN).
MIDI data received at the MIDI IN socket will be sent to the USB device. MIDI data received from the
USB device will be sent to the MIDI OUT socket.
The MIDI USB Host is powered by a regulated 5V mains adaptor (supplied), and can supply up to
500mA of buss power to the attached USB device.
Connecting
It is recommended that you attach your USB device to the MIDI USB Host before applying power. Then
plug-in and power the power adaptor. The active LED should be lit up. If you apply power with nothing
plugged into the MIDI USB Host, the Active LED will flash steadily; this is to indicate that it is waiting for
a suitable device to be attached. If it is still flashing when you have attached your device, then it is
possible that your device is not class compliant, however you could try turning off the power and start
again.
Some USB MIDI devices have two modes of operation and can be set to operate in Class Compliant
mode even if this is not the default. The Class Compliant mode might be called “generic driver”, the
other mode may be called something like “advanced driver”. Consult the device manual to see if the
mode can be set for Class Compliant.
If you unplug then re-plug the USB cable while it is powered the device might reconnect, but it is not
certain.
Power
It is essential to use only the supplied 5V regulated power adaptor. Applying a voltage higher than 5V
to the MIDI USB Host will probably not damage the MIDI USB Host itself, but it could damage any
