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. There is a USB Mini B socket for supplying power
and new for the mk3 there is a recessed push switch for selecting the operating mode and a three
colour LED to replace the original green one.
The MIDI USB Host is powered by a USB type regulated 5V mains adaptor (supplied), and can supply
up to 910mA of buss power to the attached USB device.
The mk3 has three operating modes:
Standard (LED Green)
– MIDI received at the MIDI In socket is sent to the USB device and data from
the USB device is sent to the MIDI Out socket.
Merge 1 (LED Amber)
– MIDI IN does not go to USB device but instead is merged with data coming
from the USB device which is sent to the MIDI Out socket.
Merge 2 (LED Red)
– MIDI IN data is sent to the USB device & is also merged with data from the USB
device which is sent to MIDI Out socket.
