2.2 MIDI Expander Hardware
The KMI MIDI Expander is an optional accessory that allows the 12 Step to connect to external MIDI
hardware via MIDI cables.
2.2.1 Overview
(1) MIDI In
MIDI input to the Expander. Incoming MIDI will be passed through the 12 Step and up the USB
connection to a connected computer or tablet —
similar to a MIDI interface. MIDI sent into the
Expander’s input can also be used to control the 12 Step LEDs, display, and presets.
(2) MIDI Out
MIDI output from the Expander. MIDI from the 12 Step (and a connected computer) can be sent
out of this to external MIDI hardware.
(3) Input LED Indicator
Flashes when MIDI is received at the MIDI In port.
(4) Output LED Indicator
Flashes when MIDI is sent out of the MIDI Out port.
(5) Power Port
Used to power the MIDI Expander and an attached 12 Step. Just plug a USB power supply (one is
provided with the Expander package) into an outlet, then connect the power supply to the POWER
port on the Expander with a USB A to B cable (also provided with the Expander).
Note
: If nothing is plugged into the EXPAND port when powered, the Expander’s Input and Output LED
Indicators will light up. This is just to indicate that the Expander is being powered —
no MIDI is actually being
output or received. Once a KMI controller is connected to the EXPAND port they will turn off and behave
normally.
