2.2 MIDI Expander Hardware

The KMI MIDI Expander is an optional accessory that allows the SoftStep 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 SoftStep 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 SoftStep LEDs, display, and presets.

(2) MIDI Out

MIDI output from the Expander. MIDI from the SoftStep (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 SoftStep. 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.
