1.3 System Requirements
Hardware
The 12 Step is a class-compliant USB MIDI device —!it will work with any hardware or software that
supports MIDI.
The 12 Step hardware itself will work on any operating system (assuming there is native USB and
MIDI support). It can even work with computers that may not be able to run the editors but still
support USB 2.0 and MIDI (editing presets will have to be done on another computer in this case).
Software
The 12 Step editor has more specific requirements than the 12 Step hardware.
Mac
Mac OS 10.6 or later
•
Intel Core 2 Duo 2.0 GHz or greater
•
Roughly 100 MB free hard disk space
•
A 12 Step foot controller
•
Before You Begin 9
Windows
Windows 7, or Windows 8 (we do not support Windows XP or Windows Vista)
•
Intel Core 2 processor or greater
•
Roughly 100 MB free hard disk space

2.0 Getting Started
This section covers information that will help get started with the 12 Step. We will introduce the 12 Step
hardware, the MIDI Expander hardware, how to connect 12 Step to the world, and basic operation of
the pedal.
2.1 12 Step Hardware
The 12 Step hardware!!!
2.1.1 Overview
(1) Keys
Keys are where the action happens. Step on these to make the 12 Step output notes and other
MIDI messages.
Each key has an accompanying red LED (located at the north or northeast corner of the key) for
visual feedback.
(2) Select Button
The select key is a special, multi-function key used to change presets, shift octaves, and switch
between note modes.
(3) Display
Used to show the currently loaded preset’s display name.
Getting Started 12
(4) USB Ports
Used to connect the 12 Step to the MIDI world. Connect a KMI MIDI Expander using the Expand
port (USB-mini) or connect to a computer/tablet via the main USB port (the big one).
(5) Pedal Input
Used to connect an expression pedal to the 12 Step. All input should use a 3.5mm (1/8”) TRS cable
to work properly. Most expression pedals have a stereo 1/4” jack —!an expression pedal adapter
(female 1/4” TRS to male 3.5mm TRS) is included with every 12 Step.
2.1.2 Specs
The “deets”:
Dimensions & Weight
Dimensions: 4.1” x 17.7” x 0.94” (105mm x 450mm x 24mm)
•
Weight: 1.3 lbs (0.59 kg) (approximately)
•
Power Draw / Requirements
The 12 Step can be powered via the main USB port or the Expander port. It should never be
powered from both ports at the same time — this may result in damage to the hardware.
Voltage: +5V
Power draw: 150mA (approximate measurements)
Note: There are no user serviceable parts inside the 12 Step. Attempts to open the enclosure will void the
warranty.

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.
Getting Started 14
(6) Expand Port
Used to connect the MIDI Expander to the 12 Step. Just use a mini USB cable to connect the 12
Step’s Expand port to the Expander’s EXPAND port.
Note: Only KMI MIDI controllers should be connected to the EXPAND port —!other USB MIDI controllers
and USB hubs will not work properly.

2.3 Connecting 12 Step
The 12 Step can talk to computers and tablets via USB, and MIDI hardware via MIDI cables (KMI MIDI
Expander required). Both methods can be used independently or simultaneously.
2.3.1 To A Computer
Connecting the 12 Step to a computer requires three things: a 12 Step, a computer, and a USB A to
USB B cable (the “classic” USB cable). Simply plug the 12 Step’s main USB port into a USB 2.0 (or
greater) port on the computer. The 12 Step will receive power from the computer.
Note: The 12 Step can also be used with a USB hub connected to a computer. It is highly recommended
to use a powered USB hub, not a bus-powered hub. Bus-powered hubs may not be able to provide enough
power to the 12 Step to function properly.

Getting Started 16
Connecting the 12 Step to an iPad is very similar to connecting to a computer, the only difference is
that one more part is needed.
An Apple Lightning to USB Camera Adapter (for iPads with Lightning connectors) or an Apple iPad
Camera Connection Kit (for iPads with the older 30-pin connectors) is required to connect the 12
Step to an iPad via USB.
Plug the adapter into the iPad, plug the 12 Step’s main USB port into the adapter with a USB A to B
cable, and everything is ready to go.
Note: Some iPad models may not be able to power the 12 Step without some help — the 12 Step may
have to be powered externally with a USB power supply (5V, 500mA). Just plug the 12 Step’s mini-USB port
(the Expand port) into the power supply, then plug the power supply into a power outlet.

A KMI MIDI Expander is required to connect to MIDI hardware via MIDI cables.
1. Connect the 12 Step’s EXPAND port to the EXPAND port on the Expander using a USB A to
mini-B cable.
2. Connect the Expander’s POWER port to a USB power supply (included with Expander
package) using a USB A to B cable.
3. Plug the power supply into a power outlet —!the 12 Step and Expander should power up.
4. Use a MIDI cable to connect the Expander’s MIDI OUT to the MIDI IN on the external
hardware. Use a second cable to connect the Expander’s MIDI IN to the MIDI OUT on the
hardware if input to the 12 Step is desired.

Most standard expression pedals can be directly connected to the 12 Step and used to send MIDI
data.
1. Set up the 12 Step in whatever configuration is desired (computer/tablet, Expander, or both).
2. If the expression pedal has a 1/4” TRS connector, plug it into a 1/4” female to 1/8” male
adapter (one is provided with each 12 Step).
3. Plug the expression pedal into the 12 Step’s Express port, and setup is complete!
Note: Volume pedals do not work with the 12 Step or any KMI controller with expression pedal input.
Only expression pedals are compatible. For more info, please see this FAQ.
Getting Started 20
2.4 Start Playing
Here’s a quick overview of how to start interacting with the 12 Step!
2.4.1 Initial State
Upon first powering up, the 12 Step will be on the default “Chromatic Scale” preset (the display will
read “CHrO”). This preset should behave like a normal keyboard — each key plays a note when
pressed and stops when released.
Note: The initial preset may change if any editing has been done, but the factory state of the 12 Step
should load with the Chromatic Scale preset when first powered on.
2.4.2 Playing Notes
To play notes on the 12 Step, simply step on one of the keys (just not the special “Select” key).
Typically, a note (or notes) will turn on when the key is pressed and turn off when the key is
released —!this behavior can be changed using the various Note Modes.
2.4.3 Changing Presets
Preset changing is handled using the 12 Step’s Select key. Simply do the following:
1. Press and hold the Select key until all of the 12 Step’s red LEDs begin to flash, then release the
key. The 12 Step is now in what is referred to as “Select Mode”.
2. Step on one of the numbered keys to switch to the preset associated with that particular
number. After selecting a preset the 12 Step will automatically load it and exit preset selection
mode.
3. Start playing!
Advanced Info
The 12 Step is able to hold up to 64 presets, but how exactly are they accessed? Like so:
1. Enter Select Mode by holding down the 12 Step’s Select key.
2. Press the 12 Step’s Enter key.
3. Use the -Oct/-10 and +Oct/+10 keys (the keys to the immediate left and right of the Select
key) to select a “decade” (10s, 20s, 30s, 40s, etc) —!the current decade will be shown on the
12 Step’s display.
4. Step on one of the numbered keys to fill in the final digit of the decade (e.g. stepping on
key 7 in the 30s decade will load preset 37). The preset will load and be ready to go.
Note: The 12 Step will remember which decade it’s in if Select Mode is entered again. Scrolling
through the decades every time is not necessary.
Getting Started 21
2.4.4 Changing Octaves
It is possible to transpose 12 Step presets up and down by an octave directly from the board.
Similar to changing presets, octave shifting makes use of the Select button. Do the following:
1. Press and hold the Select key until all of the 12 Step’s red LEDs begin to flash, then release the
key. This is referred to as “Select Mode”.
2. Step on either the key labelled “-Oct” (to shift down an octave) or “+Oct” (to shift up an octave).
3. Start playing! After stepping on one of the octave +/- keys the 12 Step will automatically shift
and exit Select Mode.
