1.2 COnneCtinG 12 Step2
12 Step2 features new options for connecting to your hardware. New to the 12 Step2 is a USB-C
connection for sending USB MIDI, as well as TRS MIDI Out and CV Outputs for connecting to MIDI
hardware and analog synthesizers.
USb Midi
Connect the 12 Step2 to a computer or tablet with the included USB A-to-C cable. 12 Step2 will receive
power from the computer or tablet.
Note: 12 Step2 can be used with a USB hub connected to a computer or tablet. 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 Step2 to function properly.
Use the USB-C jack to power the 12 Step2 when not using a computer.
trS Midi OUt
12 Step2
Connect 12 Step2 to MIDI hardware via the TRS MIDI Out jack. Use a TRS-MIDI Adapter (Type A) to
connect to 5 pin MIDI hardware.
Cv OUt 1/2
12 Step2 can control modular and analog synthesizers with Control Voltage signals. Use the Editor
software to select Pitch, Gate or a Control Source to be sent to the CV Outs.
The CV Out is a TRS jack. CV1 is sent on the tip and CV2 is sent on the ring.
The default setting outputs Gate (CV Out 1) and Pitch (CV Out 2).
expreSSiOn pedal inpUt
Plug an expression pedal into the 12 Step2 and use it as a MIDI control source. Use a 1/4” to 1/8” TRS
adapter cable to connect the 12 Step2 to the expression pedal. The range of the expression pedal can be
calibrated with the 12 Step Editor software.
Note: Volume pedals do not work with the 12 Step or any KMI controller with expression pedal input. Only
expression pedals are compatible.
kMi Step adapter kit (SOld Separately)
The KMI Step Adapter Kit contains all the adapters you need to connect your 12Step2 to external devices.
The Kit includes a TRS MIDI Out adapter, a CV 1/2 breakout adapter, and a 1/4” to 1/8”TRS expression
pedal adapter.

1.3 USinG 12 Step2
playinG nOteS and ChOrdS
To play notes on the 12 Step2, 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.
ChanGinG preSetS
The 12 Step2 hardware can store up to 64 presets.
To select a preset, press and hold the “Select” key. The 12 Step2 will begin to ash, indicating it is in “Select
Mode”. Press one of the numbered keys to ll in the one’s digit, select the corresponding preset and exit
“Select Mode”.
By default, the decade of the preset you are selecting will be the same as the currently loaded preset. To
change the decade, press “Enter” while in Select Mode, then press the “-10” or “+10” keys to the left and
right of “Select” to scroll through the decades.
ChanGinG OCtaveS
You can transpose the entire 12 Step2 keyboard up and down by octaves. Similar to changing presets,
Octave shifting makes use of the Select button.
To change octaves rst press and hold the “Select” key. The 12 Step2 will begin to ash, indicating it is in
“Select Mode”. Next press the “-Oct” key (Eb) to shift down an octave, or the “+Oct” key (F#) to shift up an
octave and exit “Select Mode”. You will need to press/hold “Select” again to transpose another octave.

12 Step2
1.4 external COntrOl Of 12 Step2
The 12 Step2 can control a wide variety of MIDI software and hardware, but it can also be controlled by the USB
MIDI port.
ChanGinG preSetS With prOGraM ChanGeS
When in Standalone Mode, changing 12 Step2 presets via external software/hardware is possible using
Program Change messages. Program Changes sent over USB MIDI will select the corresponding preset in the
setlist — e.g. sending program change 23 will load the 23rd preset in the setlist.
Set which MIDI channel the 12 Step responds to with the “Program Change Preset Control” dropdown menu
in the Settings tab of the 12 Step Editor software.
COntrOllinG 12 Step ledS
The 12 Step keys each have a red LED indicator that can be controlled by sending USB MIDI Control Changes
(CCs), numbers 20 through 33, to the 12 Step2. Any non-zero value (1-127) will turn the LED on, and a zero
value will turn it off. You can control all of the key LEDs simultaneously using CC42.
You can also control the brightness of the key backlight LEDs using CC 69, values 0-127 (this feature only
works with 12 Step2 hardware, older 12 Step hardware cannot dim the backlight).
12 Step responds to LED control messages on the same channel as Program Change messages, which you
can set in the Settings tab of the 12 Step Editor software.
COntrOllinG 12 Step2 diSplay
In addition to the key LEDs, the four-character display on the 12 Step2 can also be controlled by sending CC
messages to the USB MIDI Port.
The four characters on the display are addressed using four CC messages:
• CC 50 = rst character
• CC 51 = second character
• CC 52 = third character
• CC 53 = fourth character
Each CC should be sent with a value between 48 and 90. These values correspond to the following:
• 48-57 = Numbers 0-9
• 65-90 = Letters A-Z
• 58-64 = various symbols/characters (or blank spaces)
For example, to make the third character display the number “3”, send CC #52 with a value of 51.
12 Step responds to display control messages on the same channel as Program Change messages, which you
can set in the Settings tab of the 12 Step Editor software.

1.5 CalibratinG expreSSiOn pedal and Cv OUtS
You can calibrate the expression pedal range and CV voltage output with the 12 Step Editor software. Both
calibration windows can be opened from the “Hardware” menu item.
CalibratinG expreSSiOn pedal
An expression pedal plugged into the 12 Step can be used as a source to control MIDI parameters. Please
calibrate your expression pedal to ensure that you have access to the full range of values.
To calibrate the expression pedal:
1. Plug in your expression pedal. Make sure it is an expression pedal, a volume pedal will not work.
2. Adjust the expression pedal from heel to toe and observe the live values on the left slider. The middle
slider adjusts the min and max thresholds, and the right slider shows the calibrated output value.
3. Put the expression pedal at the zero (heel) position. Adjust the min threshold (middle slider, bottom/
blue handle) until the output slider value is zero.
4. Put the expression pedal at the max (toe) position. Adjust the max threshold (middle slider, top/red
handle) until the output slider value is 127.
5. When satised, click [save] to send the calibration values to the device.
11
12 Step2 hardWare
12 Step2
CalibratinG Cv OUtS
The voltage sent from the CV Outs can be ne-tuned to accomodate drifting oscillators and non-western or
experimental tonalities. Calibration happens by octave or by note with the help of the “Calibrate CV Outs”
window.
Each 12bit value (0-4095) is a scaling calibration value for the listed voltage.
To calibrate a voltage value, measure the CV out with a precision voltmeter, or connect it to a trusted
oscillator and measure the pitches with a tuner. When you adjust a value, the CV is immediately updated so
that it can be measured in real time.
You can directly control the CVs with 12 bit values by using NRPN 1 for CV1, and NRPN2 for CV2.

2.3 Midi paraMeterS tab
The MIDI Parameters tab is where more advanced/detailed MIDI parameters are set. The MIDI channel can be
dened, program and bank changes can be set up, CC settings can be altered, and more.
vOiCe a and vOiCe b
12 Step is capable of outputting MIDI Notes simultaneously on two separate “voices”. Each voice has its own
independent set of “Global Parameters”. This is useful for doubling up synths and controlling them with a single
controller.
There are two columns for each of the MIDI-related options — one for Voice A and one for Voice B. Each voice
can send on a separate MIDI channel, with different transpositions, bend ranges, program change, bank select
messages, and modlines.
2.3.1 GlObal paraMeterS
The top portion of the MIDI Parameters tab contains options related to the behavior of the 12 Step and some
more general MIDI parameters (program changes, MIDI channel, etc.) that remain xed per preset.
Midi Channel
Sets the MIDI channel to output MIDI messages on.
17
12 Step editOr
prOGraM ChanGe
Sets a Program Change value to output whenever the preset is loaded. This is useful for loading specic
presets/settings whenever a certain 12 Step preset is selected.
• Range: 0-127
bank MSb/lSb
Sets a Bank Select message to output whenever the preset is loaded.
• Range: 0-127
tranSpOSe
Sets a transposition amount (in semitones) for the entire preset.
Example: A Transpose value of “3” would transpose all of the preset’s MIDI note output by a minor third
interval.
12 Step2
• Range: ±12
2.3.2 MOdlineS
The lower portion of the MIDI Parameters tab is where you will nd the “modlines”, a set of options/parameters
that dene what MIDI messages the 12 Step will output and how it will output them. Each preset can have up to
six modlines.
The modline section contains the following:
Midi MeSSaGe typeS
Sets the type of MIDI message to output.
Note: Each message type can only be used on one modline per preset, with the “CC” message type being
the exception. The CC message type can be used on two modlines.
The following message types are available in the 12 Step Editor:
nOte - Outputs a MIDI note.
CC - Outputs values on a specied Control Change (CC) number.
18
12 Step editOr
bend - Outputs values as MIDI pitch bend messages.
Channel preSSUre - Outputs values as MIDI Channel Pressure messages.
pOly aftertOUCh - Outputs values as MIDI Note Aftertouch messages.
SenSOr SOUrCeS
Select the type of sensor data to use (e.g. pressure, velocity, tilt, key number).
velOCity
Outputs a value representing the amount of force a key is triggered with. Triggering a key with more force
results in higher values, triggering a key with less force results in lower values.
velOCity (inverted)
12 Step2
An inverted version of the Velocity source. Triggering a key with more force results in lower values,
triggering a key with less force results in higher values.
preSSUre
Outputs the amount of pressure currently being applied to a key. More pressure results in higher values,
less pressure results in lower values. The value will drop to 0 when the key is released.
preSSUre (inverted)
An inverted version of the Pressure source. More pressure results in lower values, less pressure results in
higher values. The value will go up to 127 when the key is released.
tilt
Outputs the amount of bottom-to-top pressure (y-axis) currently being applied to a key. Pressure more
toward the top of the key results in higher values, pressure toward the bottom of the key results in lower
values. The value will return to center (63) when the key is released.
tilt (inverted)
An inverted version of the Tilt source. Pressure toward the top of the key results in lower values, pressure
toward the bottom of the key results in higher values. The value will return to center (63) when the key is
released.
keynUM
Outputs the key number of the currently active key. Keys are numbered in order from left-to-right — they
do not follow the actual labeling on the 12 Step board itself.
19
12 Step editOr
keynUM (inverted)
An inverted version of the KeyNum source. Instead of outputting an incrementing value from 1 to 13,
the inverted version outputs a decrementing value from 127-115.
pedal
If an expression pedal is connected, this source will output the current value coming from the pedal.
Rocking the pedal back (heel down, toe up) results in lower values, rocking the pedal forward (heel up,
toe down) results in higher values.
pedal (inverted)
An inverted version of the Pedal source. Rocking the pedal back (heel down, toe up) results in higher
values, rocking the pedal forward (heel up, toe down) results in lower values.
Gain
Multiplies incoming values by the specied amount. Negative numbers can be used to invert values.
Defaults to a value of 1.
12 Step2
OffSet
Adds the specied amount to incoming values. Use negative numbers for subtraction. Defaults to a value
of 0
CUrve
Sets the type of curve to apply to the incoming values. The available curves include Linear, Sine, Cosine,
Exponential, Logarithmic, and DeadZone (similar to the Linear curve, but this curve has a “dead zone” in
the center).
Min/Max
“Min” sets the minimum value that can be output. “Max” sets the maximum value that can be output.
All values outside the “Min” and “Max” values will be clipped, but they are not ignored. For example,
setting the “Min” and “Max” both to a value of 60 will send 60 every time you press the key.
add/delete MOdlineS
The “plus” button adds a modline (maximum of 6 per preset) and the “minus” button deletes a modline
(minimum of 2). Adding a modline will place a new at the bottom of the list. Deleting a modline will
remove the bottom modline from the list. When deleting a modline, the Message Type and Sources will
automatically be set to “Off”. All other settings (Gain, Offset, Curve, Min, Max) will be preserved.

12 Step2
2.3.3 COntrOl vOltaGe
12 Step2 has 2 programmable CV Outputs. Each output can be controlled locally by the 12 Step keys, or externally
via USB MIDI. If a CV out receives signal from both local and external sources the most recent signal will take
priority.
CV features are only available on 12 Step2, and are disabled if legacy hardware is connected.
lOCal 12 Step2 Cv COntrOl
You can control the CV outs with the 12 Step2 keys. If multiple notes are assigned to a 12 Step2 key, only the
rst note (the note at the top of the key in the Editor) controls CV.
The following sources are available to control the CV outs from the 12 Step2 keys.
• GATE - the CV is set to 5V when a key is pressed, and 0V when the key is released.
• PITCH - the CV is set to a (1V/Oct) voltage that matches the most recent key that was pressed.
• PRESSURE - the CV is set to 0-5V corresponding to the current PRESSURE of the active key.
• TILT - the CV is set to 0-5V corresponding to the current TILT of the active key.
• PEDAL - the CV is set to 0-5V, controlled by the expression pedal input.
• DISABLED - the CV ignores local control from the 12 Step keys.
external USb-Midi Cv COntrOl
You can control the CV outs with MIDI messages sent to the 12 Step2 CV Out port. The CV outs can respond to
MIDI channels 1 and 2, which you can set in the Editor.
The following sources are available to control the CV outs via USB-MIDI.
• GATE - the CV is set to 5V when a MIDI Note On is received and 0V for Note Off. The Gate remains on
until all active notes are turned off.
• PITCH - the CV is set to a (1V/Oct) voltage that matches the most recent MIDI Note On message.
• VELOCITY - the CV is set to a 0-5V voltage that matches the velocity of the most recent MIDI Note On
message.
• BEND / MOD - the CV is set to a 0-5V voltage corresponding to 14 bit (pitch bend) or 7 bit (mod wheel
CC1) MIDI messages.

2.3.4 key behaviOr
Key Mode defaults to playing monophonically- meaning only one key can be pressed at a time. Keys have 4
different Note Modes that determine how the notes are played and held. Select the Key Mode and Note Mode
options to be saved with the preset.
key MOde
“Key Mode”, formerly “Key Safety”, determines how many 12 Step2 keys can be pressed at once.
• Mono: Only one key can be activated at a time.
• Poly: Multiple keys can be activated at a time.
nOte MOde
“Note Mode’’ lets you select how the 12 Step2 keys turn on and off.
• Normal: Notes will turn on when a key is pressed, and turn off when the key is released.
• Legato: Notes will turn on when a key is pressed, and continue playing until another key is pressed.
• Toggle: Notes will turn on when a key is pressed and stay on until the same key is pressed again.
• Hold: Allows toggling between “Normal” and “Legato” note modes using the Select key.
