Getting Started 11 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 4 5 2 Enter 1 -Oct -10 2 Select 3 +Oct +10 9 0 ST E P 4 5 6 7 3 8 1 (1) Keys Keys are where the action happens.
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.
Getting Started 13 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 2 3 4 Keith McMillen MIDI Expander 5 6 POWER MIDI In MIDI Out EXPAND (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.
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. 2.2.2 Specs Dimensions & Weight • Dimensions: 4” x 1.25” x 1.25” (102mm x 32mm x 32mm) • Weight: 2.5 oz.
Getting Started 15 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 ar = 44100 kr = 4410 ksmps = 10 nchnls = 8 /*-------IVORY-------*/ instr 1 ifreq = Enter 1 cpspch(p5) aglis expseg 1, p8, 1, p3 - p8, p9 k1 k2 k3 a1 line oscil linseg oscil 0, p3, 5 k1, p7, 1 0, p3 * .7, p6, p3 * .

Getting Started 19 2.3.5 Adding An Expression Pedal Enter 1 -Oct -10 2 Select 3 +Oct +10 4 9 0 STEP 5 6 7 8 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.
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.
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.
12 Step Editor Enter 1 -Oct -10 2 Select 3 +Oct +10 4 9 0 STEP 5 6 7 8
12 Step Editor 23 3.0 Editor The 12 Step editor allows for up to 64 fully customizable presets to be edited and loaded onto a connected 12 Step. MIDI notes, CC messages, program changes, preset ordering/management — all this and more can be customized using the editor. 3.1 Main Window Overview Upon first opening the 12 Step Editor the main window will be displayed. This is the gateway to everything — customizing the notes on each key, setting MIDI CCs, adjusting settings, and managing presets.
12 Step Editor 24 (4) Connection Indicator: Displays whether or not the editor has made a connection to an attached 12 Step controller. A connection is required to update firmware, send presets to the 12 Step, and alter the 12 Step’s settings. A connection is not needed to edit or manage presets. 3.1.1 Display Name The display name is used to set the name that appears on the 12 Step’s display when a preset is loaded (four characters maximum).
12 Step Editor 25 (1) Preset selection drop-down Clicking this displays a list of all presets. Choosing one loads it as the currently active preset in the editor. (2) Save Saves any changes made to the current preset when clicked. The save button will light up red if any unsaved changes have been made. (3) Save As Saves the current editor settings as a new preset when clicked. A prompt will appear asking what the preset’s name should be.
12 Step Editor Import Presets from v1.0 It is possible to import presets from the previous version of the 12 Step Editor (version 1.0). See the Import All Presets from V1.0 section for more detailed information.
12 Step Editor 27 3.2 Note Entry Tab The Note Entry tab is where each of the 12 Step keys’ MIDI notes get set. Each key can be set up to output anywhere from 0 to 5 notes at a time.
12 Step Editor 28 2. Select one of the five slots. 3. Either use the up and down arrows on the computer keyboard to increment/decrement to the desired note, or type in the desired note number. 4. Repeat for any other notes that may be needed. Alternatively, the keyboard graphic at the bottom of the Note Entry tab may be used to edit keys. (2) Note Entry Keyboard The note entry keyboard is a graphical representation of a keyboard that covers the entire MIDI range — from note 0 (C-2) to note 127 (G8).
12 Step Editor 29 Clear All Keys Completely clears all MIDI notes from all keys. Transpose Up Transposes the selected key’s MIDI notes up by a semitone when clicked. Notes will clip at 127 (G8) if the resulting transposition would place the note out of MIDI’s range (0-127). Transpose Down Transposes the selected key’s MIDI notes down a semitone when clicked. Notes will clip at 0 (C-2) if the resulting transposition would place the note out of MIDI’s range (0-127).
12 Step Editor 30 3.3 MIDI Parameters Tab The MIDI Parameters tab is where more advanced/detailed MIDI parameters are set. The MIDI channel can be defined, program and bank changes can be set up, CC settings can be altered, and more.
12 Step Editor 31 3.3.1 Fixed 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, bend range, etc.) that remain fixed per preset.
12 Step Editor 32 Note: Bank Select messages are 14-bit resolution (a range of 0-16383), as opposed to the standard 7-bit MIDI message (range 0-127). This is accomplished by using two separate messages: an MSB (most significant bit) and an LSB (least significant bit). With 12 Step, values in the Bank field will set the LSB of the bank message — the MSB will be fixed at 0. The MSB is generally transmitted as a CC 0 messages, immediately followed by the LSB as a CC 32 message.
12 Step Editor 33 3.3.2 Modline Section The lower portion of the MIDI Parameters tab holds the modlines — a set of options/parameters that define what MIDI messages the 12 Step should output and how it should output them. The modline section contains the following: 9 1 2 3 4 5 6 7 8 Message Type Source A Source B Gain Offset Curve Min Max Note Velocity Velocity (Inv.) 1.0 0 Linear 0 127 Bend Tilt Tilt (Inv.) 1.0 0 DeadZone 0 127 CC 76 Pressure Pressure (Inv.) 1.
12 Step Editor 34 (6) Curve Sets the type of curve to apply to the incoming values. For a complete list of all available tables (and what they do) see the Curves section of the Appendix. (7) Min Sets the minimum value that can be output. All values below the minimum will be clipped to this value — they are not ignored. (8) Max Sets the maximum value that can be output. All values above the maximum will be clipped to this value — they are not ignored.
12 Step Editor 3.4 Setlist Tab The Setlist allows up to 64 presets to be ordered in any way. This is the order that the presets will appear on the 12 Step when using Select Mode.
12 Step Editor 36 3.5 Settings Tab The Settings tab is home to a couple of adjustable options related to sensitivity of the 12 Step. The Settings tab contains the following: 2 1 GLOBAL SENSITIVITY SELECT SENSITIVITY + — RESET GLOBAL SENSITIVITY SEND FULL VOLUME ON PRESET CHANGE DISABLED + — RESET SELECT SENSITIVITY VELOCITY OVERRIDE DISABLED 3 4 (1) Global Key Sensitivity Sets the overall sensitivity of the 12 Step keys.
12 Step Editor 37 3.6 Menu Bar Options There are a number of useful functions and settings that can be accessed via the menu bar at the top of the screen (Mac OS) or at the top of the application window (Windows). The following options are available in the 12 Step Editor’s menu bar: 12 Step Editor This option is only available on Mac OS. Windows users can find the options listed below in the Help menu. About 12 Step Editor Displays version information about the 12 Step Editor.
12 Step Editor 38 Edit Clear Preset Clears the current preset. All keys and modlines will be set to “Off”. Copy Preset Copies the currently selected preset. Can be used later to paste over a preset or paste to a new preset. Paste Preset Pastes a copied preset to the currently selected preset. This option is only available if a preset has already been copied. Paste Preset To New Pastes a copied preset to a brand new preset. This option is only available if a preset has already been copied.
12 Step Editor 39 3.7 Select Mode Select Mode is used to both change presets and shift octaves on the 12 Step. 3.7.1 Entering Select Mode To enter Select Mode, 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 Select Mode. 3.7.2 Changing Presets To change presets on the 12 Step, do the following: 1. Enter Select Mode on the 12 Step. 2. Press the 12 Step’s Enter key. 3.
12 Step Editor 40 3.8 Ports When a 12 Step is connected to a computer, two virtual MIDI “ports” (or “busses”) are created — 12 Step Port 1 and 12 Step Port 2. They are the “portal” to communicating with a connected 12 Step. The ports allow for bi-directional communication between the computer and the 12 Step (and MIDI Expander if one is connected), and should appear in any MIDI-capable application when a 12 Step is connected.
Appendix Enter 1 -Oct -10 2 Select 3 +Oct +10 4 9 0 STEP 5 6 7 8
Appendix 42 4.0 Appendix 4.1 Sources 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. • Range: 0-127 (no force to full force) Velocity (Inverted) 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.
Appendix 43 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. • Range: 1-13 (left to right) 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.
Appendix 4.2 Message Types Message Types select what kind of MIDI message the modline will output. Please note that each message type may only be used once. As soon as it is placed on a modline it will no longer be available for other modlines. The only exception to this is the CC message type, which may be used twice. The following message types are available in the 12 Step Editor: Note Outputs a MIDI note. CC Outputs values on a specified Control Change (CC) number.
Appendix 45 4.3 Curves All available 12 Step curves: Linear A 1:1 linear “curve”. Values passing through will not be modified in any way. Sine Applies a sine curve to incoming values. Cosine Applies a cosine curve to incoming values. Exponential An exponential table. Lower values rise slowly — higher values rise quickly. Logarithmic A logarithmic table. Lower values rise quickly, higher values rise slowly. DeadZone Similar to the Linear curve.
Appendix 46 4.4 External Control Of 12 Step The 12 Step can control a wide variety of MIDI software and hardware, but it can also be controlled from an external source via USB or MIDI Expander. 4.4.1 Controlling 12 Step LEDs The 12 Step’s LEDs can be controlled from an external software or hardware source using CC messages. Each key has an accompanying red LED that responds to the following messages: CCs 20-33 control the LEDs on the 12 Step keys (one CC per key).
Appendix 4.4.3 Changing Presets With Program Changes When in Standalone mode, changing 12 Step presets via external software/hardware is possible using program changes. Program changes sent to 12 Step Port 1 will select the corresponding preset in the setlist — e.g. sending program change 23 will load the 23rd preset in the setlist. 4.4.4 Using The MIDI Expander It is possible to control the 12 Step LEDs, display, and presets via input to an attached MIDI Expander.
Appendix 48 4.5 Factory Presets Overview The 12 Step comes loaded with a number of factory presets right out of the box. Many presets were created to showcase the various options available, and others were created with interesting chords/ progressions mapped to the keys. All presets will output over both USB and MIDI Expander (if one is connected) on MIDI Channel 1. Note: There are a few exceptions to the channel 1 rule, namely any preset using both Voice A and Voice B.
Appendix 49 SUS9 (“Sus9 Chords”) Each key plays sus 9 chords (root, 4, 5, b7, 9), with the root notes going chromatically from C2 to C3. For example: key 1 plays C2, G2, Bb2, D3, and F3; key 2 plays D2, A2, C3, E3, and G3; etc. In addition, the note mode has been set to Legato. trtn (“Tritone”) The keys are laid out chromatically C2 to C3, accompanied by a tritone interval above each note.
Appendix 50 bLUE (“Blues Bass”) This preset is the same as the Blues Lead preset above, just transposed down two octaves (C1 to C2). PEnt (“Major Pentatonic”) The keys play a major pentatonic scale going from C3 to C4. There are some duplicate notes to prevent incorrect notes from being played. -Pnt (“Minor Pentatonic”) The keys play a minor pentatonic scale going from C1 to C2. There are some duplicate notes to prevent incorrect notes from being played.
Appendix 51 dIA5 (“Diatonic 5ths”) The keys are laid out chromatically from C2 to C3. Notes in the key of C (the “white” keys) will also be accompanied by a diatonic fifth above each note. StC5 (“Stacked 5ths”) The keys are laid out chromatically from C2 to C3, accompanied by two perfect fifth intervals stacked on top. -6tH (“Minor 6ths”) The keys are laid out chromatically from C2 to C3, accompanied by a minor sixth interval above each note.
Appendix 52 -10S (“Minor 10ths”) The keys are laid out chromatically from C2 to C3, accompanied by a minor tenth interval above each note. 10tH (“Major 10ths”) The keys are laid out chromatically from C2 to C3, accompanied by a major interval above each note. -trd (“Minor Triads”) The keys are laid out chromatically from C2 to C3. Each key will output a minor triad when played (root, minor third, perfect fifth). trAd (“Major Triads”) The keys are laid out chromatically from C2 to C3.
Appendix 53 POtG (“Power Chords Toggle”) The same as the Power Chords Normal preset, except the note mode has been set to Toggle. InPO (“Inverted Power Chords”) The keys are laid out chromatically from C2 to C3. Each key will output an inverted power chord (perfect fifth, root, perfect fifth) when played. d_LO (“Drop D -12”) The keys are laid out chromatically from D0 to D1. Each key will output a power chord (root, perfect fifth, octave) when played.
Appendix dSEt (“Drum Set”) This preset is intended to be used with drums — it transmits on MIDI channel 10, which is General MIDI’s “drum” channel.
Appendix 55 4.6 MIDI Note Naming Reference MIDI notes are numbers between 0 and 127, while music notes are lettered A through G# (in traditional Western notation) — there must be a way to convert between the two. There are actually multiple standards for naming MIDI note numbers, which can make things tricky. KMI follows the C3=60 standard for naming/numbering notes. Below is a chart that can help with converting note numbers to note names and vice versa.
Appendix 56 4.7 Changes From 12 Step V1.0 New tabbed interface All new makeover for the 12 Step editor! Related parameters have now been grouped together and moved to different tabs. Less information overload! Presets are now numbered from 1-128 Previously the 12 Step’s presets were numbered from 0 to 127. They are now numbered from 1 to 128 to make things easier on mere humans.
Appendix 57 4.8 Troubleshooting Problems may pop up every now and then when using the 12 Step — here are some suggestions that can potentially solve them. Connectivity Issues Check that you’re using the correct USB port on the 12 Step There are two USB connectors on the 12 Step hardware — the main USB port (the USB B connector labelled “USB”) and the Expander port (the mini USB connector labelled “Expand”). When connecting to a computer, always use the main USB port.
Appendix 58 Connect to a different computer If the 12 Step is not making a connection to the computer at all, it is recommended to try connecting it to a different computer. If it works on the new computer, try the original one again. In some circumstances we have seen this solve connection issues. Mac OS CoreMIDI “bug” There is an interesting (potential) bug in CoreMIDI on Mac OS that can lead to some connectivity issues — not just with 12 Step, but with any class-compliant MIDI device.
Appendix 59 12 Step. Because of this it is highly recommended to never edit the 12 Step with other audio applications open — it could lead to connectivity issues, and a very confusing, frustrating experience. This does not apply solely to KMI products — this will have an effect with every class-compliant MIDI device.
Appendix 60 4.9 FAQ 4.9.1 How do I contact KMI support for questions about my 12 Step? Support can be reached by submitting a support ticket at the following website: http:// www.keithmcmillen.com/support Before submitting a ticket it is definitely a good idea to read through the rest of the FAQ section to make sure your question hasn’t already been answered. 4.9.
Appendix 61 4.9.5 Does reloading or updating firmware reset my presets? Yes. A firmware update or reinstall will reset the 12 Step’s onboard presets to factory settings. If you have any custom presets you will need to resend them to the 12 Step using one of the editors. 4.9.6 How do I update/reload my firmware? There are a few ways firmware can be updated on a 12 Step: automatically by the editor, manually with the editor, or manually without the use of the editor.
Appendix 62 Mac 1. If you have not already, download and install SysEx Librarian from http:// www.snoize.com/SysExLibrarian/ 2. Download or locate the firmware file you would like to install. Zips of the current version and past versions can be downloaded here: http://files.keithmcmillen.com/ downloads/12step/sysex_files 3. Plug in your 12 Step and open SysEx Librarian. 4. Click “Add...” in the lower-left corner of the screen.
Appendix 63 4.9.7 Is there a way to reset the 12 Step back to factory settings? Yes, it is possible to reset both the 12 Step to factory settings. All that needs to be done is a firmware reinstall (we just went over this in a previous question) — this will revert everything to factory settings and presets. Instructions on how to reinstall firmware can be found here. 4.9.
Appendix 64 4.9.11 Can I program each key to output different MIDI messages? The only thing that can be customized per key on the 12 Step is what MIDI notes are output when pressed. All other MIDI options (program changes, CCs, aftertouch, etc.) are global to all keys. 4.9.12 Can I control the 12 Step LEDs/Display from an external source? Yes. The 12 Step LEDs and display can definitely be controlled from an external source.
Appendix 65 In order for the 12 Step’s USB connection to work properly, it must be connected to a device that can act as a USB “host” for class-compliant MIDI devices. Host devices almost always have a USB A connector on them (the more rectangular-shaped connector, like the ones on a computer). A nonhost device, or a “slave”, generally has a USB B connector (the more square-shaped one, like on the 12 Step).
Appendix 66 different values across the pedal’s travel. At KMI we use Roland EV-5 expression pedals without issue. Third, check to make sure that your expression pedal operates on the correct voltage. All KMI gear operates from 0 to +5 volts. If your expression pedal goes beyond that there will be a lot of pedal travel that appears to do nothing. Note: Volume pedals do not work with the 12 Step or any KMI controller with expression pedal input — at least, not without some modifications...
Appendix 67 3. Look in the MIDI window. If the MIDI window is not visible, go up to the Window menu up top and select “Show MIDI Window”. 4. Look for a device named “USB MIDI Device” and click it. 5. Delete the device by pressing the Delete key on your keyboard. 6. Plug the 12 Step back in to the computer. A new device should appear in Audio MIDI Setup with the proper name, “12 Step”. 4.9.24 I see there is a new update. Should I update right now? The day before my show? No.
4.10 Safety Precautions Medical Devices 12 Step may emit electromagnetic fields. These electromagnetic fields may interfere with pacemakers or other medical devices. If you wear a pacemaker, maintain at least 6 inches (approximately 15 cm) of separation between your pacemaker and 12 Step. If you suspect 12 Step is interfering with your pacemaker or any other medical device, stop using 12 Step and consult your physician for information specific to your medical device.
