Welcome
Welcome and thank you for your purchase of a Liquid Foot+ Series MIDI controller. We hope you enjoy the product and have
many years of great use from it.
Like other Liquid Products, the Liquid Foot+ Series controller was designed to be flexible and full featured. As time goes on,
additional features and functions will be added. You can expect to receive these benefits for free in the form of firmware
updates that you can downloaded from the web-site, and install in seconds.
Please check the download section of our web-site www.FAMCmusic.com for the latest firmware, user guide and other
supporting information and utilities as they become available.
Thank you for your support and enjoy your Liquid Foot+ Series MIDI Controller.
This Quick Start Guide will give you the basics of using the controller.
NOTE: While this guide will show prompts and discuss buttons and the meaning of prompts on the 12+, it should be assumed
that the LED version (LF+ 12) acts in the same exact way. In fact, we attempted to have both devices act as if they were the
same device. They are interchangeable in user options, programming and expansion possibilities. Recently we have extended
the interoperability and as of v1.10 of firmware, all LF+ Series controllers can share programming files. This means you can
program your rig for one device, and simple copy the programming via the editor to any other LF+ device and it will function
immediately.
From Liquid Foot Pro to the + Series, what is new?
The + series of controllers take all of the great features of the PRO line, and add a few major concepts, and several new
hardware features. The + series introduces the concept of PAGES. There are 50 pages available in the controller. These pages
can be switched at any time, via menu commands, an assigned button command, or via MIDI programming.
Each page contains setup parameters along with the ability to program up to two functions for each of sixty (60) physical
switches. While the controller itself will not have sixty switches, it will have access to those switches via MIDI commands, or
the connection of an expander or another LF+ product. Each controller can be assigned to start at any particular physical
button number, allowing for massive flexibility in your layout design.

6
While a Page contains the programming for the buttons, the buttons themselves have various parameters as well as
functionality as defined in the active page. A button can be programmed to act like a preset switch, and IA (effect) switch, a
menu command, a page switching function, and more. There are over 20 special commands that can be assigned to a button
slot. Again, two slots exist for each button on a page.
There are many enhancements, added features and tons of flexibility, like the option to control the color of display for ANY and
ALL buttons, and Slots. You define the function, the color and the layout--- or just use any of the pre-built pages to get started
right away.
Summary of Recommendations
PLAY. PLAY. PLAY. Then PLAN. PLAN. PLAN.
Get used to the LF+ controller. Play with commands, features, pages, etc… Modify global settings to get used to the feature rich
customization and flexibility offered. Once you are comfortable- then plan your layout, your functions. Then program. Taking
time to plan your layout on paper will greatly enhance your ability to get up and running quickly.

Operating Guidelines
Which CABLES Should Be Used?
Expression Pedal Ports 1-4
Your controller comes with four (4) expression pedal ports. Any pedal wired for expressional pedal usage (TRS Stereo
cable). Any standard POT in the range of 5k –25k should work fine. Proper wiring will have the wiper (center of POT)
connected to TIP of TRS plug. The Sleeve will be on the lower (heel position) and the ring will be in the upper (toe
position).
Wiper(T)
Heel position (lower end of POT)(S)
Toe position (upper end of POT)(R)
[Plug to expression pedal]
If you are using the expression pedal as a button, then you can either use a standard a standard button (connecting Tip
to Sleeve momentarily during the button press). There are many buttons on the market that are fully compatible with
the LF+ port.
You may also set an expression pedal port to process two buttons. Both buttons should be connected to the same plug
and wired together as follows:
1K ohm Resistor 1.8K ohms Resistor
RING(R) Sleeve (S)
SLEEVE (S)
TIP(T) TIP (T)

9
Expansion Jack A & B
Your controller comes prepared to integrate expansion models and other peripherals that will be developed. The
expansion modules come with instructions indicating the proper wiring configuration. The expansion system was
designed so that you will be able to daisy chain from one device to another, allowing up to 50 devices to be connected to
each other at one time. Clearly this is overkill, but it’s the Liquid way.
When connecting multiple LF+ controllers together, please use a standard CAT-5 (Ethernet) cable from one unit to the
next. The signals are NOT compatible with any other manufacturers equipment and should not be used in conjunction
with other equipment unless specifically stated by FAMC. These connectors are not compatible with the LF PRO series
of controllers. This new interface developed by FAMC will support all Liquid products from this point forward.
For more detailed information, please see the “Master / Slave” configurations (Working with Expanders)
MIDI IN
The MIDI IN connector should be connected to any device that will be used to control the Liquid Foot. This maybe your
computer, a midi foot controller, or perhaps another Liquid Foot (See Master / Slave section). The Liquid Foot+ will
respond to any valid Sysex messages, any valid master/slave processing and standard midi commands sent to its
assigned midi channel (see global menu section).
Do not use the MIDI cable system for interconnection between multiple LF+ controllers. See the Expansion Jack A & B
section for further information.
MIDI OUT (MIDI IN and Power)
The Midi Out port normally functions as only a midi out connector. Usually data transmitted from this interface will be
from the Liquid Foot itself. In the global menu, you can turn the MIDI THRU ON. When ON, data from the MIDI IN port
will repeat on the MIDI OUT port.
The MIDI OUT connector is designed to be used as a 5 pin, or as a 7 pin interface. It carries standard MIDI OUT, with the
inclusion of MIDI-IN, and Phantom Power (from pins 6/7). DO NOT attempt to power external devices from this
interface. If using phantom power, you must deliver at least 9-12V AC/DC, 800ma per LF+ connected.
When using this port for MIDI-IN data, DO NOT connect another midi device cable to the MIDI IN of the LF as the system
will not process both channels simultaneously.

10
Care and Cleaning
Do not use solvents to clean the front or back panel of the unit. A lightly damp (water only) cloth can be used. A soft
cloth is recommended as the Anti-Glare LCD screen(s) will scratch if rubbed with an abrasive material. DO NOT use
liquids around the unit and do not pour water, solvents or any other type of liquid on the unit. Yes, it is a “Liquid” Foot
Controller- but like most electronic devices, it is not tolerant of Liquids! Go figure.
Maintenance
Buttons: Periodically tighten the top nuts holding the 8, 12, or 24 buttons on the top of the unit. Normal use and
excessive wear and tear could loosen these nuts over time. DO NOT UNSCREW THE BUTTONS FROM THE TOP PANEL
FOR ANY REASON. Purposefully loosening the nuts from the buttons could cause damage and will require maintenance
from the inside of the device to tighten.
Installing Add-On Modules
Instructions will be included for the specific add-on module you purchased. NEVER PLUG OR UNPLUG an expansion
module or add-on to expansion port A or B without first removing power from all units. Please follow all other
installation steps as delivered with the add-on unit.
Product Support
I know, we don’t read user guides. In fact, in writing this user guide, it is assumed no one will read this very paragraph.
Kind of like asking if a tree makes noise when it falls and no one is around to hear it!
Should you have questions or issues, please start by referring to this user guide for basic operating information. Also,
check www.FAMCmusic.com for the latest firmware, user guide updates, video tutorials and access to the user forums.
If your questions are still unanswered, feel free to fill out a trouble ticket on the web and we will provide an answer as
soon as possible.

The Basics of MIDI
What is MIDI?
So you bought a MIDI controller and you are now saying, OK, I needed one, but what is it? Where do I start? What is
MIDI anyway? MIDI is a very simple communication protocol used for hardware devices to “talk” to each other. Think of
this as a language that initially started as a way for musical devices to pass along musically oriented information useful
for real-time music message exchange- messages like “turn a “C” notes of a synthesizer on and off as an example. Think
of MIDI mainly as a “language” with specific rules, commands and vocabulary that all devices follow.
The MIDI “language” is passed along as a digital signal, and is NOT an audio signal. There are no audio signals found,
passed or otherwise used in MIDI. Just simple commands in digital form. Think of MIDI as a beeps and buzzes that you
used to hear when using MODEMs that connected one computer to another via phone line. It’s basically the same thing
in concept. The language of MIDI is structured into 8 core “messages”, with lots of subsets of those messages. The core
messages mostly used are:
NOTE ON,
NOTE OFF,
CONTINOUS CONTROLLER MESSAGES,
PROGRAM CHANGES, and
SYSEX MESSAGES
There are other commands which we will ignore for this quick primer, however, the Liquid-Foot+ Series controllers
allows you to address all of the standard midi message types, and the extended ones as well.
Devices that speak the language of MIDI also have a specific connector that is designed to support the transmission of
MIDI messages and information (called MIDI OUT port). This is the port used to send MIDI commands. Devices that
Listen to the language have a specific hardware port referred to as the MIDI IN port. This is the port that receives
commands that are being sent from another device. A third type of connector is the MIDI THRU port. MIDI THRU
connectors usually just act like another MIDI OUT port which transmits a copy of whatever message(s) that come into
the MIDI IN port of the same device.
You can connect as many MIDI devices as you would like in a daisy chain fashion. The MIDI OUT of the first device in
your chain will connect to the MIDI IN of the next device. Then that second device will connect its MIDI OUT (OR MIDI
THRU) connector to the MIDI IN of the next device in the chain, and so on. There are more complicated signal set-ups

12
(using routers, mergers, etc…), but the basic concept is that MIDI OUT ports will send messages from a device and there
needs to be a listening MIDI IN port to receive that data.
MIDI Channels
Like any other spoken language, the vocabulary (commands discussed above) will be meaningless if we can’t identify
specifically who we are talking to in the crowed room. Yelling commands when no one is listening wouldn’t be very
rewarding. We essentially would be talking to ourselves (that's not always a bad thing!), but for MIDI- it is required that
someone is listening or nothing will happen. Most commands you will use require that you define who the message is
intended to reach. Meaning, if we are sending a command, we need to tell all the devices on the MIDI daisy chain which
device we are trying to speak with. The concept of MIDI channels is our way to do that. MIDI allows up to 16 channels in
one network. That doesn’t sound like much, however, think about how many MIDI devices you have in your RIG? More
than 16? If so, you’re not reading this section and have figured it out by now. Ha.
When we connect a device to the MIDI network via cables from a MIDI OUT (THRU) connector to a MIDI IN connector
on a device, we would also need to assign a unique MIDI CHANNEL to that device. Usually there is a setting in the device
that lets you set the MIDI channel from 1-16. Just make sure each device connected as a different MIDI Channel
assigned. The number itself doesn’t matter, there is no real set formula for which channel you assign to which device,
just make a note of who is listening to which channel.
Putting it together
So we have a network of connected devices using MIDI IN and OUT connectors. We have set each device to a specific
MIDI channel—great, we are ready to start sending commands to those devices so we can tell them what to do. Well
how do we know what MIDI commands a device is listening for? Great question. Usually a hardware device that is
compatible with MIDI will have a MIDI IMPLIMENTATION guide somewhere in their user guide. This guide will tell you
what messages the device is capable of sending, and also what messages it is listening for. Use the guide to help you
define what commands you need to send the device to achieve your desired results. Most of what you will need will be
accomplished using either a Program Change (PC) message, or a Continuous Controller (CC) message. Let’s look at
those two messages below.
Command: PROGRAM CHANGE (PC)
Let’s make some noise on an effects unit! We have to assign the device a MIDI channel. Ok, so now let’s say that it’s
listening to MIDI CHANNEL 1. Great. We want to select a preset (patch) or memory area of the effects unit to load so we

13
can hear it. That's where the PROGRAM CHANGE message comes in. It's a MIDI standard message for the purpose of
telling a device to change patches. It can be used for many things, but you can usually count on this message working as
we need it to. Devices handle presets differently, some use Banks, others not. If your device has more than 128 presets
(patches) available, then it uses banks in some fashion. If it is less than 128, you need not worry about Banks.
Before we begin with Program Commands, lets discuss Banks briefly. All devices can provide different numbers. MIDI
in general provides direct access for up to 128 patches. These presets are sometimes numbered from 0 to 127, and
other times numbered from 1 to 128. For devices that show presets from 1-128, it is important to know that those
numbers are for human readability. The actual MIDI data will be between 0-127. So 1 will actually be a data value of 0
to the MIDI system itself.
In devices that support more than 128 presets (patches), the likelihood is that these sounds will be organized into
banks, with each bank containing no more than 128 sounds. The MIDI protocol now includes the facility to switch from
one bank to another, though some older instruments have non-standard bank change commands. Usually a Bank
change requires a CC message (described below). Again, the commands required are usually explained in their MIDI
Implementation guide.
So now we have the basic understanding. A Program Change message will be made up of 3 parts, (1) The Command
“Program Change (PC)”, (2) the MIDI Channel we are talking too, and (3) the Preset (patch) # we want to select ( a
number between 0 and 127).
Let’s create a sample command now. We want to talk to a device on MIDI channel #1. We want to tell the unit to turn on
Preset #10. The Command will be “Program Change Midi Channel #1, with Preset 10). Pretty simple right--- yep, it is
that simple.
On the LF+, this Command might look something like this on 2nd line of the LCD: 01 | 01|5|10. The first 01 is telling us
that we are programming the first command of the sequence (perhaps the only command). The Second 01 is the midi
channel (the screen’s top line say “Midi Chan”. The 5 refers to the 5th midi command, and the top of the screen says
“Program #” so you know it's a Program Change. The 10 at the end is the preset # for the program Change message.
Not hard once you are looking at the screen.
Command: CONTINOUS CONTROLLERS (CC)
While CC functionality can get complicated, it’s not that hard to understand for most of your purposes. What are CC
messages used for? Ever move an expression pedal up and down to control your Volume? Well, how did the effects unit
know to increase the volume when you pressed the expression pedal down? How did it know to lower the volume

14
when you pulled back on the pedal? Another question, how did your effects unit shut off the Delay effect when you
pressed a certain button on the MIDI controller? How did it know to turn it back on when you pressed the button again?
You guessed it, the CC message is responsible for all of those things.
A MIDI Channel can have up to 128 CC messages that it can respond to. They are numbered from 0 to 127. Since we
usually assign a single MIDI Channel to one device, it means that any one MIDI device in our system can respond its
own CC message from 0 to 127. Not all devices implement all 128 CC messages. Look at the devices MIDI
implementation guide to determine which CC messages it will respond to.
So how did the expression pedal change the volume? Let’s answer that while explaining the CC MIDI message. CC
messages have 3 parts to the command. First, we need to tell the command which MIDI channel (device) we are talking
to. Next, we need to tell the command which of the 128 CC numbers we are using. Finally, we need to tell the command
what data value we are storing in the CC#. CC data values are between 0 and 127.
There are a couple of conventions used for the data value worth noting. For commands that use CC numbers to turn
things ON and OFF, the data value of 0 usually represents OFF, and 127 represents ON. For effects like volume, the
entire range of values (from 0-127) are used to provide relative % of total value. So 0 is NO VOLUME and 127 would be
full VOLUME.
So putting it together, let’s assume a device on channel 1 has assigned CC#7 to Volume. Now we need to tell the
speaking device (like the Liquid Foot+ MIDI Controller with the expression pedal connected), that we will transmit the
expression pedal values to CC #7 on MIDI Channel 1.
When you press the expression pedal, the MIDI CONTROLLER will automatically figure out the position of the pedal
(with a value between 0 and 127), and automatically (continuously as you move the pedal) send the commands to the
device which will change the volume as you move the pedal.
The same concept is true for turning effects on and off. Let’s say an effects unit assigned CC#12 to Delay. We could send
a CC command to CC#12 as the CC number, with a value of 127 (ON). This will tell the effects unit to turn ON the delay.
If we sent a CC command to CC#12 with a data value of 0 (OFF), then the effects unit will shut of the delay effect.
On the LF+, this Command might look something like this on 2nd line of the LCD: 01 | 01|4| 012 | 127. The first 01 is
telling us that we are programming the first command of the sequence (perhaps the only command). The Second 01 is
the midi channel (the screen’s top line say “Midi Chan”. The 4 refers to the 4th midi command, and the top of the screen
says “CC #” so you know it's a Continuous Controller. The 12 is the CC# (our delay per above), and the 127 is the Data
Value (ON). So we have a CC#12 Message on MIDI Channel #1 with a Data Value of 127 (ON). Not too bad!

Special Commands During Power Up
Powering on the Unit will always bring you back to the point you were last at before it lost power. Same preset, mode,
etc… There are certain commands that you can trigger by pressing buttons while powering on the unit.
Press and hold the following buttons while powering on the unit. Do not let go of the buttons until the unit completes its
startup process and the LCD changes to reflect your special command:
MENU System: Force the unit to enter Menu system before
do anything else.
Force unit to wait for MIDI Firmware before doing
anything else.
Expression Pedal Testing. LCD Display will show read-out
on a scale from 0-409. All buttons not pressed should
default to 409.
Force Preset Mode as startup mode
Force Song Mode as the startup mode
Force Expander mode as the startup mode, and set the
unit as an expander
+ + +
CAREFUL. THIS PERMENENT. This will reset the unit to
all default settings and Page definitions, and it WILL
completely ERASE all of your programming to the system
defaults.
+ + +
CAREFUL. THIS PERMENENT. This will reset the unit to
all default global settings. This will NOT erase your
presets, songs, set-lists, pages, IA-Slots, or Sysex Messages.

The Basics of Setting Up and Programming the LF+
Where Do You Start?
A device with so much flexibility can be overwhelming to start using. Where do you begin? Lets begin with the concepts
of the LF+, and then go through some steps. The LF+ Series of Controllers have several interrelated sub-systems
working in tandem to achieve simple to very complex setups. We need to understand the building blocks of these sub-
systems before we can just jump in.
PRESETS: One of the basic building blocks of the LF+ is the concept of a Preset. The LF+ has 384 Preset locations that
you can use to be the kickoff point for a certain “sound”. Presets have a set of parameters that control their behavior,
and also allow you to “define” how your equipment in your MIDI RIG should be set-up. Each preset has its own settings,
programming commands and initial settings for your MIDI equipment. This concept essentially allows you to create
“sounds” (presets) by loading program changes, setting the state (ON or BYPASS) of each of your effects, and much
more.
Each Preset will always have access to all 60 of the IA-Slots (discussed below). This means that Presets can define
which state to put each of your 60 IA-Slots and further will change those IA-Slots when the preset is selected.
So it is important to think about what sounds and configurations you need to have access to. Each unique version of a
sound, or initial setup of your IA-Slot commands will be defined in a unique Preset.
IA-SLOTS: Instant Access (IA) Slots serve two purposes in the LF+ Controllers. First off, there are 180 of these Slots that
you can program. While there are some very powerful and complex programming that can be applied to these Slots, in
the most basic of uses, a single IA-Slot would be used to turn an effect ON and OFF. So for each effect that you
potentially want to control (either VIA a button on the controller, or via a setting within a preset), you will need to
create an IA-Slot.
60 IA-Slots at a time are available to a preset based on the current/selected IA-MAP (default is IA-Slot 1-60). This
means that when you load a preset, if its told to process the initial states of IA-Slots, the preset will Update the state
(turn it ON/OFF, etc…) and will send those commands. It does not matter if you have a button on the controller
available to control the IA-Slot, Presets that are told to work with IA-Slots will always process them.
IA-Slots that are assigned to buttons on the controller will be available for the user to toggle (or other).

SONGS: There are 254 song locations in the LF+. Each Song can have a specific set of 24 presets, which are put in
whatever order you define for that particular song. By selecting a song, you are telling the LF+ to re-arrange the presets
to match the order defined in the song. Songs are simply a folder of presets put into a particular order.
SET-LISTS: Set-Lists are similar to songs. But unlike songs which sort presets into a particular order, Set-Lists do a
sorting of songs in a particular order that you define per preset. So when using the LF+ in Set-List mode, the first thing
you will do is load the Set-List. The system will know that you ordered the Songs into a particular order. Now as you
press SONG UP or SONG DOWN buttons, you will scroll through the songs in the order that you set for the set-list. When
you select a song, the system will then have access to the presets (in the order) that you loaded into the Song definition.
PAGES: There are 50 pages that you program and have access to at any time. What is a page? Well imagine your
controller being a blank slate of buttons. Those buttons need to be assigned things to do. Pages are used to define a set
of behaviors, and a set of things that each button can do. In fact, on each page, a button can do up to two different
things. When your needs become very complex, using pages and flipping between pages allows you to redesign the
“layout” in real-time of your controller. Pages can even be programmatically changed at a song, preset, or IA-Slot level.
What can you assign to a button? Good question. There are four types of items, (1) a Preset holder, (2) an IA-Slot, (3) a
special command (like BANK UP, etc…), and switch page commands. With the ability to utilize two commands per
button, you can image putting a BANK UP as function #1, and BANK DOWN as function #2 on the same button-
depending on the behavior you set for that particular button, its possible to tap the button for Bank UP, and double tap
the button for bank down. You used one button to do two powerful things!

The User Interface
Buttons
The Interface on the LF+ 12, LF+ 12+, and Pro+ are identical in almost all regards. One obvious difference being that the
LCD’s above the buttons on the 12+ will display prompts and additional information that you will not see on the 12.
There are only a handful of functions available on the 12+ that do not exist in the 12, and those features will be
highlighted in the User Guide.
Special Key Combinations
Buttons 1 through 12 will be identified as through .
Special Commands are a combination of buttons held together. They are:
MENU: + or it is referenced as
SCROLL: + or it is referenced as
PAGE SHIFT: + or it is referenced as for 12, 12+, Pro+
PAGE SHIFT: + or it is referenced as for JR+

The MENU User Interface
One of the first things you will want to do is configure your new unit. Almost all functions are found in the menu
system.
From any operating mode, press both + together to enter the menu system. When the first line of the
main LCD begins to display the menu title, you may let go of both buttons.
Once in the menu system, you will notice the and buttons are now lit
white.
You will also notice that the and buttons are now lit yellow/orange. These colors
indicate we are in a menu and also indicate that the button itself is usable in the current MODE/SCREEN we are on.
Thus, we can press the MENU LEFT or RIGHT, EXIT, and/or SELECT buttons.
To scroll backwards in a list to the beginning of the current options available, press . To scroll
forward through a menu list, press .
