It can be used for receiving MIDI patch data, program changes or can be used to connect multiple Mastermind GTs together and allow them to control each other.
Basic Operation Right out of the box, the Mastermind GT is configured like a standard MIDI controller. The preset buttons are green and instant access buttons are blue. Buttons with other functions are indicated by color and text label. The Mastermind GT is configured to control a single Rack Gizmo (our flagship audio loop switcher / function switcher), and to send program change messages on MIDI channel 1.

These are typically used to send program change messages to effects processors and to turn on or off multiple loops on audio switchers.
By default, the Instant Access buttons are set up to control a Rack Gizmo, but they can be programmed to control pretty much any MIDI device, even more than one device at a time. Please refer to the Editing Buttons section for information on how this is done. Button Pages The Page / IA Store button allows you to switch between multiple pages of buttons.
Initial Setup - Adding a Device The first thing you’ll probably need to do with the Mastermind GT is to add a device. This informs the GT about what it’s connected to and what it needs to do to control that device. The Mastermind GT has an internal database of information about popular MIDI devices, so often times you might only need to select the device from a list and the Mastermind GT will do the rest of the setup for you.
Once a device slot is selected, you are taken to the Device Edit screen. Select the Type button in the upper left hand corner to set the type of this device. Edit Device 1 Type ??? Done Done Select You will be presented with a list of device manufacturers. Select your manufacturer from the list, then select the model of the device in the next list that is presented.

Dest Preset indicates the first of the presets on the Mastermind GT that will be renamed. Once you press the Start button, the Mastermind GT will query your device starting at the preset indicated by Start Preset.
Editing Buttons The basic device setup in the previous section is typically enough you get you started using a new device. However, you’ll probably want to change the button arrangement of the controller to your liking. On the Mastermind GT, any button can be set to perform any function, so be sure to take advantage of this ability! Swap Buttons The simplest way to rearrange buttons is to use the Swap Buttons function. This function simply swaps the location of two buttons.

The Assign Buttons menu is designed to be a quick way to set up your buttons. To do more detailed editing, you can use the Edit Button menu, which is described next. Low Level Editing If you need more control over your buttons, you can edit the Actions assigned to each button. Button Actions are a list of things a button does when it’s pressed. This could be sending a MIDI message or changing a parameter or mode on the Mastermind GT itself. You can define up to 10 actions for each button.
You can continue this process, adding multiple Actions to a button. When a button has more than one Action defined, it will perform all of the Actions in the list, in order from left to right, top to bottom. So, if you wanted to, you could have a single button enable an effect on one processor, turn on several effect loops on a loop switcher, play a note on a synthesizer and start a sequencer! The various Action types and their parameters are described in more detail in the Action Edit section.
Editing Presets Each of the Mastermind GT’s 384 presets can send different MIDI Program Change messages to each of the connected devices, making it a quick way to switch from one sound to another. By default, the Mastermind GT sends consecutive program change numbers to each device. Selecting preset 1 sends program change 0 to each device, selecting preset 2 sends program change 1 to each device, preset 3 sends program change 2, etc.
Pressing any of the active device buttons brings you to the PC Edit menu: No Program Edit PC Message Effect Gizmo Preset 7: Shred Done Done - Program 7 + - Bank 0 + You can press the Program or Bank buttons to edit the program (PC) and bank numbers, or press the + or - buttons to adjust the numbers up or down. Pressing No Program will prevent the Mastermind GT from sending a program change to the device when loading this preset. Press the Done button when the numbers are set correctly.
Song and Setlist Mode For live performances, your Mastermind GT presets can be arranged into Songs and Setlists. Using this feature allows you to group presets by song and makes it easy to rearrange those songs for each performance. A Song is a group of presets – up to 16 of them – that are selected for use in a particular song. Each preset is typically chosen for the sounds needed in different parts of a song: intro, verse, chorus, bridge, solo, etc.

Expression Pedals The Mastermind GT has four ports that allow you to connect external expression pedals. An expression pedal can be used with MIDI-capable effects processors to provide real time control of different parameters: volume level, echo rate, etc. The Mastermind GT translates the position of the pedal to MIDI Continuous Controller messages and sends them out the MIDI Out port. The effects processor receives these messages and alters the effects accordingly.

To set this up, you first need to select which parameter you wish to control. If you’re using the expression pedal to control a wah effect, you would want to have the expression pedal switch control the effect processor’s “Wah” or “Wah On/Off” parameter.
The last step is to choose at what point in the pedal’s travel the switch happens. Move the pedal to that spot (typically not quite all the way down or not quite all the way up), then press Set Switch Position. The pedal position will be remembered and the selected function will switch on and off as you move the pedal up and down. Expression Pedal Grouping Having four expression pedals in front of you can make for a large pedalboard. To help alleviate this, we’ve added expression pedal grouping.
External Switches The Mastermind GT supports up to four external switches. These can be used to add switches to remote locations, to add different types of switches for specialized functions like tap tempo, or simply to increase the number of available switches. There are two external switch jacks on the rear of the Mastermind GT labeled “Switch 1/2” and “Switch 3/4". Each jack can take a single switch or a double switch with a TRS (tip-ring-sleeve) plug.
Remote Mode You can connect multiple Mastermind GTs together and have them operate in unison. Selecting a preset or pressing an Instant Access button on any controller will cause the other controllers to switch similarly. This is a great feature for both stage and studio - you can have multiple controllers at different locations on the stage, have an additional controller operated off-stage by a tech, or have controllers in both the studio and the control room.
External MIDI Control The Mastermind GT can also be controlled by an external MIDI device such as a computer, sequencer or other type of MIDI controller. To enable this feature, set the MIDI Rx Ch parameter in the MIDI Settings Menu to the desired MIDI channel. Any bank or Program Change messages received through the Remote In or USB B ports on this channel will cause a preset change on the Mastermind GT.
Other Special Features Global Preset The global preset, if enabled, is an additional preset that can be accessed from any other preset simply by pressing the currently selected preset button again. This is typically used to set up a preset that is your “standard” or “go-to” guitar sound that’s always accessible, no matter what bank of presets you’re currently using. To enable the global preset, enter Setup Mode and press the Preset 2nd (preset 2nd press) option. Set it to “Global”.
Loading and Saving Settings to a USB Flash Drive The Mastermind GT allows you to load and save settings to a USB flash drive. You can use this feature to back up settings, transfer settings from one Mastermind GT to another GT, or to transfer settings to or from a computer. The drive is plugged into the USB A port on the rear panel. Loading and saving are done from the System Menu. To get there, hold both soft buttons under the display. When the setup menu appears, select System Functions.
Connecting to a Computer In addition to the USB flash drive support, the Mastermind GT’s USB B port allows you to connect your controller to a PC or Mac with a USB port. The Mastermind GT is a class-compliant USB MIDI device, which means it doesn’t need additional driver software. The Mastermind GT will appear as another MIDI device in your system, and will work with any MIDI-enabled programs you’re using.
Upgrading Firmware The Mastermind GT is designed to be easily upgraded by the user. Firmware updates will be periodically made available on the RJM Music website. These updates will add support for more devices and add other new features. The firmware upgrade process is simple: first, download the upgrade file from the RJM Music website using your PC or Mac. Copy the downloaded file to a USB flash drive. All RJM firmware files end in the extension “.
Setup Mode Reference Setup mode allows you to configure all aspects of the Mastermind GT, from the MIDI messages it sends to the way information is displayed on the screens. To enter setup mode, press and hold the two soft buttons located under the main display. After about 2 seconds, the display will change, indicating you’re in setup mode. In Setup Mode, the footswitch buttons switch from their normal functions to become a menu for selecting setup options.

The letters are placed in groups of two or three. Pressing a letter button will select the first (leftmost) letter, and pressing the button again quickly will move to the next letter. For example, pressing the OPQ button once will place an “O” on the screen. Pressing it again quickly will change the “O” to a “P”. Pressing it a third time will change the “P” to a “Q”. If you press another letter or wait about 1.5 seconds, the letter will be accepted and you will move to the next letter position.
Main Menu The first menu you see upon entering Setup Mode allows you to configure some system options as well as access submenus to edit devices, buttons and presets. Current Pg. – Sets the currently visible button page. This is useful if you accidentally find yourself on a page that doesn’t have a Page Select button defined. Set List – Pressing this button allows you to select which setlist is active, and enables Song and Setlist Mode. When set to “All Songs”, all 252 songs will be used as your setlist.
Pdl Group – This button selects the grouping of expression pedals. Pedal grouping allows you to switch your expression pedal to control different parameters. You can have expression pedal 1 send the messages assigned to pedal 2, 3 or 4 with the press of a button. The default value is None, which indicates no grouping. Other possible values are [1 2] 3 4, [1 2 3] 4, [1 2 3 4], [1 2] [3 4]. Please refer to the Expression Pedal Grouping section for more details.
Edit Device Menu Type – Sets the type of device that is in this slot. The menu first prompts you for the device manufacturer, then the device model. If your device is not listed here, you can use the Generic setting, which will allow you to manually configure parameters. Name – Allows you to edit the name shown for this device. MIDI Ch – Sets the MIDI channel for this device. This number needs to be the same as the channel that is set on the device itself.
Init PCs All 0 – Initializes all presets for this device. Selecting this option will initialize all presets on the Mastermind GT to send program change number 0 to this device. Init PCs Sequential – Initializes all presets for this device. Selecting this option will initialize all presets on the Mastermind GT to send a sequential program change number to the device. Preset #0 will send program change #0, preset #1 will send program change #1, etc. This is the default setting for a new device.
Type – Selects the type of this button.
Upd On Prst (Update on preset change) – When set to “Off”, this button only changes state when it receives a MIDI message from the device it is associated with, or when the button is pressed. When set to “On”, the button can also change state when a new preset is selected. Typically, this is always turned on, but with certain devices like the Axe-Fx it should be turned off. Tempo – When set to “On”, this button is marked as a tap tempo button. These buttons flash with the currently set tempo.
The last of the three buttons is not active when editing a Note action. System System actions are further defined by the Function parameter. The possible settings for Function, and their parameters are as follows: Page The Page function makes the Mastermind GT switch to a particular button page when this button is tapped. Page # - Selects the page number that should become visible when this button is pressed. Tuner The Tuner function turns on the tuner display when this button is selected.
