IA Off Color – Sets the color of this button when the button is off and the controller is in IA mode. This option is not
available for IA buttons.
Group - This allows IA buttons to be grouped, where only one button in the group is allowed to be on at a time.
Pressing a button in the group turns that button on, and also turns all of the other buttons in the group off. This is
typically used for things like amp channel selection, where the amp may have 3 or 4 channels but can only have one
turned on at a time. There are 8 groups, and each group is independent of the others. All buttons with the same group
number will be treated as the same group, regardless of which page the buttons are on.
Button Actions (x) – This button displays the number of Actions it currently has assigned to it. Pressing the button
brings up the list of Actions that are assigned to this button. Each button may have up to 20 Actions assigned to it. Each
action is typically a continuous controller message sent to control a function on a device, but it could also be another
type of MIDI message or a system action that controls the Mastermind GT itself.
In the Button Actions menu, pressing one of the Action buttons or the Add Action button brings up the Action Edit
menu.
IA Cycle – Turning this on makes this IA button cycle between multiple states. Instead of just having on and off states,
the button can have up to four different states, and pressing the button will cycle through each state.
IA Link – When this parameter is turned on, this button will be linked to other IA buttons that have the same first action
in their action list. Turning one IA button on will turn all other linked buttons on, turning one IA button off will turn the
linked buttons off. Please refer to the IA Linking section for more details.
CC Link – When this parameter is turned on, it allows this button to be controlled by incoming CC messages. Please see
the External MIDI Control section of this manual for more information.
SndOnPrst (Send on preset change) – When set to “On”, this button will send its messages every time the preset
changes. When set to “Off”, this button will only send its messages when it is pressed.
UpdOnPrst (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. If UpdOnPrst is also turned on, this button will flash in time with the internal tempo clock. If UpdOnPrst is
turned off, this button will only flash when instructed by the connected device.
Momentary – When set to “On”, this button is momentary – it turns on when pressed and turns off when released.
When set to “Off”, this button is a normal (push on / push off) button.
OnMsgOnly - When set to “On”, this button will only send messages when it is turned on by a preset. When a preset
turns this button off, this button will not send any messages. This setting does not affect what happens when the user
actually presses the button.
Step [1..4] Name - When IA Cycle is turned on, these parameters set the name that will be shown for each of the four
steps the button can cycle through.
Step [1..4] Color - When IA Cycle is turned on, these parameters set the color that will be shown for each of the four
steps the button can cycle through.
