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 2
nd
Press) option. Set it to “Global”.
Setting it to “Preset” disables the global preset feature.
There is also an additional setting, “Previous”, which moves you back to the previously selected preset when you press
the currently selected preset button a second time.
Page, Preset, Song and Setlist Menus
There are special button types called “Page Menu”, “Preset Menu”, “Song Menu” and “Setlist Menu”. Pressing one of
these buttons makes the entire Mastermind GT surface a selection menu, giving you quicker access to a specific page,
preset or song. If needed,
Prev and Next buttons are displayed so you can scroll through the multiple pages of choices.
Please refer to the Edit Button menu reference for more details on how to set a button to one of these types.
Preset Number Selection
There is also a “Preset Number” button type. Pressing it will allow you to type in a preset number and recall a preset
directly. The Mastermind GT will automatically jump to the preset once you’ve typed in enough digits. For example:
typing “001” will jump to the first preset. You can also press the Done button to jump to a preset without typing all the
digits: “1”, “Done”.
On the Mastermind GT/10, there is not enough room to fit a Done button, so you’ll always need to type in the full preset
number with leading zeros.
IA Linking
Sometimes, it’s useful to have one IA button turn on another. For example, you may have buttons on multiple button
pages, each of which control the same effect. If you turn one on, you would want the others to turn on as well to reflect
the current state of your effect. If you turn on reverb on button page 1, a reverb button on button page 2 should be on
as well. This will work across all 16 button pages, including the current preset’s local button page if there is one.
To do this, turn on the “IA Link” parameter on each of the IA buttons. You also need to have the first action in each
button’s list be identical. For our reverb example, each button would have to send the same CC message turning reverb
on (or off) in order for the IA Link to work. The second and subsequent actions on each button don’t need to be the
same for the IA Link to work.
Please note that only the IA button that’s actually been pressed will send its MIDI messages. The linked IA buttons will
change their visible state to match the IA button that was pressed, but they will not send their messages.
Tap Tempo and MIDI Clock
Each button has a Tempo parameter. If this setting is turned on, tapping the button repeatedly will make it flash at the
same rate it was tapped. Tempo buttons are typically programmed to send tap tempo messages to MIDI effect
processors so that the effect will also be locked to the same tempo.
When the current tempo changes, the tempo rate is displayed on any tempo buttons, shown in beats per minute. It is
also briefly shown on the main LCD display.
For more advanced tempo support, the Mastermind GT supports MIDI clock as a master or slave. With MIDI clock, you
can synchronize multiple devices to the same tempo. To enable MIDI clock support, go to the
MIDI Settings menu. The
MIDI Clock parameter can be set to “None” (the default), “Master” or “Slave”.
