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. Each page can have a completely
different button configuration – you can change which instant access buttons are shown, how many preset and instant
access buttons there are and where those buttons are located.
Pressing the
Page / IA Store button switches from one button page to the next. Once the last page is reached, pressing
the Page / IA Store button switches back to the first page. There can be up to 16 pages of buttons, but you can limit
the number of pages visible to avoid having to scroll through pages you don’t use. By default, two button pages are
available, but this can always be changed in Setup Mode.
Each preset in the Mastermind GT can also have its own “local” button page. This page takes the place of button page
16 when the preset is loaded. The local button page will be shown by default, but you can always access the other
button pages using the
Page / IA Store button.
IA Store
The other function of the Page / IA Store button is to store information to the current preset. If you hold the Page / IA
Store button for two seconds, the on/off state of all of the instant access buttons, as well as the currently selected
button page, will be stored to the currently selected preset. This allows you to have your instant access buttons turn on
(or off) automatically when you select a preset. You can also have the button page you need automatically become
visible when a preset is selected – this allows you to have the instant access buttons you need at each moment in front
of you, even when you have many pages of buttons.
IA Mode
The IA Mode button allows you to convert every button (except the IA Mode button itself) to an instant access button.
This function is also known as the “IA reveal” on other MIDI controllers. In this mode, you can have up to 21 instant
access buttons available (15 IA buttons on the Mastermind GT/16, 9 IA buttons on the Mastermind GT/10). This allows
you to switch presets to perform the more dramatic sound changes (perhaps from song to song), then tap the
IA Mode
button which allows you to fine tune by turning individual effects on and off. You can decide if all of the buttons switch
to instant access, or if some retain their functions in instant access mode.
