Now available in 10, 16 and 22 button configurations!
The Mastermind GT is the result of years of research and development, using modern technology to create what we believe is the best MIDI foot controller ever made. Our initial prototype shown at the Winter 2011 NAMM Show drew an unprecedented amount of attention from all over the music industry: guitarists, DJs, keyboardists, producers and more. We've made many improvements over that original prototype and are now ready to deliver it to market.
By adding a display over every button, we've made it possible to have a fully configurable MIDI controller. Any button can be assigned to any function, and colors and button text are fully configurable by the user. Buttons can send multiple MIDI messages of several types, and there can be up to 16 pages of buttons so you will always have access to all of the functions your rig has available.
Add in other features such as user upgradeable firmware, USB thumb drive support and built-in support for many popular MIDI devices, and you can see why there has been so much buzz about this product.
Version 1.4 adds MIDI clock support, Global preset, quick access menus for presets, songs and pages, and the ability to send different program changes when an IA button is turned on or off. Also added support for Strymon Big Sky and Line 6 M5. Please see the RJM Forum for the full list of changes.
Version 1.4.5 is a minor bug fix release to address a few issues with global buttons, and using Mastermind GTs in remote mode with an Axe-Fx.
To update your firmware: First, back up your settings to a flash drive or computer! Download and unzip the above file. Copy the file to a USB flash drive, and remove any other .rjf files from the flash drive. Eject the drive from your computer. Insert the drive into your Mastermind GT, and power on the Mastermind GT while holding the two buttons under the main screen. Keep holding until you see "MMGT Bootloader" appear on the screen. The update should take a minute or so.
