Customizable Control of Your MIDI Rig

The RJM Music Mastermind GT/22 22-button MIDI foot controller is a powerful way to control every aspect of your MIDI-based rig.

The layout of the parameters assigned to each button can be edited for what works best for you. And the GT/22 carries enough I/O for expression pedals, USB connectivity to your computer, 9-volt power outputs, and more. You'll simplify your onstage switching with this Mastermind GT/22.

RJM Mastermind GT/22 MIDI Foot Controller at a Glance:
  • 22 multicolor, backlit LCD screens
  • Choose the layout that works for you
  • Plenty of I/O for even more control
22 multicolor, backlit LCD screens

The 22 multicolored, backlit LCD screens onboard the Mastermind GT/22 are customizable, letting you choose what parameters they control. Using color coordination, you'll instantly know if the button will recall a preset, if it's a tap tempo, or if it engages a particular effect. The LCDs were chosen because they can easily be seen in any lighting, including bright sun. And the text across the screen is bold when that particular button has been selected.

Choose the layout that works for you

You have total control of the layout on the Mastermind GT/22. Any of the 22 buttons can be set to control program changes, bank up/down, individual effect control, and more. This allows you to organize the 22 buttons however you need. You'll have access to 16 pages of buttons, each being able to control up to 16 connected devices, ensuring plenty of space for all of your commands. And all of the programming can be done from the front panel, making setup a breeze.

Plenty of I/O for even more control

The Mastermind GT/22 carries enough I/O to offer up to 768 presets. The MIDI ports allow the buttons to send 20 messages instantly. Two external switch ports and four expression pedal inputs give you control over modulation rate, volume, wah simulation, or any other MIDI-controllable parameter. Two 9-volt power outputs allow you to power additional accessories on your pedalboard. And two USB ports allow for connection to your computer as a MIDI device and to a flash drive for saving your settings elsewhere.

Game Changer!

For years and years, I had only imagined that something like this could exist. As a solo performer who uses multiple instruments, guitar effects, and parallel loops, I was running into limitations with conventional effects pedals and looping systems, and in addition to many of my production needs, I truly needed a way to "End the Pedal Tap Dance" as the good folks at RJM say. This unit's behavior is completely software-defined, giving the user the power to configure page after page of completely custom appearance and behavior. The bright LED displays make it easy to label and understand the state of any button on any page- down to the velocity of the bits and the brightness of the displays. This product completely changes the game for anyone who is ready to take their rig to the next level, integrate the latest technology, and get ahead of the pack. For me, that meant my "one man band" move to Ableton Live where I use the GT22 to control all of my software-defined guitar effects (using Native Instruments Guitar Rig), controlling all of my looping parameters (i.e. Rec/Play, Stop, Undo, Clear, etc) for 5 separate loop banks, and have even added in DJ-style effects such as filter sweeps and beat repeats. I can even use the GT22 with Ableton Live to control things like lighting scenes- with plenty of real estate left to spare. If you're looking to build a monster looper like Ed Sheeran's "Chewie Monsta", this is a great place to start- and you can actually do much more with the GT22! The support on this product is also 2nd to none. The owner of the company takes great pride in seeing his users become successful, and has often stepped in directly to help me in my use of the product. I highly recommend the Mastermind GT22.
