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. It's popular with guitarists, DJs, keyboardists, producers and more. The Mastermind GT series is very popular with Kemper and Fractal Axe-Fx users, and we're also seeing quite a few users running it with Ableton, Logic and other DAW software.

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.

Features:

• 16 buttons, with an LCD display over every button. Any button can be set to perform any function (preset, IA, bank up/down, tap tempo, etc.) and the LCD will indicate what the button does. No more board tape!
• A large main LCD display shows the preset number, preset name and/or song name
• Standard MIDI In and Out ports
• Phantom power capability allows you to run the Mastermind GT with a single MIDI cable - no separate power supply needed
• More than one Mastermind GT can be connected together and used in multiple locations on stage
• Jacks to connect four expression pedals and four external switches allow for lots of control over connected effects processors and other MIDI devices
• Two auxilliary 9VDC power outlets for tuner, wah pedal, etc
• USB support for direct connection to a PC or Mac
• USB thumb drive input allows you to save and restore settings to a thumb drive
• Editor software for PC and Mac
• Advanced on-board editing capability which makes this controller very easy to program, even without using the editor software
• Built for the rigors of the road with high quality components throughout
