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.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.Features:22 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.
