The Ground Control is a fully programmable MIDI foot-controller. It will control eight effects at once, as well as our System Mix Plus Guitar Audio Mixer and up to four GCX Guitar Audio Switchers. All without complex MIDI mapping. And with all its power and flexibility, the Ground Control is still unbelievably easy to program and use.You can create up to 100 presets (360 with optional memory). You can assign six buttons for instant access of GCX loops and processor effects, or even to start and stop a sequencer. And it's the only reasonably priced foot-controller that lets you name your presets on a big, bright alphanumeric display. Get more from your MIDI effects. Volume pedals can be used as MIDI expression controllers for real time control over parameters like delay times, mix levels and Leslie speed. Its ease of use, versatility and reliability have made the Ground Control the first choice for thousands of working musicians since 1991.
