Voodoo Lab's Ground Control Pro gives you the ultimate power to configure and reconfigure your rig with just the tap of a footswitch. Control up to eight MIDI devices, each with their own separate channel, with the Ground Control Pro and then assign the GCP's buttons for instant access to loops or processors. It's the friendliest, easiest MIDI foot controller, even allowing you to name each preset so you don't have to remember the difference between Preset 1 and Preset 6. Volume and expression pedals can plug right in for real-time control of your MIDI messages as well.
