 This is the LiveLogic MIDI Foot Controller. In this video, I'm going to demonstrate how the LiveLogic can be used with any MIDI-enabled silverline amplifier straight out of the box. Using a 5-pin MIDI cable, connect the MIDI output from the LiveLogic to the MIDI input on the back of the silverline. Whilst the LiveLogic is in patch mode, it will automatically be able to switch your pre-save patches on your silverline amp. Switches 1 to 4 cycle through channels 1 to 4. Whilst switches 5 and 6, bank up and down. This allows you to save 12 presets to your silverline amp and change them in real time with the LiveLogic MIDI Foot Controller.
