The Nova System has two positions. First, there is the preset mode, with which you can easily browse through your presets to find the ideal sound for you. The second position is Pedal mode, with this position you get full control over your effect as if in one large effect pedal. In Pedal mode you can still access your presets, but you quickly gain more control over your sound and you can easily set your presets.
You can add the Switch-3 footswitch to the Nova System for easier access to multiple presets. You can also connect an expression pedal to make your effects even more dynamic and with the tap tempo function you can align your effects with your songs. The Nova System also has MIDI connections to control your settings via a MIDI controller.
