The Axe-Fx III Mark II stores a whopping 1024 presets, each one equivalent to an entire rig, whether as simple as just an amp, or as complex as a massive pedal-board and multi-amp rack system.
Fractal Audio's “Channel” concept is a revolution in functionality. Each effect block has up to four channels with each channel containing a unique set of parameter values. Channel switching is instantaneous and seamless and can be done manually (via a foot controller, for example) or automatically when changing scenes. Channels can also be switched via MIDI for applications requiring automation.
Channels provide quick, easy parameter switching without the unwanted side-effects of preset changes (due to grid reordering). Set the Amp block so that Channel A is a “Deluxe Verb” model, Channel B is a “Plexi”, Channel C is a “Recto” and Channel D is “FAS Modern”. Then change channels instantly at the touch of a button.
Eight Scenes within each preset store the bypass state and channel for each block. Program each scene to be a different combination of channels and change the channel and state of multiple blocks rapidly at the touch of a button. Like channels, scenes can be switched via MIDI for automation applications.
By using channels and scenes a single preset can be used for an entire song, an entire set or even the entire show. No tap dancing required.
