## An Intro to Snapshots
You can create up to six snapshots for any given preset. A snapshot differs from a preset in that
{% include pageIcon.html %}
- Switching betwen snapshots does not reload the plugins you are using. Snapshots contain only control values.
- Because effects are not reloaded, you won't get discontinuities in the output of effects with long tails (like reverb effects, for example).
- Loading a snapshot is much faster than loading a preset, because new plugins don't have to be created.
- You can configure PiPedal to switch between snapshots in response to MIDI messages from a MIDI footcontroller or other device.`
Snapshots are useful if you have a USB or MIDI footswitch controller. You can easily configure PiPedal to switch between snapshots when you step on a switch on your footswitch controller. You can configure PiPedal to switch between snapshots when you step on buttons on your footswitch controller. To configure MIDI bindings for snapshots, select <b><i>Settings</i></b> from the main menu, and tap on <b><i>System MIDI bindings</i></b>.

But snapshots are equally useful when you are using PiPedal's <b><i>Performance View</i></b>. To access the <b><i>Performance View</i></b> click on the <b><i>Performance View</i></b> menu item in the main PiPedal menu.

Note how PiPedal has been configured to use <i>banks</i> as containers for songs in a set list. Each song in the setlist gets its own preset; and then snapshots are used to change controls for the preset being used in each song. As an example, the only difference between <i>Chorus</i> and <i>Chorus + Phaser</i> snaphots is whether the Phaser plugin is bypassed or not. You are of course, free to arrange your own banks and presets any way you want. But if you have a complex repertoire of songs that you play regularly, this is a good way to arrange your preset: setlists go into banks; songs go into presets; and then you use snapshots to switch between settings used in the same song.
#### Accessing Snapshots in the PiPedal User Interface.
You can create, modify, and select snapshots in two places in the PiPedal user interface.
The first is via the <b><i>Snapshot</i></b> icon button in the middle row of controls in the main page of pipedal. It's the button that looks like a camera. The second is via the <b><i>Performance View</i><b>, which is accessible via the <b><i>Performance View</i></b> menu entry in the main PiPedal menu.

It's easier to create an initial set of snapshots from the main PiPedal page. You edit the current controls of the current preset, and you can then save current control values to a snapshot by first pressing the <b><i>Snapshots</i><b> (the camera icon), and then pressing the <b><i>Save</i></b> button for a particular snapshot in the popup dialog.

On the other hand, you may find it easier to edit an existing set of snapshots from the <b><i>Performance View</i><b>. When you click the <b><i>Edit</i></b> button for a particular snapshot, PiPedal displays the <b><i>Snapshot Editor</i></b> which allows you to edit the control values for that snapshot directly.
