Plugins are software units (LV2 specifically) which provide some type of function on a Pedalboard. The function might be audio processing (eg. “effects”), audio generation (eg. “synths”), MIDI manipulation, etc. The set of plugins for the currently active Pedalboard are shown on the main home page of the LCD.
A Pedalboard is a combination of Plugins and cable routings, together forming a virtual music equipment setup. There is always one pedalboard active on the device. The current Pedalboard name is shown at the top of the main home page of the LCD and can be changed by navigating to that name, then clicking.
A Bank is a collection of pedalboards used as a means of organizing them for easy access. A single pedalboard can exist in multiple banks. Deleting a Bank does not delete the pedalboards inside it. Banks are useful for focusing on a subset of pedalboards instead of the entire set of pedalboards on the device. Since the pedalboards within a Bank are ordered, usage of Banks makes scrolling thru pedalboards in a user defined order easier, as might be desirable for setting up a performance setlist. The current Bank can be changed via the System menu. The default mode is for no Bank to be active, meaning that all pedalboards on the device will be shown during pedalboard selection.
A Snapshot stores the state of all plugin parameters on a pedalboard. Each Snapshot is specific to the pedalboard it was created for. Each Pedalboard has a Default Snapshot. Snapshots can be used to specify different scenes, parts of a song (verse, chorus, bridge, etc.) where the set of plugins don't change, but the settings do change between Snapshots. The current Snapshot name is shown at the top of the main home page of the LCD and can be changed by navigating to that name, then clicking.
The pi-Stomp LCD screen shows the state of system and the current pedalboard. The Navigation encoder knob is used to interact with the LCD (kindof like a computer mouse).
