'Query' mode allows you to interrogate a particular path and see what other paths are routed to or from it. This is easily accessed from the Q button above the fader on the relevant channel strip.
Query mode employs all of the Fader Tiles apart from the one which contains the 'Queried' path. The Query can be 'compressed' to show only the paths turned on to the Queried path; giving a concentrated view of the paths of interest. In this mode, if there are more paths routed to the Queried path than can fit on the available tiles, additional banks will be created which are accessed using each Fader Tile's Call buttons in the usual way. Paths of the same type will be grouped together, generally in their own Bank (where two path types cannot fit into one Tile). If there are more paths than can fit into the available banks, additional layers will be created.

Alternatively, Query can be 'expanded', meaning the layers and banks you configured earlier remain on the surface. This keeps each path where you expect to find it. The Q button of paths contributing or sourcing from the Queried path will light; green if they are an input to the Queried path, red if they are an output from the Queried path.

The Q button of the queried path will flash to indicate that it is active (green if in compressed mode, purple if in expanded mode). The Layer and Bank Label Screens will also indicate Query mode by displaying light text on a dark background.

Press the Q button again to cancel Query mode and return the Fader Tiles to their previous assignment.

It is also possible to Query from the Focus and Main Faders by pressing their associated Q button. In these instances, all Fader Tiles will change to show the source/destination paths for the Queried channel.

Once a path has been Queried, controls for that path may be optionally assigned to the Quick Control encoders or channel strip faders. For monitor mixing, selecting Aux Queries to display on faders provides a fast way to access mix sends on faders, simply by Querying the Aux bus of interest (in this case each Quick Control encoder becomes the Pan control to that Aux mix, if it's a stereo Aux and Follow Pan has been disabled for that Aux; see Auxes for details). Conversely, one might Query an Input Channel and display sends on Quick Control encoders, thereby leaving the faders as the main Channel fader controls but maintaining quick access to sends via the encoders. Each path type can be configured independently; refer to the Options section.
Note: VCA faders will not be flipped and will continue to operate as normal when Querying in Faders mode.

Query Assign

Query Assign mode can be used to quickly assign paths to the Queried path. Press & hold the Q button to enter assign mode for that path. Now use the Select buttons of other paths to turn them on or off to the Queried path. It's also possible to select a range of paths by holding down the Select button of the first path then pressing the last path's Select button. All paths on the Fader Tile(s) between these two will be selected.
Press the Queried path's Q button again to exit assign mode.
While in Query Assign mode, the Quick Controls and faders will adopt the standard Query mode configured for the Queried path.
