Interfacing Styles; Physical Controls; Touch Display - Calrec SUMMA User Manual

INTERFACING STYLES

Interfacing with Summa is simple and the touch display will be familiar from using consumer technologies such as
smartphones and tablet PCs.
Aspects of the interface will be referred to throughout this manual but this section should give you a good starting point
from where you can start exploring Summa's intuitive interface for yourself.

Physical Controls

Faders
• Faders are used to control signal levels, either by having paths attached for direct control or as VCA master
faders for controlling the overall level of a range of paths.
Buttons
• All buttons on the Summa surface are labelled and LED back-lit to indicate their 'on' statuses. Buttons can either be
momentary (they trigger the function until you release them), latching (switch on or off each time they are pressed) or
auto (they latch if you tap them or act as momentary buttons if you hold them).
Rotary controls
• All physical rotary controls on the Summa surface are continuous—they have no stopping point at either extreme.
This allows the surface to be fully flexible, as all physical controls are able to control a wide range of functions within
one project.
• When a rotary control is attached to a function or parameter, the function name and options are displayed,
either on the touch display, or in the smaller fader displays.
• Once a function's extreme—either lower or higher—is reached its value will stop updating when the rotary is turned.
When a rotary is controlling a level value or a value which has a default setting, press and hold the rotary control for a
short time to return to the default value.

Touch Display

Summa's touch display uses the same general interfacing styles as a smartphone or tablet computer. Below is a rundown
or the main gestures that you will use:
Tap
• Buttons, switches, selection fields and table column labels (for ordering purposes) can all be accessed with a short
light tap.
Two Finger Tap
• Tapping with two fingers can reset settings to their default level. For example, within the fader processing tab, the
fader can be set to zero by tapping on the fader space with two fingers.
Drag
• To turn a rotary control up or down, simply drag it vertically up/right to turn it up, or down/left to turn it down.
