Rotary Encoder section
Rotary Encoder
Each Channel has a rotary encoder. The func­tion of the rotary encoders depends on the cur­rent mode and view.
Console Views Rotary encoders control channel pan, send level and assignments, depending on which Console view is enabled (Pan view or Sends view). If your system includes a Digide­sign PRE, mic pre level can be controlled from the rotary encoders in Console view.
Channel View Rotary encoders control plug-in, pan, send, or plug-in settings and assignments, depending on which Channel view is enabled (Pan/Send view or Insert Select view). If your system includes a Digidesign PRE, most mic pre controls can be accessed in Channel View.
Flip Mode Rotary encoders control track Volume or Send pan position when Flip mode is enabled.
Rotary Encoder LEDs
Each rotary encoder has a ring of 11 LEDs for in­dicating data values controlled by the encoder. Discrete or stepped information such as pan po­sition or frequency is shown by a single LED. Continuously variable values such as send level, gain, or filter bandwidth are shown by an ex­panding series of LEDs.
Encoder LED rings can show send level, pan po­sition, and plug-in parameter values. In Flip mode, they can show track level or Send pan po­sition.
Select When the Select/Auto switch is unlit, it is in Select mode. In this mode, encoder switches toggle plug-in parameters displayed above the corresponding encoder.
Encoder Switch
The switches under each encoder perform a va­riety of functions, depending on what is shown in the LCD displays. Functions of the encoder switch include:
• Sends Console view: Toggling Send mute or Send pre/post status
• Pan/Send Channel view: Toggling Send mute or Send pre/post status
• Parameter view: Cycling stepped plug-in parameters, setting up multi-mono plug-in operation
• Mic Pre view: If your system includes a Digidesign PRE, controlling mic pre set­tings
• Groups view: Selecting Group IDs for new groups, enabling or selecting current Groups
• Soft Keys view: Cycling preferences or per­forming actions
• Default switch: Setting parameters to their default values
• Window Configuration view: Creating, ed­iting, and recalling Window configurations
• Memory Location view: Creating, editing, and recalling Memory Locations

The Masters switch cycles temporary display of Master Fader tracks and VCA Master tracks (Pro Tools HD only) on the right side of the C|24 faders. The Masters switch flashes to indicate display of Master Faders or VCA Master tracks.
Home/Pan Flip Mode
When C|24 is in Pan Console or “Home” view, Flip mode transfers control assignments as fol­lows:
• Faders control channel pan.
• Rotary encoders control channel volume.
When an Instrument track is in MIDI mode, Flip mode transfers control assignments as follows:
• Faders control MIDI pan.
• Rotary encoders control MIDI volume.
Send Flip Mode
Flip mode transfers Send control assignments as follows:
Sends Console View
• Faders control Send level.
• Rotary encoders control Send pan.
• For stereo Sends, control of Left and Right channel pan is selected with the L/R switch in the Pan section.
• For Sends to multichannel output paths, control of Send Pan parameters is selected in the Pan section of the Channel Bar
• Encoder switches control Send Mute or Send Pre/Post status, depending on the Switch Functions setting
Flip Modes
Flip mode temporarily exchanges control assignments between the rotary encoders and the corresponding channel faders, so you can use the touch-sensitive faders to edit and
automate pan, send and plug-in parameter values.
The effect of Flip mode depends on the current view.

Plug-in Flip Mode
When C|24 is in Parameter view, Flip mode transfers the control assignments as follows:
• Faders control plug-in parameters.
• Rotary encoders are disabled.
• Encoder switches toggle/cycle through stepped parameters.

Assign Mode

You can assign Inputs, Outputs, Inserts, or Sends from C|24 using Assign mode.
When in Assign mode, an arrow (“>”) appears to the left of pathnames or plug-in names in the LCD displays to indicate the current assign­ment. The arrow disappears to when an uncon­firmed change is displayed.
When navigating in Assign mode, you can move up a level by holding the Command/Ctrl switch and pressing the encoder switch for the control that you are assigning.
Mic Pre Flip Mode
Flip mode transfers PRE control assignments to the faders and disables the encoders, as follows:
Mic Pre Console View
• Faders control PRE gain.
Mic Pre Expanded View
• Fader under “Gain” controls PRE gain.
• Fader under “Source” toggles the PRE input source.
• Fader under “Impedance” controls the Im­pedance setting.
See “Assigning Pro Tools Paths” on page 91.
You can enter Assign mode while in Flip mode. In Flip mode, move the faders (in­stead of the encoders) to scroll through lists in Assign mode.
