Radikal Technologies SAC-2K: Assignment Overview

This section outlines the assignment of the Radikal Technologies SAC-2K interface elements to Logic functions.

Radikal Technologies SAC-2K: LCDs and Encoders

The following table outlines the LCDs and encoder controls, and their assignments:

Control	Assignment
Left and middle LCDs	Upper row displays the channel number when in a Mixer (multichannel) view mode. The parameter name is shown when in a (single) Channel view mode. Lower row shows the parameter value of the corresponding encoder (the one directly below the display). Level meters are shown to the right.
Right LCD	Upper row displays the name of the parameter being edited with the corresponding encoder (the one below). Lower row displays the parameter value (assigned to the encoder below the display). The Master Output level meter is displayed at the far right.
Encoders	Edit the corresponding parameter shown in the LCD.
Encoder push buttons	Parameters with two values (On/Off): Switches between the two values. Parameters that access items (plug-in selection, for example): Confirms preselection. At other times, sets the parameter to its default value.

Radikal Technologies SAC-2K: Channel Strips

The following table outlines the channel strip controls and their assignments:

Note: A modifier button, such as SHIFT, below a button description indicates that the button has an alternate function or use while the modifier is held down.

Control	Modifier	Assignment
Mute/Solo		Switches Mute/Solo 1 to 8 buttons between Mute and Solo modes. LED off: Mute/Solo buttons switch Mute state on/off. LED on: Mute/Solo buttons switch Solo state on/off. LED flashes: Mute/Solo buttons switch Record Enable state on/off.
	SHIFT	Sets Mute/Solo buttons to Record Enable mode.
Mute/Solo 1 to 8		Mute/Solo LED off: Enables/disables Mute; LED displays Mute status. Mute/Solo LED on: Enables/disables Solo; LED displays Solo status. Mute/Solo LED flashing: Enables/disables Record Enable; LED displays Record Enable (armed/disarmed) status.
SELECT 1 to 8 buttons		Selects channel. Exception: In Group mode, these buttons define group membership of the channel.
Master Select button		Switches Flip mode between Off and Duplicate.
Faders 1 to 8		Controls volume, or duplicates the parameter assigned to the encoder above (if Flip mode is enabled).
Master Fader		Controls the Master Level fader if it exists; if not, controls Output 1–2 level.
EQ button		Inserts a Channel EQ in the channel if no Channel or Linear Phase EQ is present.

Radikal Technologies SAC-2K: Mixer View Mode Section

The following table outlines the Mixer view mode controls and their assignments:

Note: A modifier button, such as SHIFT, below a button description indicates that the button has an alternate function or use while the modifier is held down.

Control	Modifier	Assignment
Pan		Switches to Mixer view (multichannel) pan editing.Encoders 9 to 12 edit Pan/Angle, Diversity, LFE, and Spread of selected channel (in Surround mode).
High, HiMid, LowMid, Low		Switches to Mixer view (multichannel) gain editing of a certain EQ band. Encoders 9 to 12 edit Frequency, Gain, Q factor, and On/Off for the selected channel. Pressing and releasing the button chooses a specific EQ band. While held down, you can use Encoder 9 to choose the EQ band that you want to edit (bands 1 to 8). The button’s LED is lit when in Mixer view Gain Editing mode (of the selected channel EQ band). Low: Band 3 (first parametric EQ band) LowMid: Band 4 (second parametric EQ band) HiMid: Band 5 (third parametric EQ band) High: Band 6 (fourth parametric EQ band)
Snd/Ins		Switches the four Snd/Ins (1 to 4) buttons between Send and Insert modes. LED off: Send mode LED on: Insert mode
Snd/Ins 1 to 4		If in Send mode, switches to Mixer view (multichannel) send level editing of Sends 1 to 4. Encoders 9 to 12 edit Destination, Level, Pre/Post, and Mute of the selected channel. You must confirm the send destination by pushing the Encoder 9 button. While held down, use Encoder 9 to select the desired Send number (1 to 8). The button’s LED is lit when in Mixer view Send Level Editing mode (of the selected channel Send slot). If in Insert mode, switches to Mixer view plug-in selection for Inserts 1 to 4. Plug-in selection is confirmed by pressing the encoder’s push button. While held down, use Encoder 9 to choose the desired Insert slot number (1 to 15). The button’s LED is lit when in Plug-in Selection mode (of the corresponding channel Insert slot).
Audio		Switches to Mixer view, and displays audio channels.
	SHIFT	Switches to Mixer view.
MIDI		Switches to Mixer view, and displays MIDI channel strips.
	SHIFT	Switches to Arrange (Track) view, and displays the channel strips of all tracks used in the Arrange window.
Input		Switches to Mixer view, and displays input channels.
	SHIFT	Switches to Mixer view, and displays the master and output channels.
Inst		Switches to Mixer view, and displays (software) instrument channels.
	SHIFT	Switches to Mixer view, and displays aux channels.
Bus		Switches to Mixer view, and displays bus channels.
	SHIFT	Switches to Single view.
Group		Switches to Group editing mode: Encoder 1 to 10 push buttons edit a group property. (The property is shown in the LCD’s lower line.) Encoder 11 scrolls through group properties. Encoder 12 selects a group to edit. Its name is displayed in the lower LCD line, above Encoder 12. Select buttons 1 to 8 activate/deactivate group membership of the channel.
1 to 8		Shifts the fader bank (a group of channels or parameters) to the left by one bank.
9 to 16		Shifts the fader bank to the right by one bank.
17 to 24		Shifts the fader bank to the left by one channel.
25 to 32		Shifts the fader bank to the right by one channel.
