This section outlines the assignment of the Radikal Technologies SAC-2K interface elements to Logic functions.
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. |
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. |
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).
| |
Snd/Ins | Switches the four Snd/Ins (1 to 4) buttons between Send and Insert modes.
| |
Snd/Ins 1 to 4 |
| |
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:
| |
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. |
The following table outlines the software navigation controls and their assignments:
