Installation and Setup
The basic assumption of this manual concerning using the SAC-2K/2.2 in Logic Control mode is that you have already
connected, set up and installed the SAC-2K or SAC 2.2. You can use either the MIDI or the USB connection, the
functionality is the same. Once the SAC is connected to your system, Logic Audio Platinum (version 5.1 or better) will
“recognize” the SAC automatically as a Logic Control and activate the SAC’s LGC operation mode. When you start up
Logic Audio it scans all active MIDI Ports for hardware controllers. This Scan Function sends a brief Sysex message, the
Logic Control responds to if connected. Once the SAC receives this Sysex message, it automatically switches to Logic
Control Mode and waits for your input.
To verify the installataion or to edit the configuration parameters proceed as follows:
Select “Options” > “Control Surfaces” > “Setup…”
This will open up the Logic Control setup window. If you don’t see an icon of the Logic Control in this window, Logic
for some reason has not recognized the SAC. In this case, check your connections between SAC and computer once
more,switchthe LGC mode manually in the system menu of the SAC and restart Logic. By now you should definitely see
the following display in the setup window:

7
Click on the Logic Control icon. On the left side of the setup window you should now see the parameters of the selected
control surface.
In the section “Special Parameters” you should definitely deactivate the option “Touchless movable faders”. Use of this
functionwithequipment with reliable touch sensitivity technology is not advisable, because in this mode fader movement
is also used to recognize activation of the fader. Such “intelligence” cannot distinguish accurately between movement
generated by manual movement of the fader and motor movement. This can result in this function becoming the source
of potential problems during the recording of automation data.
Theotherselectionoptions,whichappearfurtherdownontheparameterlist,arenotrelevantforthegeneralfunctionality
of the SAC and we will skip further detailed explanations at this time. More important are the settings in the dialog box
“Preferrences…” (“Options” > “Control Surfaces” > “Preferrences…”), which we will pay attention to next.
Relativecontrol resolution
Logic’sdefaultvalueforthis parameter is 128. This means that an encoder will have a resolution of 128 steps per rotation,
in order for the complete value range to be covered in a full 360 degree revolution. This isn’t the case with the Logic
Control or with the SAC. Adjust this parameter to a considerably lower value, so you can cover bigger range of values
with one encoder revolution. A lower value means that the intervals between the edited parameter’s value ecome
coarser.However, you can still make fine parameter adjustments, by pressing the [Alt] Button while rotating the encoder.
The encoders of the SAC have 24 values per rotation. You should set this parameter to a value between 24 and 48, to
enable you to cover wide value ranges easily.
Usemultiplecontrolsper parameter
Set this option to a value of 1. Due to the SAC’s layout there is no benefit when this option is activated.
Showlong names whileediting:
Disable both the “Parameter Name” and “Parameter value” options. Because the sizes of the displays differ between the
Logic Control and the SAC, names and values can be displayed incorrectly if elongated information is used. The SAC
can display considerably more characters and its control elements are located further apart. The SAC is programmed to

8
display blank spaces for a correct replication of Track Names between the individual channels. If these options are
checked it is possible that long parameter names can be separated in pieces.
Displayduration(s)
This parameter determines how long the alternate longer version of the parameter name is shown in the display, after
releasing the relevant encoder. If the long paramter names preference is switched off, this parameter has no function.

Volumeandotherparamters
The above mentioned parameters can be adjusted to your personal preference. Displaying units usually results in the
expense of length of other info, i.e. parameter name or track name
MaximumMIDIbandwith(%).
With this paramter you are able to increase or decrease data throughput. If you notice performance fluctuations during
work with the SAC you can decrease the value. We never encountered such problems with our test systems. Of course
decreasing this parameter also causes a decrease in automation accuracy.With the SAC, this parameter can only change
the data throughput from Logic to the SAC. However, it is also possible to change the datathroughput in the SAC’s
System menu. You will find more details in the SAC 2.2 manual under System menu settings.
Buttonassignement inLogicControlmode
In Logic Control mode, the SAC’s button assignment does not conform with the labeling information printed on the
surface. You will find a graphic of the actual button assignments on pages 2 and 3 of this manual. (you can print the two
pages for referrence)
You can find the button assignment used in the following charts. We are currently producing special templates, which
will allow comfortable working with these button assignments, similar to earlier templates we produced for Digital
Performer and Pro Tools. We will be happy to send you these templates free of charge upon request. For the time being,
you can also write on the backs of the included templates, for temporary ease of operation.
JogWheelButtons
This group of buttons is set up in a circle around the Jog Wheel. In the left column of the charts you can see the original
function inscription of the SAC and in the right column the according function corresponding to Logic Audio.

The assignment of the transport buttons is as labeled on the SAC.

SACMixerModeButtons
Located Between the two fader groups of the SAC are the Mixer Mode buttons. In the following chart you can see the
LGCassignments.
TheSoftwareNavigationButtons
Just above the Locator Display of the SAC are the Software Navigation buttons. The [Num] key of the SAC is of
particular importance. It is used for toggling the assignments of the remaining SAC Software Navigation buttons. We
will use the name SAC Option for this button in the following chapters. When the [SAC Option] button is pushed it
lights up and the third display momentarily shows the current status of the four functions which are assigned to the
upper first four buttons. You will find the assignments of the Software Navigation buttons in the following two charts.

TheMaster Select Button
The [Master Select] button above the master fader has been assigned the [Global view] button function of the Logic
Control.
TheChannel Strip Buttons
The Channel Strip buttons of the SAC are used to activate the various automation modes of Logic Audio. The one
exception is the [Instrument] Channel Strip button. The Instrument button allows you to call up the integrated synth
editors of the SAC, just like in other SAC modes. When in LGC mode, double-click the [Instrument] button to call up the
Instrument editor section.
