Routing example

Audio Interface FocusRite Saffire Pro 40
Input Source Windows applications, stereo format
Output 4 analog channels
Method Internal loop back

Goal

We want to use Ekio to filter the stereo stream emitted by Windows applications. Ekio transforms the input stream into 4 analog channels, which are sent to four amplifiers.

Configuration

The proposed solution is illustrated bellow:

We create the following links:

Link 1:

PC applications use the classical Windows audio drivers (WDM, DirectSound, etc). The sounds are sent on 2 channels.

Link 2:

In order to direct the stereo signal received from Windows to ASIO inputs, we use the loop back channels of the card. The Saffire Pro40 router automatically sends these channels to ASIO IN. So we connect:

DAW1 ➜ Loopback 1

DAW2 ➜ Loopback 2

Link 3:

Within Ekio, we start by choosing the Saffire sound card.

Then we select the entries of interest. The list of inputs contains all the physical inputs and the Loop back channels. We choose the Loop back entries 1 and 2, which is equivalent to channels 19 and 20.

Link 4:

For outputs, 20 DAW channels are available. The WDM drivers occupy the first channels. If Windows is configured for 2.0 output, channels DAW1 and DAW2 are busy. If Windows is configured for 5.1 output, channels DAW1 to DAW6 are busy. If Windows is configured for 7.1 output, channels DAW1 to DAW8 are busy.

We need to avoid the first channels and we configure Ekio so that the outputs are on channels DAW9, DAW10, DAW11 and DAW12.

Note

Do not take in consideration the names used for the output channels. They copy the names of the physical outputs and do not correspond to the current routing.

Link 5:

In MixControl, we connect the physical outputs:

DAW9 ➜ Monitor Output 1

DAW10 ➜ Monitor Output 2

DAW11 ➜ Line Output 3

DAW12 ➜ Line Output 4

Link 6:

Analog outputs 1 to 4 are connected to four amplification channels.
