Configuring Simian's Mixers

Often Simian users need a way to automatically control audio signals as they "pass through" the automation system. Many professional grade audio cards will allow you to route your audio directly from an input to an output. In audio card parlance, we call this pass-through. If your audio card supports pass-through, and you can control the volume of the input via software, then Simian can effectively use your audio card like a mixing board.

To do this, you'll want to open the Mixer Panel by clicking on the Mixer button in the lower right-hand corner of the Simian interface (see Figure 1).

Simian has 16 on-screen mixers. You can assign up to four individual audio devices to each mixer (most consumer grade cards have one audio device, while professional cards may have many). You can then use the mixer slider on the Mixers Panel to directly control those devices. To assign an audio device to a mixer, just click the button under the slider. Youíll see the dialog box shown in Figure 2.

Now, letís look at these options individually

Friendly Name:

You can call the mixer anything that you want up to 5 characters. Whatever you type in this text box will display on the button under the mixer in the Mixers Panel.


Letís say that you have an AudioScience 6012 card and an Audio Science 5111 card installed in your computer. This option would allow you to select the individual card that you want to control with this mixer.


Your sound card will have a number of different lines (volume controls) available to control different devices, inputs, or outputs. You can select any of the lines here. Generally, only input lines are assigned to Simianís mixers, as the play device mixers are automatically assigned by Simian.


Audio devices often have more than one fader. This drop-down allows you to select which of the faders that you want to control on an individual device.

Selected Controls:

Once you have selected your fader, just click the "+" button next to one of the Selected Controls lines to add your configuration to the list. You can control up to four faders with each mixer by adding them to the list. This is handy for multiple-device audio cards.

AutoMute controls during audio file playback:

If you want to automatically mute this mixer whenever the playback devices become active, you can select this option.

NOTE: A common misunderstanding of the Mixer Setup window is when re-opening the Mixer Settings window for a mixer that has already been configured. You will notice that all the fields have defaulted back to the top option on each dropdown. This is normal behavior since the settings previously made are stored in the selected controls boxes.


Now that we know how to configure the Mixers, we can easily assign a mixer to the input volume fader on our audio card. With this done, we can then use the MIXVOLUME and MIXFADE macros to automate what our mixer is doing.
