Mixer Window

The Mixer manages all busses that are available in a HALion instance, that is, the 32 stereo output busses plus one surround bus, the 64 slot busses, the 4 AUX busses, and a dynamic number of program and layer busses depending on the current program architecture.

Each bus can be controlled using a dedicated mixer channel, featuring functions like level, pan, mute, solo, and up to eight insert/send effects. You can specify which type of bus you want to see at a given time by using the controls on the toolbar.

Channel Strip Controls

Mute

Mutes the bus.

Solo

Mutes all other busses and lets you hear the solo bus only. You can put several channels into solo mode to hear all of them.

Level

The level fader allows you to adjust the volume of the bus. All busses allow an amplification of +12 dB.

Pan

All stereo mixer channels provide a stereo panner that allows you to define the position of the sound in the stereo field. When working with surround busses, you can insert a surround panner effect to one of the insert slots of a bus and use it to pan the stereo signals in the surround field.

The mixer channel shows a small version of the Surround Panner, which can be used to remote-control the inserted surround panner. For more detailed editing, use the Sound Editor of the Surround Panner.

Meter

The meters of a mixer channel show the output level of the bus. The number of meters depends on the number of audio channels of the bus. Stereo busses have two channel meters, surround channels have six.

Peak Level

The peak level meter indicates the highest level on the bus in dB. To reset, click the peak level.

Output

Each channel can be routed to various busses. Click the output pop-up menu and select an output.

The output busses represent the audio interface to the host application or the audio hardware. Therefore, these channels cannot be routed freely and do not have an output pop-up menu.

Note

You can route the bus of a surround slot to one of the stereo output busses. In this case, only the first two channels are connected. You can remedy this by adding a downmix effect to the surround output bus or you can reroute the slot to a surround output bus.
