The Foldback strip
The Foldback strip

The Foldback section is an optional feature that provides stage monitoring mixes. Many times the main mix is used for this purpose is a setup with only the control room. However, for a separate studio and multiple monitor mixes for in ear use, a separate set of foldback buses provides that flexability.

The Foldback bus was added in Ardour Version 6.0.

These foldback buses may be mono for a stage monitor wedge or stereo to allow inear or headphones to have different mixes for each ear, such as one's self in one ear and the rest of the music in the other.

A foldback mixer strip can be created on the fly by creating a Foldback Bus in the same manner as any other bus is created, from the Track > Add Track, Bus or VCA Window. Once at least one Foldback bus has been created, the Foldback strip will appear in the mixer window

The View > Mixer: Show Foldback Strip checkbox will determine if the Foldback strip is visible. The Foldback strip appears Just to the left of the Master strip in the Mixer window. It comprises:

  1. Previous and Next buttons

Previous and Next

The Previous button shows the previous Foldback bus in the Foldback strip. The Next button shows the next Foldback strip. The button will be disabled if there are no nore Foldback buses in that direction.

Hide

The hide button hides the Foldback strip when not being adjusted. The Foldback strip can be shown again from the main menu View > Mixer: Show Foldback Strip item.

Name button

The name button shows the name of the current Foldback bus. It has two menus the Foldback bus selection menu, activated with a mouse button 1 click and the context menu, activated with a mouse button 3 click. The context menu has these items in it:

Invert Buttons

The invert buttons (one for each channel) invert the audio signal. This may be useful in some situations for controlling feedback. However, proper microphone and monitor placement or the use of head phones or in ear monitoring will be more effective.

Show Sends

Show sends allows the send levels and pan to be controlled from the originating track by using the main fader for the track. The fader and pan controls will change color to indicate this mode and the show sends button will flash to indicate this mode. Changing the current Foldback bus will disable this mode.

The Send Box

The send box shows controls for each send. There is a context menu available by clicking mouse button 3 anywhere in the send box.

The Send Control Block

The Foldback send

There is a send control block for every send to the current Foldback bus. The Send control block features three controls:

The button LED can be clicked to enable or disable that send, the button context menu is similar to the send box above but only for this send. It also has a remove option to remove this send from the current foldback mix.

The Pan Control

This is just like every other track or bus strip and works the same way.

The Processor Box

This processor box is the same as on the other tracks and buses and allows for adding things like reverb to the foldback mix without writing it to the track. It would also be possible to add in sound from a reverb bus instead.

The Listen Button

This is only available in PFL or AFL mode as it uses the same code as the solo on other tracks and buses. It allows the control room monitor or headphones to hear what the performer will hear in their monitor.

The Foldback Level Knob

This controls the output level being sent to the stage monitor.

The Output Port Selector

This is similar to the output selectors on the tracks and buses. It differs in only a few ways. First it is never automatically connected. A Foldback bus is always meant to be directly connected to an output device and never to master or the monitor bus. The choices shown Therefore reflect this.

The Comment Button

Just like the track and bus comment button, this allows opening a window to type in notes about the current foldback bus for future reference.
