Click-and-drag on the horizontal Level fader to adjust the send level between -∞ and +10 dB.
Click-and-drag on the Pan fader to adjust the balance of the source material going to the send
destination. Click on the Pre/Post Fader button to switch the send source to pre-fader or post-
fader. Pre-fader allows you to set a send level independent of the channel fader so that the
level is unaffected by fader position.
The send source signal is always post-inserts.
9.2.14 Sidechaining
Certain effects can accept an input from an audio source that dynamically changes the
behavior of the effect. This is called "sidechaining," and it facilitates processes such as keying,
ducking, and de-essing. Sidechaining is accomplished by using a send to route audio to a
special Sidechain input on an insert effect.
It is possible to send to the Sidechain input of any insert effect, whether or not the sidechain is
engaged in the effect. For the sidechain to work in the effect, it must be engaged in the effect.
An example of sidechaining is when a gate is triggered by a specific audio signal. In this case,
the gate will open and close dynamically in response to the audio signal coming in the
sidechain, rather than responding to the program signal on the channel where the gate is
inserted. Several of Studio One's built-in effects support sidechaining, including the
Compressor and Gate. For more information, refer to the "Built-In Effects" chapter.
9.2.15 Send to a Bus
It is possible to use a send to route audio to a Bus Channel. This is done in the same manner
that a send is used to route audio to an FX Channel, except that the Bus Channel is selected.
This can be used, among other things, for "multing"—routing a channel to multiple places—
which is a convenient way to layer sounds.
9.2.16 Copy a Send to Another Channel
Sends can be copied from channel to channel in the same way as inserts. To do this, click-and-
drag a send from one Send Device Rack to another one. This will create an identical send on
the channel.
9.2.17 Navigate and Create Effects Presets
At the top of every plug-in window is a set of standard controls. In the upper left, next to the
Activate button, are Preset controls, including a Store Preset button and a Presets window. To
view the presets for an effect, click on the Presets window and browse the pop-up list. To
select a preset, click once on the preset in the list.
