Intro to signal flow in Logic Pro for iPad
While you are working in the Mixer, you can insert plug-ins directly on channel strips, so that the signal on each channel strip is routed directly through its plug-ins; or you can route the audio from multiple channel strips to an aux channel strip with effect plug-ins and use the same effects on multiple channel strips.
Route audio via insert effects
When you insert an effect plug-in directly on a channel strip, it is called an insert effect. The channel strip’s entire signal is processed by the effect plug-in. This behavior is suitable for equalizers or dynamic effects such as compressors. If you have enough processing capacity, you can use up to 15 insert effects on each channel strip.
When multiple effect plug-ins are inserted on a channel strip, they are said to be routed in series. When routed in series, the output of one effect is added to the incoming signal and becomes the input of the next effect in the chain. The image below illustrates this process.
Route audio via send effects
When you route part of the signal from multiple channel strips via a send to an aux channel strip, you use send effects on the aux channel strip to alter the signal from the originating channel strips. When you create a send, you split the channel strip’s signal. The channel strip’s main signal continues to the chosen output, while the other part of the signal is routed on a parallel path via a bus to an aux channel strip. You control the amount of signal that is sent via the bus using the Send Level knob. This is called routing in parallel. You can route the signal back into the main signal flow at a later point, or you can output the signal from the aux channel strip to another destination.
The primary advantage of parallel routing using sends over series routing using inserts is efficiency: the signals from multiple channel strips can be processed by the same effects, which saves both processing power and time compared to inserting the same effect into multiple channel strips. Additionally, you can quickly switch between wet and dry versions of all channel strips that are sent to an aux channel strip by simply muting the aux channel strip (or turning off the effects on it), and completely change the effects configuration for multiple channel strips by choosing different effects for the aux channel strip.
The following image illustrates channel strips routed to an aux channel strip via sends—with reverb and EQ effects assigned to the aux channel strip.
The channel strip signal is split and routed via a send (Bus 1) from three channel strips to an aux channel strip with two inserted effects. You can create up to 12 sends on each audio, instrument, or aux channel strip.
You configure where in the channel strip the send occurs, and you set the destination for the parallel routing of the send in the Sends window. There are three options for where the send can occur in the signal flow:
Post Pan: The signal is sent after the fader and the Pan knob; the send signal is affected by adjustments to both channel strip volume and pan adjustments.
Post Fader: The signal is sent after the fader but before the Pan knob; the send signal is affected by volume adjustments but not pan adjustments.
Pre Fader: The signal is sent before the fader and Pan knob; the send signal is affected by neither volume nor pan adjustments.
You can both insert effects on channel strips and use sends with aux channel strips in the Mixer. You can also route audio (for send effects) for the selected track in the Plug-ins area.
Choose the destination for a send in the Mixer
In Logic Pro, tap the Setup button
in the Mixer menu bar (if it is not already selected).Tap a send, then choose a destination from the Bus pop-up menu, or choose Create New Bus.
You can also choose send destinations in Sends view in the Plug-ins area.
Choose the mode for a send
Sends in Logic Pro can use one of three modes that control whether the signal is affected by volume adjustments, pan adjustments, or both.
In Logic Pro, tap the Setup button
in the Mixer menu bar (if it is not already selected).Tap an active send, then choose one of the send modes:
Post Pan: The signal is sent after the fader and the Pan knob; the send signal is affected by both channel strip volume and pan adjustments. When a send is Post Pan, the Send knob ring is green.
Post Fader: The signal is sent after the fader but before the Pan knob; the send signal is affected by volume adjustments but not pan adjustments. When a send is Post Fader, the Send knob ring is blue.
Pre Fader: The signal is sent before the fader and Pan knob; the send signal is not affected by volume or pan adjustments. When a send is Pre Fader, the Send knob moves to the left of the Send pop-up menu, and the Send knob ring is blue.
Show the routing destination for a send
You can show the routing destination for a send in the Mixer. When Send/Routing Destination is selected, the aux channel strip for the selected send appears on the right side of the Mixer, next to the output channel strip.
In Logic Pro, tap the More button
in the Mixer menu bar, then tap Send/Routing Destination to turn it on.In the Mixer, tap the Bus pop-up menu for a send to select it.
Copy the current channel strip fader volume to the send level
You can copy fader volume from a channel strip directly to a send using the Copy Fader to Send command. Using this command, you can quickly set the level for a send without having to first enter Sends on Faders mode and make adjustments.
In Logic Pro, tap the Setup button
in the Mixer menu bar (if it is not already selected).Tap an active send, then tap Copy Fader to Send to turn it on.
Remove a send
In Logic Pro, tap the Setup button
in the Mixer menu bar (if it is not already selected).Tap an active send, then tap Remove Send.
