Record with Low Latency Monitoring mode in Logic Pro for iPad
All plug-ins cause timing delays, known as latency, when processing audio. Small delays are not audible; however, the more processor-intensive a plug-in is, the bigger its latency will be. In addition, many channel strips in your project might have different plug-ins, meaning different tracks are played back with a different delay, causing sync issues. Logic Pro automatically applies plug-in delay compensation (PDC) by detecting the channel strip with the maximum latency due to its latency-causing plug-ins, and based on that, delaying the other channel strips in real time by an individual amount so that all tracks play back in sync.
Although this slight playback delay is not a problem when you play back your project during mixing, it makes it difficult to perform with proper timing when you record on a track. To avoid that delay, you can turn on Low Latency Monitoring mode that turns off plug-in delay compensation on the focused instrument track and any record-enabled tracks. This affects the plug-ins and the Aux sends on those tracks:
Bypassed plug-ins: Any plug-in that pushes the track’s total latency value above the set limit is bypassed. Those plug-ins show a gray plug-in button with orange text in the Mixer and an orange plug-in name and Low Latency Monitoring mode icon
in the Details view of the Plug-ins area.Focused instrument tracks show the bypassed slots once you start the playback.
Deactivated Aux sends: Every Send slot is turned off. This is indicated by a gray Send button with orange text and an orange Low Latency Monitoring mode icon
in the Sends view of the Plug-ins area.Tip: A Low Latency Safe option in the Sends pop-up menu lets you turn on a Send slot again, which is useful when you routed the track’s signal to a reverb that you want to hear during recording.
Note: In addition to the plug-in latencies, there are other components that introduce latencies. For example, MIDI controllers connected via Bluetooth, the input and output stage of your selected audio interface, or the I/O Buffer Size value. For details, see Audio Devices settings.
Turn Low Latency Monitoring mode on or off
In Logic Pro, do one of the following:
Tap the Low Latency Monitoring Mode button
in the control bar.The Low Latency Monitoring Mode button does not appear in the control bar by default. To add this button to the control bar, see Customize the control bar.
Tap the More button
in the control bar, tap Settings > App Settings > Audio > General, then tap the Low Latency Monitoring Mode switch.
When you turn on Low Latency Monitoring mode, the Limit field below the Low Latency Monitoring Mode switch appears in the General Audio settings. It lets you determine the maximum amount of allowed latency across the entirety of the record-enabled track’s signal path (up to 30 ms).
WARNING: The sound may change when you turn on Low Latency Monitoring mode. Depending on the plug-ins in use, the change in sound can be anything from subtle to dramatic. If plug-ins being used do not exceed the total latency limit, there is no audible difference.
Reactivate an Aux send in Low Latency Monitoring mode
With Low Latency Monitoring mode turned on, all Send slots on a record-enabled channel strip are turned off. This is indicated by their gray buttons with orange text in the channel strip and by an orange Low Latency Monitoring mode icon in the Sends view of the Plug-ins area.
In Logic Pro, select the record-enabled track and do one of the following:
Tap the Mixer button
in the view control bar to show the channel strip you want to record on.Tap the Plug-ins button
in the view control bar, then tap the Sends button.
Tap the Sends pop-up menu and choose Low Latency Safe.
The Send button changes to blue, and the orange Low Latency Monitoring mode icon
disappears.
To deactivate the Send again, tap the Low Latency Safe option in the Sends pop-up menu to deselect it.
