Display audio engine overload message checkbox: When selected, displays an alert message in an overload situation. Otherwise, playback simply stops without displaying an alert.
Sample Accurate Automation pop-up menu: Determines which parameters, if any, are automated with sample accuracy. This type of automation is very processor intensive. It places higher overheads on system resources, which may affect performance (depending on the nature of your projects, and available computing power). This is most likely to happen during heavy project sections where a lot of software instruments and effects are in use. Logic Pro for Mac offers three settings:
Off: Minimal overhead on computer performance for automation playback. Automation is less precise when this setting is active.
Volume, Pan, Sends: Only these parameters are automated with sample accuracy.
Volume, Pan, Sends, Plug-in Parameters: All of these parameters are automated with sample accuracy. Not all Audio Units plug-ins can be automated in this way.
Automatic Bus Assignment Uses pop-up menu: Choose whether automatic bus assignment uses all busses, or only busses above a certain number (in multiples of eight).
Software monitoring checkbox: Turns software monitoring on or off. In most situations, you should leave it on (default).
Note: When software monitoring is on, the audio signal is processed via software, and a certain amount of audible delay (commonly referred to as latency) is inevitable.
If you’re listening to the recorded signal through your mixing console, or your audio interface supports hardware monitoring, you should turn this option off.
Input monitoring only for the focused track, and only when input monitoring is enabled (as in GarageBand) checkbox: When selected, you only hear incoming audio for the focused track, and only if its Input Monitoring button is selected. If you selected multiple tracks, click the track number in a track header to focus that track. When the checkbox is unselected, you hear incoming audio on all tracks that have the Input Monitoring button selected.
Note: The Input Monitoring button on any non-focused track remains gray when selected, and the letter I on the button turns orange to indicate that the button is selected but inactive. The level meter shows the input signal on all tracks that have the Input Monitoring button selected (active or inactive).
Tip: With this input monitoring option, you can set up several audio tracks to receive your audio input and select Input Monitoring on all of those tracks, but you’ll only hear your audio signal on the focused track. This can be helpful when you want to quickly step through tracks to hear your voice or guitar sound with a different Work with plug-in latencies.
Important: Low Latency Monitoring mode is inactive when you bounce your project.
