202 Chapter 6 Logic’s Mixing Facilities
When multiple Audio Objects are selected, changing their level by moving one fader is
dB-proportional. The mixing ratio of the selected channels remains constant.
An independent monitoring level is available when a Track Object is record enabled.
After arming the track, set the fader to the desired level. The original level will be
restored when the Object is disarmed. The global Toggle (Mute) Audio Tracks key
command switches the levels of all Audio Objects between two different values. Each
Object may be set to any value for both toggle positions, allowing you to quickly
switch between two basic mixes.
You can switch other Object types in the same way, using the global Toggle (Mute)
Audio Inputs, Toggle (Mute) Audio Bus and Toggle (Mute) Audio Outputs key commands.
Solo/Mute
Solo
All Audio Objects have a Solo button. This mutes all other Audio Objects.
Muted Objects are indicated by a flashing M in the Mute button. Please note that this
does not mute MIDI tracks.
You can also solo several Objects at once.
Option-clicking a previously unsoloed Object releases other active Solo buttons,
allowing the selected channel to be heard in isolation (“Interlocking Solo” or “Solo
Toggle”).
Option-clicking any activated Solo button disables the solo status of all Audio Objects.
Solo Safe
If you want to hear the signal of a soloed channel with any bussed effects, the effect
return channels obviously shouldn’t be muted. Unlike conventional mixing desks, Logic
can scan the entire signal path, and leave the effect return channels open.
The same applies when you solo an effect return signal. The channels fed into the
effect are muted, but their effect sends remain open, ensuring that the effect continues
to receive a signal.
This automatic mute-suppression only applies to the internal effect returns. If you are
using external effect units via Bus Objects, the scan will keep the effect master sends
open. Logic cannot, however, know which of the Input Objects you are using as effect
returns for external effect units. You need to manually switch these Input Objects to
“solo safe”—just like on a conventional mixing desk.
