In Logic Pro, select the object, then choose New > Alias.
In Logic Pro, choose New > Fader > Specials > Alias Assigner.
A meta fader, with a -1- definition set to 46, is created.
To use the alias assigner, cable its top output to the alias, and cable subsequent outputs to the various originals that you want to assign to the alias. If you set the alias assigner’s maximum range to match the number of originals and its minimum range to 1, you can then connect the next cable to a new alias, and subsequent cables to originals for the alias. In this way, the alias assigner can be used to assign multiple aliases simultaneously.
One situation in which you might use an alias assigner is when switching a delay line alias between different originals (different delay line objects), each set to different delay times. This method is one of several ways to provide MIDI control over delay time.
If you copy an alias, you create a new alias of the same original. If you select and copy both an alias and its original, you create a copy of the original with its own, separate alias.
