The following analysis of the example Pass Tree in Figure 13-14 explains most of the
Tree’s features:
• Pass 1 contains additional automation but is based on automation created in
Pass 0. Pass 1 may have new automation, modify Pass 0’s automation, or both.
• Pass 2 is derived from Pass 1 in a similar manner as Pass 1 from Pass 0.
• Pass 3 is derived from Pass 2.
• Pass 4 is derived from Pass 2, not from Pass 3. Pass 3 may have been an exper-
iment the user wished to save but not continue using.
• Pass 5 is derived from Pass 4.
• Pass 6 is derived from Pass 5.
• Pass 7 is derived from Pass 6.
• Pass 8 is derived from Pass 5, not from Pass 7. Passes 6 and 7, like Pass 3, have
been saved but not used to continue in the Tree.
Prune Tree
Pruning the mix tree deletes all passes that are not in the direct line from the first to the
last pass. In Figure 13-14, passes 3, 6, and 7 would be deleted but the existing numbers
are retained. This frees up space and simplifies complicated trees. Prune the tree only
when you are sure you will not need the information in those passes.
1. Press the Prune Tree key in Automation Panel Page 2.
2. Confirm at the bottom of the panel to prune the pass tree.
Pack Tree
Packing the mix tree merges all automation data from previous passes into the current
pass so only one pass remains in the new mix tree. Conflicting data for any parameter
is resolved by using the later pass. Although this frees up space and simplifies complicated
trees, similar to Prune Tree, it preserves all automation in the tree.
1. Press the Pack Tree key in Automation Panel Page 2.
2. Confirm at the bottom of the panel to pack the pass tree.
Merge Trim
Merge Trim adds the Trim data to the Absolute automation. This operation does not
change the audio but does set the Trim automation to zero. When a Trim move yields a
satisfactory modification, it is simpler to use Merge Trim to keep all the automation in
the Absolute domain. Merge Trim also permits the full 15 dB range for further trim
operations, if necessary.
