A vertical gray line means that the setting is the same as the line above. If you change
a vertical gray line that is above another vertical gray line, the lower one will change to
display its previous value (it will no longer be the same as the line above.)
Group
To the left of the Region/Folder name is the group column. Groups behave as they do
in the Hyper Editor—when you trigger a Region, any other (currently playing) Region in
the same group will stop.
The off setting means that the Region is not assigned to any group.
Transposition
When you drag a Region to a key in the touch tracks window, that key triggers the
Region at its original pitch (without transposition). If you want the Region transposed,
you can set the amount in the Trp column (±99 semitones).
If a key range is selected when you drag the Region to the touch tracks window,
incremental transpositions will automatically be set for adjacent keys (within the key
range).
When you create a touch tracks Object by dragging a Region into the Environment, C3
triggers the Region at its normal pitch, and all other keys trigger it—transposed relative
to C3.
Velocity Sensitivity
In the Velocity column, you can set the sensitivity of Regions to the velocity value of the
trigger note: by 100% (very sensitive), 50% (somewhat sensitive) or off (not velocity
sensitive).
Trigger Modes
The Trigger column determines how Region playback is handled:
Multi
Playing the trigger note starts the Region. Playing it again restarts the Region, without
stopping playback of the originally triggered version.
Single
Playing the trigger note once starts the Region. Playing it again stops playback, and
restarts the Region.
Gate
The Region plays until the trigger note is released (or until the Region ends).
Gate Loop
The Region loops until the trigger note is released.
