Virtual Track Table FieldNames
VTTB Virtual Track Table Complex Value
VTSI Virtual Track Start Index Integer
VNUM Max Number Virtual Tracks Integer
VTGR Virtual Table Group Complex Value
VGRP Virtual group number Integer (group number representing the physical
track number)
(if a group entry is not present, then
it is assumed to
have no virtual tracks assigned to
it.)
VCLP Collapsed Virtual Group Integer (0, or 1; 1 meaning collapsed))
TKIN Track Index Integer (reference to the TKIN found
in the track list (TKLS))
3) New Project complex value attribute: User Groups Table
This new attribute must optionally be placed before the TrackList
(TKLS) in the project file. User groups are added to define groups of
tracks for editing or selection. A User group has a name attribute,
a group id, and contain a uniques list of track indexs (TKIN) to define
the tracks associated with a particluar group. It is incorrect to have a
track assigned to more than one group (if encountered, the first assignment
will hold). The track indexes can be any track defined in the project,
but is not meant to be used with non-editable virtual tracks, but is meant
to be used with editable virtual tracks.
