4 – Operation : Automating Library Recall34 TASCAM DM Automation GuideAutomating Library RecallThe TASCAM DM automation system is capable ofincluding library recall events as part of an auto-mated mix. These are treated by the automation sys-tem as Switch Events.All TASCAM DM libraries support automated recall:• Snapshot• EQ• Compressor/expanders• Gate• EffectsBecause there may be differences between controlsettings recalled by a library and those being playedback by the automation system, below are someimportant things to keep in mind in order to avoidunexpected behavior.The basic rule is that a mix event (library recall ordynamic mix move) only has priority until anothermix event (library recall or dynamic mix move) isplayed back.Writing Library Recall Events Over Existing Static Control PositionsWhen a library recall event is written by the automa-tion system which affects controls in Static mode, thelibrary recall switch event becomes dynamic mixdata. However, the controls themselves remain inStatic mode with their Initial Status unaffected. Inthis case, if a dynamic mix move is written after alibrary recall, the control will Revert to its Initial Sta-tus, not its position after the library recall.If a library is recalled which affects controls in Staticmode without the library recall event being written,the controls will update their static positions as theyhad been directly adjusted.Combining Library Recall With Dynamic Mix MovesDynamic mix moves are treated in a way similar tocontinuous data by the TASCAM DM automationsystem. Library recall events are instantaneous snap-shots. If a library recall occurs while the automationsystem is reading dynamic mix moves, the affectedcontrols will snap to the positions recalled by thelibrary then snap to reading previous dynamic mixmoves as the timecode position crosses the previousdata. While this can create some interesting effectswhen used purposely, it could take you by surprise.
