3 – Automation overview : Modes10 TASCAM DM Automation GuideTrimDuring a mix there may be sections where there aregood mix moves on a control but the overall level ofthat control needs to be raised or lowered while pre-serving the existing moves.Trim mode is used to make such relative offsets toexisting mix moves for the duration of the Trim oper-ation. The diagram below should help in the under-standing of this concept.In the example shown above, a fader is raised at the“Begin Trim” point and released at the “End Trim”point. The upward movement of the fader would beadded to the existing data. When a Trim is per-formed, the audio passing through the controlincludes the Trim move in real time.StaticDuring the course of an automated mix some con-trols will require movement (Dynamic automation),and some controls will stay in one place with theirsettings stored in the mix file (Static automation).Any control in Static mode will automatically updateits setting in the mix file whenever that control ismoved.NOTEThe control’s movement will not be recorded asdynamic automation as long as Write mode is notenabled.SafeAny control in Safe mode will only read existingstatic or dynamic automation. Moving a control inSafe mode will not write any automation data noraffect the audio passing through that control. It ispossible to place all mixer controls in Safe mode byholding the SHIFT key while pressing ALL SAFE.OffThis mode removes a control from the automationsystem completely. A control that is Off cannotrecord or playback mix moves. However, moving acontrol that is Off will affect the audio passingthrough that control.Figure 5: Illustration of trim mode behavior8 sec8 sec+12+6+30-3-6-12+12+6+30-3-6-121 sec 2 sec 3 sec 4 sec 5 sec 6 sec 7 sec1 sec 2 sec 3 sec 4 sec 5 sec 6 sec 7 sec-9Before TrimAfter TrimBegin Trim End TrimRevertTime
