132 Automation Background Cubase Essential provides very comprehensive automa- tion features. Virtually every mixer and effect parameter can be automated. There are two main methods you can use to automate pa- rameter settings: By manually drawing curves on automation subtracks in the Project window. See “Editing automation events” on page 138. By using the Write/Read buttons and adjusting para- meters in the mixer. See “Using Write/Read automation” on page 135. The methods are not different in terms of how the automa- tion data is applied – they only differ in the way the auto- mation events are created; manually drawing them or recording them. Any applied automation data will be re- flected in both the mixer (a fader will move for example) and in a corresponding automation track curve (although this may be hidden). About automation subtracks Audio tracks, group channel tracks and FX channel tracks all have automation subtracks. These allow you to view and edit the automation of all mixer settings for the track, including settings for the track’s insert effects. For each track a single automation subtrack for one parameter can be shown, but you can change the parameter any time. Similarly, MIDI tracks have automation subtracks for mixer settings, track parameters and (if used) for send and insert effect settings. VST Instruments have special automation tracks that ap- pear in the Project window when you add a VST Instrument. There is one automation track for the plug-in parameters, and one track for each mixer channel used by the instru- ment. These tracks all have automation subtracks, giving you access to all parameters and mixer settings. Instrument tracks, as a combination of a MIDI track and a VST Instrument, have automation tracks that provide auto- mation parameters for the VST Instrument itself, for the VST Instrument channel and the respective MIDI automa- tion parameters. Finally, for ReWire channels and output channels, auto- mation tracks are automatically added as soon as you ac- tivate automation (with the Write button) in the corresponding mixer channel strip or in the Channel Set- tings window. These automation tracks have subtracks for all parameters as well.
133 Automation What can be automated? Mixing in Cubase Essential can be completely automated. The following parameter settings can be recorded auto- matically – or manually drawn in – on automation sub- tracks: For each audio or group track and ReWire channel: 8 x insert effect parameters and bypass (if inserts are used) 8 x effect send settings (on/off, level, pan) Settings for 4 EQ modules (Master Bypass, on/off, Type, Gain, Freq., Quality) For each FX channel track and output bus: 8 x insert effect parameters and bypass (if inserts are used) Settings for 4 EQ modules (Master Bypass, on/off, Type, Gain, Freq., Quality) For each VST Instrument: VST Instrument plug-in parameters and program selection plus (for each mixer channel/separate output used by the instrument): 8 x insert effect parameters and bypass (if inserts are used) 8 x effect send settings (on/off, level, pan) Settings for 4 EQ modules (Master Bypass, on/off, Type, Gain, Freq., Quality) For each MIDI track: MIDI Modifiers on/off switch Random 1-2 min/max/target Range 1-2 min/max/target 4 x insert effect on/off switches 4 x send effect on/off switches 4 x MIDI insert effect parameters (if used) 4 x MIDI send effect parameters (if used) For each Instrument track: As Instrument tracks are a combination of a MIDI track, an instrument and an Instrument Return channel in the Mixer, the automation subtracks for instrument tracks feature all parameters that are available for VST instruments plus the parameters for MIDI tracks (see the respective sections above) except MIDI Volume, Pan and Mute, because the parameters Volume Pan and Mute are controlled directly via the Instrument Return channel in the Mixer. Automation track operations Opening automation subtracks Every track/channel has one automation subtrack, show- ing one automation parameter. For audio, Instrument, group channel, MIDI and FX chan- nel tracks, there are two ways you can open an automa- tion subtrack for the channel: By right-clicking the track in the Track list and selecting “Show Automation” from the context menu. By clicking on the left border of the track in the Track list. (When you position the mouse pointer over the lower left corner of the track, the respective arrow icon (“Show/ Hide Automation”) appears.) An automation subtrack opens in the Track list, and a straight black hori- zontal line is shown as well as a greyed out mirror image of the audio events’ waveform (or MIDI events for MIDI tracks) in the event display. When you open an automation subtrack for the first time, the Volume pa- rameter is selected by default. Click here to open the automation subtrack.
134 Automation For VST Instruments (not for Instrument tracks, see above), automation tracks appear automatically when you add them in the VST Instruments window. For ReWire channels and output busses, automation tracks are automatically created when the Write automa- tion button (see “Using Write/Read automation” on page 135) is activated in either: The corresponding channel strip in the mixer. The corresponding Channel Settings window. The mixer common panel (“All Automation to Write Status”). The area above the Track list (“All Automation to Write Status”). Assigning a parameter to an automation track By default the Volume parameter is assigned to the auto- mation track when you open it for the first time. To select what parameter an open subtrack should dis- play, proceed as follows: 1.If none exists, open an automation subtrack using one of the methods described above. 2.Click in the parameter display for the automation sub- track. A pop-up list is shown, containing some of the automation parameters plus the item “More...” at the bottom of the list. The contents of the list depend on the track type (audio, MIDI, VST instrument, etc.). If the parameter you wish to automate is on the pop-up menu, you can select it directly. The parameter will then replace the current parameter in the automation subtrack. If you wish to add a parameter not available on the pop- up menu or want to view all parameters that can be auto- mated, go on to the next step. 3.Select “More...”. The Add Parameter dialog appears. This dialog shows a list with all pa- rameters that can be automated for the selected channel (sorted into dif- ferent categories), including the parameters for any assigned insert effects. See “What can be automated?” on page 133 for a list of the available parameters according to channel type. To view the parameters in each category click the “+” sign for the category folder. The Add Parameter dialog for an audio track. 4.Select a parameter from the list and click OK. The parameter will then replace the current parameter in the automation subtrack. ÖNote that the “replacing” of the parameter displayed in the subtrack is completely non-destructive. For example, if the subtrack contained any automation data for the pa- rameter you just replaced, this data will still be there, although it will not be visible after you replaced the parameter. If you click in the parameter display you can switch back to the replaced parameter. All automated parameters are indicated by an asterisk (*) after the parameter name on the pop-up menu. The Volume parameter is automated.
135 Automation Removing automation subtracks To remove all automation for the selected parameter, click the parameter name and select “Remove Parameter” from the pop-up menu. This will delete any automation events on the subtrack, and the subtrack will be closed. Hiding automation subtracks To hide an automation subtrack, position the pointer over the top left border of the subtrack in the Track list and click the “Hide Automation Track” button. To hide an automation subtrack, you can also right-click the corresponding track, and select “Hide Automation” from the context menu. To hide all automation subtracks for all tracks in the Track list, right-click any track and select “Hide All Auto- mation” from the context menu. This option is also available in the Project menu. Muting automation subtracks You can mute individual automation subtracks by clicking their Mute buttons in the Track list. Clicking the Read (R) button (see “Using Write/Read automation” on page 135) for an automation subtrack will activate or deactivate Read mode for all automated parameters of the track. Using the Mute button allows you to turn off automation for a single parameter. The “Automation follows Events” setting If you activate “Automation follows Events” on the Edit menu (or in the Preferences–Editing page), automation events will automatically follow when you move an event or part on the track. This makes it easy to set up automation related to a spe- cific event or part, rather than to a specific position in the project. For example, you can automate the panning of a sound effect event (having the sound pan from left to right, etc.) – if you need to move the event, the automation will automatically follow! The rules are:All automation events for the track between the start and end of the event or part will be moved. If there are automation events in the new position (to which you move the part or event), these will be overwritten. If you copy an event or part (using Copy/Paste, or [Alt]/ [Option]-dragging, or using the Duplicate or Repeat func- tions), the automation events will be duplicated as well. Using Write/Read automation All track types except folder, marker and video tracks fea- ture Write (W) and Read (R) buttons in the mixer, in the Track list and in the Channel Settings window. Further- more, the control panels for all plug-in effects and VST In- struments also feature Write and Read buttons. The Write and Read buttons for a channel in the mixer and for an auto- mation subtrack in the Track list. If you activate Write for a channel, all mixer parameters you adjust during playback for that specific channel will be recorded as automation events. If you activate Read for a channel, all your recorded mixer actions for that channel will be performed during playback, just like you performed them in Write mode. The W and R buttons for a track in the Track list are mir- rors of the W and R buttons in the corresponding channel strip in the mixer. There are also global Read and Write buttons in the com- mon panel of the mixer and at the top of the Track list: The global Write and Read buttons in the mixer, and in the Track list. When “All Automation to Read Status” is activated, all your recorded mixer actions for all channels will be per- formed during playback.
136 Automation When “All Automation to Write Status” is activated, all mixer actions you perform during playback (for all chan- nels) will be recorded as automation events. The “MIDI Controller Input to Automation Tracks” preference If you have set up a remote device to control parameters and settings in the program, you can record automation with that remote device – just activate Write as usual. However, if you are recording a MIDI track and want to record automation at the same time, the controller data sent by the remote device will be recorded “twice” – as automation and as MIDI controller data on the MIDI track. To avoid this, activate the “MIDI Controller Input to Auto- mation Tracks” setting in the Preferences (MIDI page). When this is activated, the controllers will be recorded as automation only, not as MIDI controller data on the re- corded MIDI track. Recording your actions – an example If the settings in your current project are crucial, you may not want to “experiment” with automation until you know more about how it all fits together. If so, you can create a new project for the following example. It doesn’t even have to contain any audio events, just a few audio tracks. Pro- ceed as follows: 1.Open the Mixer window. 2.Click the global Write button (“All Automation to Write Status”) in the mixer common panel. Cubase Essential is now in global Write mode. 3.Start playback and adjust some volume faders and/or other parameter settings in the mixer or perhaps in a Channel Settings window. Stop playback when you are done, and return to the position where you started playback. 4.Deactivate Write mode and click the global Read but- ton (“All Automation to Read Status”) in the mixer com- mon panel. Cubase Essential is now in global Read mode. 5.Start playback, and watch the Mixer window. All your actions performed during the previous playback will be repro- duced exactly. 6.If you wish to redo anything that was recorded, acti- vate Write mode again and start playback from the same position. You can have Write and Read activated simultaneously, if you want to watch and listen to your recorded mixer ac- tions while you’re recording fader movements for another mixer channel, etc. Recording plug-in automation Every parameter for every assigned effect or VST Instru- ment can be automated in much the same manner as de- scribed above. The following example assumes that you have assigned an insert effect to an FX channel track (see the chapter “Au- dio effects” on page 103), and describes how to record automation for the effect: 1.Select the FX channel track in the Track list and open its Inserts section in the Inspector. If the Inspector is hidden, click the “Show Inspector” button in the Project window toolbar. ÖPlease note that not all Inspector tabs are shown by default. You can show/hide Inspector sections by right- clicking on an Inspector tab and activating/deactivating the desired option(s). Make sure to click on an Inspector tab and not on the empty area below the Inspector, as this will open the Quick context menu instead. 2.Open the control panel for the effect by clicking the Edit button (“e”) above the insert effect slot in the Inspector. 3.Click the Write button in the control panel to activate Write mode. All effects and VST Instruments have Write/Read buttons on their control panels. These work exactly like the corresponding buttons in the mixer or in the Track list. In the previous example, we used global Write mode, in which mixer and parameter changes are recorded on all tracks, but in this example we’ll use Write mode for one track only. 4.Start playback and adjust some effect parameters in the control panel. When you are finished, stop playback and return to the position where you started playback. 5.Deactivate Write and instead click the Read button on the control panel. 6.Start playback and watch the control panel. All actions you performed during the previous playback will be repro- duced exactly.
137 Automation Assigning an automated parameter to an automation subtrack To select which parameter is currently shown in the auto- mation track for the FX channel, proceed as follows: 1.Click on the parameter name for the FX channel auto- mation subtrack. The parameter name pop-up list is shown containing the automation pa- rameters for the plug-in. The parameter(s) you previously automated are indicated by an asterisk after the parameter name in the list. Automated parameters for the PingPongDelay effect 2.Select the parameter you wish to view from the para- meter display pop-up. The automation curve for the parameter you selected is displayed on the automation subtrack. To view VST Instrument parameters, you use the same method. As described earlier, each VST Instrument has two or more automation tracks – one for the plug-in settings and one for each VST Instrument mixer channel. Where did the automation data I recorded end up? When using global Write automation, you can write auto- mation data on the automation tracks of all channels. In the previous write operations, you probably added auto- mation events for many different channels and parameters. To view all the automation events you recorded during the operations, select “Show All Used Automation” from the Project menu or from the Track list context menu. For each of the channels one subtrack with automation data is now shown in the Project window. The automation events recorded are shown as points in the automation curves. Working with automation curves About automation curves There are two kinds of automation curves, “ramp” and “jump”: Jump curves are created for any parameter that only has on/off values, like a Mute button, for example. Ramp curves are created for any parameter that gener- ates continuous multiple values, such as fader or dial movements etc. Examples of jump and ramp automation curves shown in the event dis- play. About the static value line When you first open an automation subtrack for a para- meter, it doesn’t contain any automation events (unless you have previously adjusted that parameter with write au- tomation activated), and this is reflected in the event dis- play as a straight horizontal black line, the “static value” line. This line represents the current parameter setting. If you have manually added any automation events or used write automation for the corresponding parameter, and then deactivate Read mode, the automation curve will be grayed out in the automation subtrack event display and the static value will be used instead. As soon as Read mode is activated, the automation curve will become available.
138 Automation Editing automation events Drawing automation events By using write automation in the mixer, you generate auto- mation events by moving parameter dials and faders in the mixer. You can also add them manually by drawing automa- tion curves on an automation subtrack. Proceed as follows: 1.Show the automation subtrack by clicking on the left edge of the track in the Track list. The static value line is shown in the event display for the automation sub- track. 2.Select the Pencil tool. You can also use the various modes of the Line tool for drawing curves, see below. 3.If you click on the static value line, an automation event is added, read automation mode is automatically activated, and the static value line changes to a blue automation curve. 4.If you click and hold, you can draw a curve by adding a multitude of single automation events.5.When you release the mouse button, the number of automation events is reduced to a few events, but the ba- sic shape of the curve still remains the same. This “thinning out” of events is governed by the Automation Reduction Level setting in the Preferences (Editing page), see “About the Automa- tion Reduction Level preference” on page 140. 6.If you now activate playback, the volume will change with the automation curve. In the mixer, the corresponding fader moves accordingly. 7.Simply redo the operation if you are not happy with the result. If you draw over existing events, a new curve is created. If the automation subtrack is in Read mode already, you can also add automation events by clicking with the Arrow tool. If you are trying to add a point between two existing points and the new point doesn’t deviate from the existing curve, it will be removed by reduc- tion as soon as you release the mouse button (see “About the Automa- tion Reduction Level preference” on page 140). Using the various modes of the Line tool to draw automation curves The Line tool can be very useful for drawing automation events. The various modes are accessed by selecting the Line tool on the toolbar, clicking on it a second time and selecting from the pop-up menu that appears. Clicking and dragging with the Line tool in Line mode shows a line in the automation subtrack and creates auto- mation events aligned with this line. This is a quick way to create linear fades, etc.
139 Automation The Line tool in Parabola mode works in the same way, but aligns the automation events with a parabolic curve in- stead, resulting in more “natural” curves and fades. Note that the result depends on the direction from which you draw the parabolic curve. The Sine, Triangle and Square Line tool modes create automation events aligned with continuous curves. If snap is activated and set to Grid, the period of the curve (the length of one curve “cycle”) is determined by the grid setting. If you press [Shift] and drag, you can set the period length manually, in multiples of the grid value. Selecting automation events To select a single automation curve point, click on it with the Arrow tool. The point turns red, and you can drag it in any horizontal or vertical direc- tion between two points. To select multiple curve points, you can either [Shift]- click or drag a selection rectangle with the Arrow tool. All events inside the selection rectangle will become selected. Drawing a selection rectangle around some points to select them. When selected, the points can be moved in all directions as “one”, i.e. the curve shape formed by the selected points remains intact.To select all automation events on a subtrack, right-click the automation subtrack in the Track list and choose “Se- lect All Events” from the context menu. Removing automation events There are several ways to remove event points: By selecting points and pressing [Backspace] or [De- lete] or selecting Delete from the Edit menu. By clicking on a point with the Eraser tool. By selecting a range (with the Range Selection tool), and pressing [Backspace] or [Delete] or selecting Delete from the Edit menu. By clicking in the parameter display on a subtrack and selecting “Remove Parameter” from the pop-up. This will remove all automation events from the subtrack, and the sub- track will be closed. Editing automation events Automation events can be edited much like other events. You can use cut, copy and paste, you can group and nudge events etc. There are, however, four items on the Edit menu that are not applicable to automation events. These are: Split at Cursor Split Loop Move to Front
140 Automation Tips and common methods There are no hard and fast rules when it comes to describ- ing which automation method you should use. You can for example never even open an automation subtrack, and stick with write automation throughout a project. Or you can stick to drawing automation curves to automate set- tings in a project. Both methods have their advantages, but it is of course up to you to decide what to use and when. Editing curves on automation subtracks offers a graphi- cal overview in relation to the track contents and the time position. This makes it easy to quickly change parameter values at specific points, without having to activate playback. For example, this method gives you a good overview if you have a voice-over or a dialog on one track and a music bed on another track, the level of which needs to be lowered with a specific amount every time the dialog occurs. By using write automation in the mixer you don’t have to manually select parameters from the Add Parameter list. You can work much like you would using a “real” physical mixer. Every action you perform is automatically recorded on subtracks which you can later open for viewing and editing of the parameters you changed. These are just two examples of advantages for each method. Generally, editing curves and using write automa- tion are two methods that complement each other, and de- pending on the nature of your projects you will probably work out what method works best for a given situation. Options and Settings About the Automation Reduction Level preference This item can be found on the Editing page in the Prefer- ences. Automation reduction reduces the number of auto- mation events after you have used write automation or added automation events manually. When you write auto- mation events or draw them with the Pencil tool, these are added as a continuous stream of densely packed events. This is necessary because the program cannot “guess” what you will be doing next. However, when you are done, the reduction function will remove all superfluous event points and the automation curve now contains only the event points necessary to reproduce your actions. For example, all event points that lie between two other points, but do not deviate from the curve, will be automat- ically removed by reduction. If you try to add an event that doesn’t deviate from the existing curve between two existing points... ...it will be removed when the mouse is released. If you move the se- lected event by any amount so that the resulting curve isn’t a straight line, the event will of course be added. If you feel you need a lower (or higher) reduction level of events than the default setting of roughly 75% reduction, you can change it, but normally the default setting works well. A minimum reduction level setting is not recommended as this will simply retain a lot of unnecessary events.
