The Automations

This month, I propose you a big part which will change your life if you don't know anything about it. Professional sequencers air a pretence : to be able to replace all the hardware elements present in a real recording studio. We wouldn't have forgiven them if an Automation system was not integrated. You can notice how things are well done : Automation is precisely one of the points on which Steinberg fully reviewed their work between VST and SX !


Fulliautomatix !

First of all, let's answer to this question : Automation, whuzthat ? Automation, present on every mixboards we can find in pro recording studios, is a system which will memorize and « playback » the whole variations applied to the different parameters of the mixboard, fader, Eq, effect level, etc. Now, computer science goes further. As all the virtual studio elements (the sequencer itself but also the effects and the virtual instruments) are managed by the sequencer, they will be all « automatizable » ! In short : added to the variations applied to the mixboard, you will be able to manage the parameter changes of your dear plug-ins too !

Cubase SX makes the distinction between 3 types of automation, the Audio tracks one, the VSTis and Plugins one, and the Master effects one (read Musicrun 2). Mainly, their handling and their management will be the same but their utility will differ. Let's begin with the basic principles...
The 1st method for writing an automation is the « I'm very lazy » method ! Did you notice the « R » and « W » buttons disseminated a little bit everywhere in the software interface ? R for Read, W for Write. Let's go for a little practice exercise.
On an Audio track, click on the button « W » so that it becomes red. Start the playback and, for example, modify the volume during the reading of the song. Stop the playback, go back to the starting of the track, deactivate the « W » and click on the « R » (it becomes green). Play, so ? Hum


If you did it well, the volume fader will reproduce the movements you applied to it during the previous stage. Important thing, an Automation « subtrack » has been created below the Audio track itself but it is hidden for the moment ! In order to display the automations...
…For each track, in the track column, you can see a small « + » downleft. By clicking on it, you make appeare the Automation track which is related to it. Each new click on a « + » adds an Automation subtrack with another parameter. There are 48 parameters.
The contextual menu allows to quickly hide or display the Automations. Notice that those options are also available in the « Project » menu. This was a first approach which make it already possible to do many things. Let's jump now to the following stage : the Pencil tool !


To your pencils…

The automation being explained like that would be even so a little bit rustic if there weren't some powerful possibilities of writing and editing those Automations. Those vital functions for such a sequencer are as simple to use in SX as they were puzzling in VST ! The « ancients » will understand me ! In SX, each point can be edited with the mouse, you can draw them with the pencil with some preset « shapes », handle them per group, etc. And of course, in case of error, a good old CTRL-Z will allow you to go back thanks to the unlimited Undo, another major improvement of SX. SX 2 promises us besides to go further, watch the test in a coming chapter !

Practice exercises. Choose an Audio track. Click on the « + » to display the automation subtrack. By default, the volume parameter is proposed. The pop-up menu makes it possible to choose another parameter among the 48 quoted previously. Click on « Sum » to have access.
Let's take « Panner - Pan Left-Right ». The green line represents the Automation itself. For the moment, it is a straight line and steady on the actual value of the Pan in the Mixboard. Clicking on the line with the « Select » tool adds an Automation point which can then easily be handled.
The aim of the game is to create as many points as needed and to arrange them so that you can obtain the expected variations. The job is made easy by the fact that a tooltip indicates the position and the point value. I will now give to you some additional tricks.


With the « Select »tool, you can circle several points and then handle them at the same time. If a point is already at its maximum or minimum value, unselect it by clicking on it with the Shift key holt down. To erase one, select it and... Delete !
The « Pencil » tool is much more interesting because it makes it possible to draw some complex Automations on the fly and fastly. Simple use : select « Pencil » in the contextual menu and draw your curve directly on the Automation track. It's easy !
You will then notice that SX deletes the unnecessary points (those which are located in the alignment of 2 extreme points). The sensibility of this correction can be adjusted in the preferences (File menu) at the Editing / Automation Reduction Level section... Next !


Look at the Pencil icon in the Tool Bar. The small arrow indicates that the tool proposes some other options. The Pencil sets at your disposal some preset shapes Line, Parabola, Sinus, Triangle and Square. They can be used as the pencil except that... They can be quantized !
To do this, before drawing a curve, you just need to activate the Snap (>|< icon), to choose « Grid » just on the right, then Quantize again on the right. To end, select a Quantize resolution, your curves will be now faithful to your adjustments. Not bad, no ?
Just a word about the Master Automation. You must insert a dedicated track but the reminder of the working is similar. You can act on the main volume, on the busses volume (depending of those proposed by the soundcard) and on the input level of the 8 Master Plug-ins.


Plug-ins Automation

We intended for the moment the mixboard Automation only. Let's see now what happens with the Plug-ins, either they are effects or virtual instruments. First of all, we must accept an evidence : all the Plug-ins are not on equal terms in front of the Automation. Cubase's one concerns Steinberg's responsability. Each Plug-in's one depends of the will of its creator ! A parameter would be automatizable if the programer has foreseen this ! What will follow depends thus on the program which is used. You would have understood that, here, we will use automation to act on all the Plugin parameters and to make them varying in time. Action !


Well, first thing, in order to display the Automation track of an effect or a VSTi, you must click on the « W » of its interface. A bit hard to find... As for Audio tracks, the pop-up presents you the parameters that the programer was kind to set at your disposal.
Of course, you can generate some variations, either by moving the buttons while the button « W » of the plugin is active or by using the Pencil and Select tool, as seen previously. Another common point, by clicking on the small +, it is possible to show as many parameters as wanted.
Hey, it's a trick which doesn't appear in the manual, besides! How to copy-paste an automation? With the « Range » tool, select the part to be copied and do CTRL-C. Select then the destination and do CTRL-V. You just need to learn to aim accurately ;o)


And now, as it is my kindness day, another one ! We saw that we can now quantize some preset curves of the pencil. But, by holding down the Shift key before starting to draw, you will be then fully free to determinate yourself the periods length.
Raaah, they want some more ! Ok ! If editing with the mouse rebuffs you, you will be amazed to learn that the Automation Events can be edited in the Explorer (CTRL-B). Things being well done, the Explorer directly wedges on the selected Event.
The Inserts ? They add their own parameters to the Audio tracks' ones. On second thoughts, that seems to be logical ! Notice also that the Midi tracks can be driven too, volume, pan, mute, transpose, velocity, etc. On another hand, the Midi plug-ins are not taken into account.


Concerning the VST Instruments, their Automation differs because of the high number of parameters which can bring into play in comparison with an effect. I counted 147 parameters for LM4 MKII and 66 for Xphraze ! To you the happiness of the filter variations and other resonance to your synths !
About the Master, effects, their Automation is grouped with the Master's one quoted above. Here again, the possibilities will depend of the will that had the programer of inserting the automation or not. This could be even so a decisive criterion when choosing a plug-in...
Here we are about this short review of the Automation ! Just for this reason, the upgrade from VST to SX meets the case. Watch the imminent arrival of SX 2.0 (official release on 09.04.2003) because it promises to go further into the step according to the first information. See ya soon, here or somewhere else ,o)
