21 Setting up your system Optimizing audio performance This section gives you some hints and tips on how to get the most out of your Cubase Essential system, perfor- mance-wise. Some of this text refers to hardware proper- ties and can be used as a guide when upgrading your system. This text is very brief. Look for details and current information on the Cubase Essential web site (see “How you can reach us” on page 7)! Two aspects of performance There are two distinct aspects of performance in respect to Cubase Essential: Tracks and effects Simply put: the faster your computer, the more tracks, ef- fects and EQ you will be able to play. Exactly what consti- tutes a “fast computer” is almost a science in itself, but some hints are given below. Short response times (latency) Another aspect of performance is response time. The term “latency” refers to the “buffering”, i. e. the temporary stor- ing, of small chunks of audio data during various steps of the recording and playback process on a computer. The more and larger those chunks, the higher the latency. High latency is most irritating when playing VST Instru- ments and when monitoring through the computer, i. e. when listening to a live audio source via the Cubase Es- sential mixer and effects. However, very long latency times (several hundred milliseconds) can also affect other pro- cesses like mixing, e. g. when the effect of a fader move- ment is heard only after a noticeable delay. While Direct Monitoring and other techniques reduce the problems associated with very long latency times, a sys- tem that responds fast will always be more convenient to work with. Depending on your audio hardware, it may be possible to “trim” your latency times, usually by lowering the size and the number of buffers. For details, refer to the audio hardware documentation, or, if you are us- ing a DirectX driver under Windows, the dialog help. System factors that affect performance CPU and processor cache It goes without saying that the faster the computer pro- cessor, the better. But there are a number of factors that affect the apparent speed of a computer: the bus speed and type (PCI is strongly recommended), the processor cache size and of course, the processor type and brand. Cubase Essential relies heavily on floating point calcula- tions. When shopping for a processor, please make sure you get one that is powerful in calculating floating point arithmetics. Note also that Cubase Essential features full support for multi-processor systems. So, if you own a computer system with more than one processor, Cubase Essential can take advantage of the total capacity and evenly distribute the processing load to all available processors. See “The ad- vanced options” on page 22. Hard disk and controller The number of hard disk tracks you can record and play back at the same time also depends on the speed of your hard disk and hard disk controller. If you use E-IDE disks and controllers, make sure that the transfer mode is DMA Busmaster. Under Windows, you can check the current mode by launching the Windows Device Manager and looking for properties of the IDE ATA/ATAPI Controller’s primary and secondary channel. DMA transfer mode is en- abled by default, but may be turned off by the system should hardware problems occur. Audio hardware and driver The hardware and its driver can have some effect on re- gular performance. A badly written driver can reduce the performance of your computer. But where the hardware driver design makes the most difference is with latency. This is especially true when using Cubase Essential for Windows: Under Windows, ASIO drivers written specifically for the hardware are more efficient than a DirectX driver and produce shorter latency times. !Again, we strongly recommend that you use audio hardware for which there is a specific ASIO driver!
22 Setting up your system Under Mac OS X, audio hardware with properly written Mac OS X (Core Audio) drivers can be very efficient and produce very low latency times. However, there are additional features currently only available with ASIO drivers, such as the ASIO Positioning Protocol. Making settings that affect performance Choosing a driver for your audio hardware As described in the section “Selecting a driver and making audio settings in Cubase Essential” on page 16, it is rec- ommended to install and use a standard ASIO driver if available for your specific hardware. Check the manufac- turer’s web site for the latest drivers, etc. Making audio buffer settings Audio buffers affect how audio is sent to and from the audio hardware. The size of the audio buffers affects both the la- tency and the audio performance. Generally, the smaller the buffer size, the lower the latency. On the other hand, work- ing with small buffers can be demanding for the computer. If the audio buffers are too small, you may get clicks, pops or other audio playback problems. Under Mac OS X, you can adjust the size of the buffers on the VST Audio System page in the Device Setup dialog. You may also find buffer settings in the control panel for the audio hard- ware. Under Windows, you adjust the buffer size settings in the control panel for the audio hardware (opened by click- ing the Control Panel button on the driver page in the De- vice Setup dialog). The advanced options On the VST Audio System page you will find the “Advanced options” section. Here you find advanced settings for the VST Engine, including a Multi Processing option. When this is activated (default setting if you have a hyper-threading or multiple-CPU system) and there is more than one CPU in your system, the processing load is distributed evenly to all available CPUs, allowing Cubase Essential to make full use of the combined power of the multiple processors. See the dialog help for details. Optimizing processor scheduling (Windows only) To get the lowest possible latencies when using ASIO un- der Windows XP (on a single-CPU system), the “system performance” has to be optimized for background tasks: 1.Open the Windows Control Panel from the Start menu and select System. 2.Select the Advanced tab and click the Settings button in the Performance section. The Performance Options dialog appears. 3.Select the Advanced tab. 4.In the Processor Scheduling section, select “Adjust for best performance of: Background services”. 5.Click OK to close the dialogs.
24 Tutorial 1: Recording audio Creating a new project In this section we are going to explain how to create a new project, save a project and open a saved project. When you first open Cubase Essential an empty screen appears before you. You need to either create a new project or open an existing one. To create a new project 1.Let’s create a new project by selecting “New Project” from the “File” Menu. 2.The Templates dialog box will open up. Templates are discussed in the “File Handling” section of the Operation Manual. 3.Choose “Empty”. This will create a new project with nothing in it. 4.Click “OK”. 5.Cubase Essential now wants to create a folder on the hard drive so that your Cubase Essential project file and all of its related files are stored in one safe place. It is important that every project gets stored in its own folder. Having many different projects stored in the same folder only leads to confusion later on. 6.Navigate to where you would like this project to be created. NOTE: You are not saving the project at this point! You are creating a folder on the hard drive that your project will get saved into later. This will be explained very shortly. 7.Click “Create” on the PC or “New Folder” on the Mac to create a new folder for your project. 8.Give your new folder a name. If your are going to name your project “My First Project” then you could call this folder “My First Project” or “First Project”. What’s important here is that you are creating a folder on the hard drive to store your project into it. This folder should have a unique name that is different than any other Cubase Essential project you have created before. 9.Click “OK” on the PC or “Create” on the Mac. Your project folder is now created on the hard drive! 10.Now click “OK” on the PC or “Choose” on the Mac. 11.You should be looking at your very first project in Cu- base Essential now, Congratulations! If you look at the top of the window in Cubase Essential (called the Project window) you’ll see the name of this project is “Untitled1”. Proceed further to learn how to save your first project. !You’re not done yet! So far we’ve created a blank Cubase Essential project. We have a folder sitting on the hard drive but we haven’t saved the actual Cubase Essential project yet. The name of the project
25 Tutorial 1: Recording audio To save a project 1.Select “Save As…” from the File menu. The difference between Save and Save As are discussed in the chapter “File Handling” in the Operation Manual. 2.You will notice that Cubase Essential is in the “My First Project” folder that you created earlier. This is where you want to save your project. Type in a name for your Project – you can use “My First Cubase Essential Project” for example. 3.Click “Save” – and that’s it! To close a project 1.Make sure the Project window is selected. The Project window is the main window that you work in. See the chap- ter “The Project window” in the Operation Manual. 2.Select “Close” from the “File” Menu. If you have made any changes to the project since you last saved it, you will be prompted to “Save”, “Don’t Save” or “Cancel”. Click “Save” if you want your changes saved. To open a project Now that we have saved and closed your project, let’s show you how to open it. Open a project using the “Open” command 1.Select “Open” from the “File” Menu. Here you can navigate to the folder that has the project you wish to open. 2.Once you have found the project click “Open” and the project will load. Open a project using the “Recent Projects” submenu Cubase Essential remembers recently open projects and lists them in the “Recent Projects” submenu under the “File” menu. 1.Select “Recent Projects” from the “File” Menu. 2.Choose the project you wish to open by clicking once on it. Setting up the VST Connections The VST Connections window allows you to set up the in- put and output signals of Cubase Essential to your audio card. Cubase Essential calls these “busses”. This section will show you how to set the busses up so that you can get playback and recording working. Make sure you read the chapters “System requirements and installation” on page 8 and “Setting up your system” on page 13, so that your audio hardware is properly setup before proceeding. ÖNote that the Tutorial projects are not installed by de- fault during the installation of Cubase Essential. You will find the Tutorial Projects on the program DVD, in the folder “Additional Content”. Adding outputs 1.Open the “Devices” menu and choose “VST Connec- tions”. The default key command for this is [F4]. You’ll see several tabs at the top of the window. We’re only going to cover Input and Output right now. See the chapter “VST Connections” in the Operation Manual for more details. 2.Let’s choose “Output” first. We want to start from scratch and remove anything that is currently there, just in case it’s set up incorrectly. If you see anything in the “Bus Name” column, right-click with the mouse and choose “Remove Bus”. !Load the project called “VST Connections” found in the “Tutorial 1” folder.
26 Tutorial 1: Recording audio 3.Now click the “Add Bus” button. Choose “Stereo” for configuration and “1” for count and click OK. This has now added a new stereo bus (Left and Right) allowing us to have audio in Cubase Essential route to our audio hardware. 4.Since we mainly listen to our music as a stereo mix, all we need is a stereo output. 5.Depending on your audio hardware, your outputs should be setup now. You can however select the outputs of your choice from the “Device Port” pull down menu. Normally you’ll want to choose “Out 1” and “Out 2” or “Left 1” and “Right 2” as these are the main stereo outputs of your audio card. More sophisti- cated setups may require you to choose different outputs and even add more busses. Adding Inputs Now let’s open the “Input” tab and set up the inputs we are going to use for recording into Cubase Essential. 1.Do the same as mentioned above for the outputs. Right-click and select “Remove Bus”. 2.Click the “Add Bus” button. Choose “Stereo” for con- figuration and “1” for count and click “OK”. This has now added a new stereo bus (Left and Right) allowing us to have audio from our audio card’s input route to Cubase Essential for re- cording. Having a stereo input is useful for recording audio with two channels. An example of this is recording a keyboard with a left and right audio channel. If we wanted to record in mono or with one channel we can make separate bus- ses. Let’s do this now. 1.Click the “Add Bus” button. Choose “Mono” for con- figuration and “2” for count and click “OK”. This has now added two new mono busses allowing us to have audio from our audio card’s input route to Cubase Essential for recording. 2.Next, click in the “Device Port” column to select the audio inputs of your audio card for the stereo and mono inputs. In our case we have the MI4 interface so we are selecting “MI4 Channel A” and “MI4 Channel B” for our inputs. That’s it! You should now be ready to record audio in Cu- base Essential and then play it back. Level settings and recording For this section, we are going to record a bass guitar in mono from the input “Mono In”. Make sure you have your audio card set up and you have read through the section “Setting up the VST Connections” on page 25. Adding a mono track 1.Now let’s add an audio track to record to. Open the Project menu and choose “Audio” from the “Add Track” submenu. 2.Choose “Mono” for Configuration and “1” for Count. Click “OK”. This adds a mono audio track to our Project window. !Load the project called “Recording” found in the “Tutorial 1” folder.
27 Tutorial 1: Recording audio 3.Click on the new track you’ve created and make sure the Inspector is shown. The Inspector allows us to see and manipulate a lot of information for the selected track. 4.Make sure that “Mono In” is selected for the audio track’s input and that “Stereo Out” is selected for the au- dio tracks output. You may have different inputs and outputs based on your audio hardware. See the chapter “VST Connections” in the Operation Manual for more de- tailed information. By setting “Mono In”, we will be able to record the audio from the left input of our audio card into a track in Cubase Essential. Set- ting the output to “Stereo Out” allows us to hear what we are recording. Turning on the metronome click We’ll want to have a click or metronome play in the back- ground as we record the bass guitar so that what we record aligns with the bars and beats in Cubase Essential. 1.Activate the “Metronome/Click” button on the Trans- port panel. 2.If you would like a two bar count in before you record, also activate the “Precount/Click” button. 3.We now need to set the speed or the tempo of our project. This will directly affect how fast the click plays. You can set the tempo just below the click. In this picture, we have a setting of 125, which means 125 bpm (beats per minute). Setting levels We have a bass guitar playing through an amplifier with a microphone in front of the amplifier’s speaker. This micro- phone is plugged directly into the Steinberg MI|4 micro- phone input. We have set the level on the MI|4 so that we have enough volume without clipping. 1.Clicking the Monitor button will allow us to hear the bass guitar. You should see and hear the audio coming in to the right of the track. The Inspector Click to open the Inspector Audio coming into this track
28 Tutorial 1: Recording audio 2.Now click the “Record Enable” button on the track. Setting the track to Record Enable lets Cubase Essential know that you want to record on this track and no other one. You can have many tracks Record Enabled at a time. 3.In the Inspector, open the “Channel” tab. This will display the channel fader for the selected track. Do the best you can to send the maximum amount of volume to the audio inputs of your audio card before you hear any distortion. Most audio cards show some kind of level or volume indication. If yours doesn’t, don’t worry, we can change the amount here. 4.Move the fader up or down so that the volume is loud enough without going into the red on the channel meter. If you go into the red you may cause clipping or distortion. You will see a line near the top of the channel meter – make sure the level does not go over this line!Once the level is set, you are ready to record! Recording bass guitar 1.Position the cursor at the beginning of the project. This will make sure we start recording on bar 1. 2.Click the Record button to record the bass guitar. Since the “Precount/Click” button is activated, we’ll hear two bars of click before recording begins. 3.Click “Stop” when you are finished. 4.Turn off the Monitor and Record Enable buttons on the track so that we don’t hear the input or record on the track any more. Congratulations! You have just recorded your first piece of audio in Cubase Essential. Move ahead to the next section to learn how to play back audio. Click here to display the channel fader. Do not allow the audio level to go past this line! This is the safe area for recording
29 Tutorial 1: Recording audio Playback We are going to learn how to play back audio in Cubase Essential. You might think this is very simple – just hit “Play”. It is actually this simple but there are a few tricks to learn so that you’ll be playing back what you want with precision. To start playback There are a few ways you can play back in Cubase Essen- tial. Click the “Start” button on the Transport panel. Press the space bar on your computer keyboard. This toggles between start and stop. Press the [Enter] key of the numerical computer keypad. Double-click in the lower half of the ruler.Select the audio event called “Audio 01_01” and choose “Loop Selection” from the Transport menu. To stop playback Click the “Stop” button on the Transport panel. Clicking the “Stop” button twice moves the cursor to the position in the project where you started playback. Press the space bar on your computer keyboard. This toggles between stop and start. Press the “0” key of the numerical computer keypad. Cycle playback Cubase Essential has the ability to loop or cycle a section of your project. To set the cycle location you need to use the left and right locator. 1.On the Transport panel, set the left locator to “1” and the right locator to “5”. This tells Cubase Essential that we want to loop or cycle between bars 1 and 5. Meaning we will have a 4 bar loop since the end of bar 4 is the be- ginning of bar 5. 2.Make sure that the “Cycle” button is activated. 3.Click the Start button on the Transport panel and Cu- base Essential will play looping over and over until you click “Stop”. !Load the project called “Playback” found in the “Tutorial 1” folder. Double-click in the lower half of the ruler… … to start playback !The default key command for this is [Shift]+[G]. This is the quickest way to loop an audio event and start playback! !Don’t forget – you can set the locators to encom- pass the selected event, turn on “Cycle” and begin playback all by the key command [Shift]+[G]. The left locator set to “1”. The right locator set to “5”. Cycle activated.
30 Tutorial 1: Recording audio Recording modes with cycle off There are three different modes for recording when the cycle is turned off. This is called linear recording. The three modes are: Normal Merge Replace When recording audio, “Normal” and “Merge” are the same. Selecting either of these will allow you to record over the top of another audio event and it will appear as an overlap. You can then select between the overlapping events and determine which one will play. This is dis- cussed in the section “Cycle recording” on page 30. “Replace” mode when used will not overlap the audio if there is already some on the track. It will split or cut the audio where the recording takes place replacing what was there previously. Keep in mind though that the audio being replaced is not permanently deleted. It is only cut or trimmed away allowing you to recover it later. Cycle recording You can record audio while “cycle” is on. So far we’ve shown you how to add tracks, record and playback. Now we are going to add an electric guitar to our bass guitar using cycle recording. Recording with cy- cle on allows us to make multiple passes of our recording and then pick the best take. If you haven’t reviewed the previous sections in this tuto- rial, please do as we are going to move a little faster now. Recording electric guitar 1.Let’s add another “Mono” audio track. 2.You can see now that we have a track called “Audio 01” and “Audio 02”. Up to now we haven’t been con- cerned about naming the tracks but let’s do this now. 3.Double-click on “Audio 01” and re-name it “Bass”. 4.Double-click on “Audio 02” and re-name it “Elec Gui- tar”. That looks a lot better now. It’s always good to name your tracks before you start to record. This way the audio event will take the name of the track. Since “Audio 01” was the name of our first track the audio event is named “Audio 01_01”. The suffix “_01” be- ing the first event recorded on the “Audio 01” track. We’ll show you how to re-name your audio files in the chapter “Tutorial 2: Editing audio” on page 32. !Load the project called “Cycle Recording” found in the “Tutorial 1” folder.
