Burning Your Song to a CD via the SCSI Burner

SCSI CD Burner Limitations

The ability to connect a CD burner to your VS workstation provides a way to both create audio CDs and back up your work. However, there are some important things to understand regarding the CD burner.

First, the CD burner must have a SCSI port, and only certain brands of SCSI CD burners will work. All of the Roland-branded burners will work, but they are expensive. You can save some money by purchasing a SCSI CD burner manufactured by Plextor. All Plextor SCSI CD burners, up to the 12x10x32 model, will work with the VS-880/890 workstations. If you were considering purchasing a SCSI CD burner made by any other manufacturer, I'd recommend against it, unless you know that it is already being used by a VS workstation. The VS operating system only supports a particular list of SCSI CD burners. You can think of the operating system of your VS like the operating system found on some older computers. When you connect peripheral devices to these computers, you need to install a driver in order for the device to be recognized by the operating system. The VS is similar, except that you cannot install your own drivers; the only drivers available are those included within the operating system.

Regardless of the write speed available on the actual SCSI CD burner, the VS limits the actual write speed to a maximum of 4x. This is another reason why the older Plextor models are attractive, as most people don't want to spend hundreds of dollars for a new SCSI CD burner only to find that it can't burn faster than 4x speed.

Preparing to Burn

Before you actually burn your song to CD, there are a number of things to consider. First, your song must have been recorded using a sample rate of 44.1kHz in order for it to be burned to the SCSI CD burner. If you used a different sample rate for your song, you'll have to record the song to an external device. Also, remember that if you apply any effects or signal processing changes ”or change any track parameters such as level, pan, EQ, and so on ”these changes will not be applied during the burn.

Also know that when the song gets burned to CD, the VS assumes the song starts at 00:00:00:00. If you have blank space before your song actually starts, consider using Track Cut so that the true beginning of your song starts in the 0.2 “0.5-second range. The same principle applies to the end of your song. Figure 7.1 shows an example of using Track Cut to eliminate blank space at the beginning and end of a song.

The process of burning the song to CD requires additional space on the internal hard drive. When you perform the burn, the VS first creates a CD-R image file on the internal hard drive and then writes this image file to CD. To put this in perspective, attempting to burn a four-minute song to CD can take 10 minutes or more. The VSR-880 and VS-890 workstations provide a feature called the mastering room, which provides a simpler method for getting your song burned on CD. When you enable the mastering room function, you can bounce six tracks down to two, insert effects to the entire mix via the Master Block, and have the resulting two tracks be created in CD-R image format. Data existing on the Mastering Tracks can then be more quickly burned to CD.

When you burn your song to CD, you'll have the option of choosing Disc-At-Once (DAO) or Track-At-Once (TAO). If you are burning a single song at a time, choose TAO. TAO will place two seconds of silence after each song. If you eventually want more than one song on this CD, and you do not want a two-second gap between songs, you'll need to use DAO. If you use DAO, you'll need to have the final stereo pair of tracks for each song on the same V-Tracks within a song. This works well if you've recorded a live concert of multiple songs as a single song within the VS. However, if you had recorded multiple individual songs that you wanted to burn using DAO, you'd need to have all of these songs created as one long song in the VS. Unfortunately, the VS-880/890 workstations don't provide a function to combine multiple songs into one song. The only way to accomplish this would be to record each song to an external recording device, such as a DAT or stand-alone audio CD burner, and then record each song back-to-back into the VS within a single song. If you are using DAO, you need to place song markers at the beginning of each song. To place a song marker, hold the SONG Edit Condition button and press TAP. The VS automatically assumes a song marker at 00:00:00:00, so you only need to do this for subsequent songs.

Performing the Burn to CD

To burn your song to CD, press the SONG Edit Condition button multiple times until you see SNG CD-R Write ?, and then press YES. The VS will search for the SCSI CD burner, and it will briefly show some information about the CD burner in the display.

Next, you'll be prompted with SNG Disc at Once ? If you want to burn using DAO, press YES; otherwise press the parameter button to see the SNG Track at Once? message and press YES to burn using TAO. Well use TAO in this example; using DAO is similar. Next, you'll see the message SNG Write + Finalize? If you want to finalize the CD after this song is burned, press YES. If you want to be able to burn additional songs to this CD, press the button until you see the SNG Write w/o Fin.? message and press YES.

At this point, the display will show useful information about the size of the song you want to burn, the amount of space remaining on the hard drive, and the amount of space remaining on the CD, as shown in Figure 7.2. After reviewing the display and verifying there is enough room on the CD and hard drive to perform this operation, you're ready to select the pair of tracks to burn to CD. Press the SELECT button for the track that represents the left side of the stereo pair, press the YES button, and press the SELECT button for the track that represents the right side of the stereo pair. During this step, you cannot change which V-Track is selected for a given track. For example, if you want to burn from tracks 7-2 and 8-2, but V-Track 1 is the currently selected V-Track for tracks 7 and 8, pressing track 7s SELECT button will show 7-1 in the display, and you will not be able to select 7-2. Instead, cancel out of this procedure, select the appropriate V-Tracks, and invoke this procedure again.

After selecting the appropriate tracks, press the parameter button. You can now select the write speed for the burn. Remember, the VS can only burn at a maximum of 4x speed. After selecting the speed, press the parameter button, and when prompted with SNG CD-R Write Sure?, press YES. Youll then see a couple of additional prompts, so press YES a few times. At this point, the VS will begin converting the song to the required CD-R image file, and once that is complete, the burn to CD will begin. When the burn is completed, you will be prompted to burn another copy of the song. If you press YES, the VS will not need to convert the song, as the CD-R image file will still be available. However, once you answer NO to the Write Another? prompt, the CD-R image file gets deleted from the hard drive.
