mlcd.addendum.book Page 1 Wednesday, June 27, 2001 3:51 PM chapter 1 MasterList CD 2.4 System Requirements MasterList CD 2.4 requires: • A Digidesign-qualified PCI-based Power Macintosh G3 or G4 is recommended for best compatibility with currently shipping CD recorders. New Features in MLCD 2.4 New CD Recorders Supported MasterList CD 2.4 adds support for the following CD recorders: • 8 MB of application RAM. CD Recorder Firmware • Mac OS version 9.0.4 (9.1 recommended).
mlcd.addendum.book Page 2 Wednesday, June 27, 2001 3:51 PM Plextor and Burn-Proof The Plextor PX12/10/32S has a Burn-Proof feature to help minimize buffer underrun errors. If a buffer-underrun error is about to occur, BurnProof turns off the laser until the buffers fill with data and resume writing. When used with the Plextor PX-12/10/32S, MLCD 2.4 lets you engage or disengage BurnProof writing from the Write Compact Disc dialog. New Features in MLCD 2.3 New CD Recorders Supported MasterList CD 2.

mlcd.addendum.book Page 5 Wednesday, June 27, 2001 3:51 PM chapter 2 Additions to the MasterList CD User Guide This chapter documents topics not covered in the MasterList CD 2.0 User Guide. MLCD with Digidesign Audio Hardware When using MasterList CD with supported Digidesign audio hardware, you can configure audio playback to be routed through your Digidesign system for higher fidelity output, monitoring, or digital output.
mlcd.addendum.book Page 6 Wednesday, June 27, 2001 3:51 PM CD Recorders For important usage details specific to your CD recorder, refer to Chapter 4, “CD Recorder Information”. Disc Write Speed With the optimization of CD recorders for writing at higher speeds, 1x and 2x write speeds can exhibit write errors that were not seen in previous, slower, models. Digidesign recommends that you write CDs at the highest speed that your system will allow.
mlcd.addendum.book Page 7 Wednesday, June 27, 2001 3:51 PM Adaptec Toast Software Copying Tracks with Index Points 2–99 There is a known conflict between MasterList CD and the Toast CD Reader extension. To avoid this conflict when using MasterList CD, remove the Toast CD Reader extension from the Extensions folder (inside the System Folder) and restart your computer.
mlcd.addendum.book Page 8 Wednesday, June 27, 2001 3:51 PM Editing in the PQ Window Editing in the MasterList window affects how your CD will sound and editing in the PQ window affects how your CD will look to a CD player. For this reason, and because certain timing edits performed in one window can affect timings in the other window, it is suggested that you not perform any edits in the PQ window until your MasterList plays through exactly the way you want your finished CD to sound.
mlcd.addendum.book Page 9 Wednesday, June 27, 2001 3:51 PM MasterList CD Menu Commands Renamed Menu Commands Since the MasterList CD User’s Guide was written, all commands that used the term “Soundfile” in the MasterList CD menus have been changed to read “Item.” For example, Add Soundfile is now Add Item. The operation of these renamed commands is unchanged.

mlcd.addendum.book Page 11 Wednesday, June 27, 2001 3:51 PM chapter 3 Successful CD Writing This chapter documents the essential rules and guidelines for successful CD writing with MasterList CD and your particular CD recorder. It covers details on what is required to ensure the creation of a professional quality CD, whether it be for use as a CD master or as a reference disc.
mlcd.addendum.book Page 12 Wednesday, June 27, 2001 3:51 PM What are E32 errors? E32 errors are “uncorrectable” read-data errors. All CD readers contain error correction circuitry within their read mechanisms. This circuitry is two step. Occurrence of an error is initially dealt with by the first level of error correction circuitry. If this error is not corrected, it is then processed by the second level of error correction. Only two errors can be dealt with by each level at one time.
mlcd.addendum.book Page 13 Wednesday, June 27, 2001 3:51 PM Currently MasterList CD will produce a warning dialog if the CD recorder signals that a fatal error has occurred, such as a servo error, focusing error, buffer underrun, a disc tracking problem, or insufficient media capacity. Overall, it is currently not possible to guarantee the quality of a disc as it is being written, but by following the rules outlined below, you can be assured of the highest success rate possible.
mlcd.addendum.book Page 14 Wednesday, June 27, 2001 3:51 PM An Explanation of the Four Basic Rules Write Disc Using 2x or 4x Real-Time Write Speed It is a fact that faster disc rotation increases the quality of the data writing to disc. Tests have shown that error rates are much higher on discs that are recorded at 1x real-time speed compared to those written at 2x and 4x.
mlcd.addendum.book Page 15 Wednesday, June 27, 2001 3:51 PM lost. However, the CD player is expecting to see this data, and when it is not present, it is interpreted as a burst of uncorrectable read errors, (E32s). While many CD players are able to skip over those “corrupted” areas with no audible effect, the CD readers at the duplication facility are more likely to interpret these areas as read errors, (E32s).
mlcd.addendum.book Page 16 Wednesday, June 27, 2001 3:51 PM CD Caddies Index 0 Considerations CD recorders typically come in one of two varieties: tray loading or caddy loading. Each type requires proper care and maintenance to avoid problems during disc writing. For CD caddyloading mechanisms, it is a good idea to blow the inside of the caddy out with compressed air before using it. Many manufacturers now recommend that you actually replace the CD caddy with a brand new one every six months or so.
mlcd.addendum.book Page 17 Wednesday, June 27, 2001 3:51 PM Index 1 Considerations End Access Point Index 1 is supposed to indicate the start of the program material, (i.e. audio) in a track. MasterList CD by default locates the Index 1 at the beginning of the MasterList item, (if the sound file, region or playlist represents one track, or is the first item in that track). However, MasterList CD does not intuitively know where the audio starts within the item.
mlcd.addendum.book Page 18 Wednesday, June 27, 2001 3:51 PM exist at the end of a track. If the track’s audio ends exactly on the End Access Point, the CD player may mute it’s audio outputs and skips to the next track slightly prematurely, and the end of the track will be cut off. Specifying a Begin and End Access Point Offset allows the CD player’s audio outputs to completely unmute and mute respectively before the track’s audio starts and ends.
mlcd.addendum.book Page 19 Wednesday, June 27, 2001 3:51 PM to update your MasterList CD document if necessary. Alternatively, include additional space between each item in the MasterList and edit the subcode points to conform to the requirements of the CD player. First Track Start Time It is often customary to add about a second of silence to the start of the first track on a CD.
mlcd.addendum.book Page 20 Wednesday, June 27, 2001 3:51 PM The adjustment is made to the MasterList when you attempt to write a CD, DDP tape or Image file. The following dialog will appear informing you that an adjustment to the first item start time, if necessary, is in progress.
mlcd.addendum.book Page 21 Wednesday, June 27, 2001 3:51 PM 4 With overlapping crossfades, by default the incoming track start is positioned in the middle of the crossfade. If these two items represent two CD tracks, then the number displayed on your CD player will change halfway through the crossfade, unless the track start time of the incoming item is edited. To change this requires editing the track start time in the PQ subcode window.

mlcd.addendum.book Page 23 Wednesday, June 27, 2001 3:51 PM chapter 4 CD Recorder Information General Information Subcode Parameters Note that certain CD recorders differ in their restrictions on certain subcode parameters. For instance, some recorders might require fixed Index 0 lengths, or require silence-only gaps, or support a limited number of tracks.
mlcd.addendum.book Page 24 Wednesday, June 27, 2001 3:51 PM Under certain circumstances, writing a disc immediately after performing a test write will result in a disc that is still blank. Though MasterList CD will appear to be writing the disc, in actuality a test write had been performed. This is an extremely rare occurrence, and usually does not happen if the Write CD window is closed and reopened prior to writing the disc.
mlcd.addendum.book Page 25 Wednesday, June 27, 2001 3:51 PM Philips CDD-522 Due to limitations in the tested version of Philips CDD-522 firmware, support of the Copy Prohibit feature has been disabled in MasterList CD. Digidesign has found that while this unit appeared to write Copy Prohibit to disc, analysis of the resultant disc using a PQ Analyzer showed that none of the specified Copy Prohibit flags had been set.
mlcd.addendum.book Page 26 Wednesday, June 27, 2001 3:51 PM Plextor CD Recorders Index Points The maximum number of index points that can be written with the supported Plextor CD recorders is 598 (with tested firmware). Writing a disc containing the full amount of index points may not be possible at higher write speeds. Writing at lower speeds allows you to include the full 598 total index points. Always perform a disc write in Test Mode first if you are using more than 100 total index points.
mlcd.addendum.book Page 27 Wednesday, June 27, 2001 3:51 PM DIP Switch settings Ensure that the DIP switch settings are as follows: Encoder DIP Switches (Up = ON, Down = OFF) 1: Encoder: ON Teac CD Recorders ISRC Limitation Tested Teac CD recorders imprint a Drive Identification Code onto each track of a recorded disc that may inhibit the ability of some analyzers to read and display the disc’s ISRC codes.
mlcd.addendum.book Page 28 Wednesday, June 27, 2001 3:51 PM Additional Troubleshooting Absorption Control Error An absorption control error is posted when a track is finished if at any point in the track the write laser had to use full power to write. It does not indicate that an error will be on the disc at those points, but rather that there MAY be one. Buffer Underrun During disc write, the buffer of the CD recorder is constantly being fed with data via the SCSI bus.
