See Dee
+ (pronounced "seedy plus") is a method used to format an audio CD so that it carries ROM data as well as audio. Only Ubu Projex uses the name "see dee
+." We do this because we are difficult so-and-so's and we refuse to change with the times. The method is also called "CD Extra" which is the Sony initiative or "Multisession" which is the technical description.
Note: The term "CD Plus" is evidently a
trademark of a chain of CD retail stores in Canada. It should not be used as
a term to refer to Enhanced CD music CD-ROMs.
"Enhanced CD" is
a generic term that covers both Multisession and Active
Audio format methods. Be aware that all these names are loosely used, and often interchanged. It's confusing.
Multisession (See Dee +, or CD Extra) is the more "elegant" solution but the method requires significantly more physical space on the disk to accomplish the session segregation, almost 90 meg more than Active Audio. This is not a consumer concern. There is no chance of an audio player accessing the digital information, which, conversely, is a consumer concern. The rom drive hardware must be physically capable of reading the disk and the software drivers need to be reasonably up-to-date.
Active Audio is also known as the Pre-Gap or Hidden method because it "hides" the ROM data in Track 0 of the disk. Since audio
cd players look to Track 1 for their first read they skip the ROM data. It's a clever solution but if you mess with the REW or FF
buttons long and hard enough you might be able to access the digital information with your cd audio player. This is not a
Good Idea. The ROM drive hardware must be physically capable of reading the disk and the software drivers need to be reasonably up-to-date.
In the Wintel World lots of computers came with ROM drives that are hardware-incapable of reading either multisession or active audio disks. Others are capable of active audio reads but not multisession. Roughly the same proportion are vice-versa incapable. In the Apple World things are much better. As per. We have provided a Tech Checklist to step though the process of determining what's what in your life.
Pere Ubu's FOLLY OF YOUTH SEE DEE
+ and BEACH BOYS SEE DEE + are multisession disks. The first pressings of EREWHON by David Thomas and two pale boys are active audio. Later pressings will be multisession. For an explanation you need to go elsewhere.

Is your CD-ROM drive hardware-capable of reading multisession or active audio disks? This is the place to start.
Mac Users: The answer is straightforward with Apple ROM drives. Even then issues arise with certain configurations. If you don't have an Apple ROM drive or you aren't using Apple CD-ROM Software then you've got to do some investigation.
Wintel Users: Though most recently manufactured CD-ROM drives can read Enhanced CD disks with the proper software drivers, many
older models can't, period. Others require an
update to their firmware.
It's been estimated that up to 50% of existing wintel CD-ROM drives can't read
Enhanced CD disks. Sony Online's
CD Extra pages provide a
helpful list of
multisession compatible drives as well as a list of
technical support contacts for ROM drive manufacturers.
NOTE! Corel offers an excellent and free Windows program called "Music Advisor" that tells you if
your drive can read multisession or active audio disks. It's about 90K zipped. Start with this. The site is also useful for
a detailed overview and for troubleshooting specifics.
Is the interface between your computer and your ROM drive functioning properly?
Mac users: With external drives make sure that the SCSI chain is properly connected and terminated. Read the <gasp> manual. There's a certain amount of voodoo attached to scsi chains. In the Reference section of FWB's Software And Support Resources page is a page of links to information and tips concerning SCSI.
Windows users: With a SCSI interface make sure you have the latest software drivers and that those drivers support multisession or active audio. The Corel Music Adviser page is a good source of interface related information for pcs.
Is the software driver that your computer uses to address your rom drive up to
date & capable?
Mac Users:Use the latest version of Apple CD-ROM Software.
Wintel users: Contact the manufacturer for an update or search the usual online sources. Have fun. Sony provides a list of contacts.
Is the driver properly installed? Read your Windows User's Guide, pages 179-181, 557-560, 567. Win95 users aren't supposed to have these problems.
In the Windows 95 HCL, Microsoft recommends looking for drivers in these places:
Runtime versions of Quicktime for both Mac and Windows are supplied
on the See Dee + discs. Newer versions of the Quicktime software can be
obtained from
Apple's Quicktime Web site or
any of the many the Apple
Software Update archives. The most recent release versions of
Quicktime for Macs is version 2.5; for Windows it is version 2.1.2. Note that
there are separate versions for Windows 3.1 (16 bit) and Windows 95/NT (32 bit).
Users of both platforms are strongly advised to upgrade to the latest
version as the new versions of the software fix a number of bugs.
Windows users should check out Bob Currier's "A Windows User's Guide to QuickTime" (which Bob
has generously consented to let us carry on this site). Although some of
Bob's information is specific to Compuserve he provides lots of info which
will be useful to anyone using Quicktime on a Wintel machine.
One of the features that sets see dee + apart from earlier "mixed
mode" CD formats is that audio CD players should ignore the data tracks and
go straight to the first music track. However, a few (particularly older)
audio CD players may not bypass the computer data but will try to "play"
it. While it's very unlikely your audio cd player will do this, to be on
the safe side keep the volume low until you know for sure as this digital
noise could damage your speakers if played at high volume. Also be aware that if you mess around long
& hard enough with the rewind or fast forward you might just get into
Digital Noise Land.
A recent report noted that some audio cd players cannot skip the Active Audio partition of the EREWHON disk and count down in silence until the ROM data is passed. We lost the email with the specific affected models but are hoping to retrieve it.
If you have a Macintosh with any version of Apple's 300 or 600 series or newer
CD-ROM drives (internal or external) to access see dee + all you will
need is the latest version of Apple CD-ROM Software. (Older Apple
drives such as the PowerCD, the CD SC and the CD 150 are not
multisession capable.) The current version of Apple CD-ROM Software is
5.3.2 and it fixes several bugs and "includes improved support
for CD Extra discs" (for more details on this and other fixes read Apple's description).
The CD-ROM software is free and is available from any of the many the Apple
Software Update archives:
via
the Web (select "keyword search" enter "CD-ROM" in the search form)
or ask your local Apple Dealer or Mac Users Group or call Apple.
The software comes as a disk image. You will need to mount the disk image with Shrinkwrap. This creates a virtual floppy disk on which
you'll
find an installer. Shrinkwrap is a fine product which is still freeware for non-commercial use.
The Apple CD-ROM software is also available on some online services:
FWB's Software And Support Resources page shows which of the many drive models they
suppport are capable of playing Enhanced CDs (and also has a lot of other
potentially useful technical information about the quirks and capabilities
of many drives).
If you are running FWB's CD-ROM Toolkit you will need version 1.5.6 or
better to play See Dee + disks. A recent report noted that v2.0.3 needed updating to 2.0.5 to satisfy an 8500. If you need to update your copy of CD-ROM Toolkit check out
the the Software Information and
Updaters page at the FWB Web site or
send email to upgrade@fwb.com.
Multisession: Open the control panel, click on options and
then make sure that you enable the feature called "Upon CD inserts check every track for possible data to mount."
Active Audio: Open the control panel, click on options and
then make sure that you disable the feature called "Upon CD inserts check every track for possible data to mount." Otherwise the disk will mount as a plain audio CD.
Apple Quad Speed CD-ROM Drives
There is a known problem with playing See Dee Plus disks on early
versions of the AppleCD 600 quad-speed drive manufactured by Matshushita
(you can use a utility such as Robert Polic's freeware SCSI Probe or FWB's
HDT Prober to determine the manufacturer of your AppleCD 600). Some of
these drives had the wrong ROM installed when they were manufactured. This
ROM did not allow the drive to read multi-session data CD-ROM disks. If
you are having problems reading multi-session CD-ROM disks, an authorized
Apple service provider can replace the drive. AppleCD 600 quad-speed
drives maufactured by Sony always worked properly with multi-session CD-ROM
disks.
Corel Drivers and CD-ROM Setup
The "Corel Drivers for Enhanced CD" that come with the Bob
Dylan's Greatest Hits Volume 3 and some other Sony CD Extra products are
intended for non-Apple CD-ROM drives. The Corel CD contains a multimedia
update, which is the Apple Multimedia Tuner used prior to QuickTime 2.1 to
fix some problems in older versions of QuickTime, and is unrelated to See
Dee Plus disks. The multimedia update should not be installed (if you're
using a version of Quicktime older than version 2.1 you should upgrade- see
the Quicktime Software section for more info).
The Corel CD also contains Apple's CD-ROM Setup 5.1.1. This driver should
also not be used, and instead you should get CD-ROM Setup 5.1.7 from the
Apple SW Updates archive (see above).
The information in notes 4 and 5 is from volume 2,
issue 18 of the Apple
Information Alley Newsletter, which is an excellent source for all
sorts of obscure but useful technical information about Apple products.
1. Multisession disks may take somewhat longer to
mount than regular CD-ROMs. If you put a See Dee Plus disk in your drive and
nothing happens right away, don't panic. Wait times of up to 40 seconds
have been reported though this seems excessive and may be indicative of a
system that needs tweaking.
2. Data bottlenecks can occur where the sound card also serves as the CD-ROM interface, particularly when dealing with 16-bit sound. Consider a scsi interface.
3. Built-in CD-ROM drives in new pcs
that come with Windows 95 preloaded SHOULD play multisession right out of the box.
Microsoft's Win 95 See Dee Plus Info Site
has info about hardware and software compatibility. I suggest bothering them. See our Quicktime Software
section for info on Quicktime for Windows and our CD-ROM
Drives section for more info on hardware compatability.
4. Sometimes confused Wintel users overwrite Win95 drivers with Windows 3 drivers. We're not
saying you're one of these people. Just stating a fact. If Win95 won't run see dee
+ then bother Microsoft. It's supposed to and they should help you make it work.
If you had problems getting your machine to read the See Dee + and
then solved the problem yourself please email us or use this form to let us
have the details so we can add to the tech support page and help others
(include all relevant information about your hardware and
software and what you did to make it work):
Note- These forms are only for
communications regarding Pere Ubu's Folly of Youth and Beeboys See
Dees +. If you have general questions or comments for Pere Ubu or
Ubu Web please use one of the forms on the Contacts & Feedback page.
The soundtrack to the Fish Shack qt is digitially cruddy. This doesn't
show when played thru the computer's speaker (which is why I never caught
it) but if you listen on headphones, uh... There may be other such
problems involving sound but I'm too distressed to look. You didn't want
hi fi from a computer anyway, did you? (Silly boy).
Please note the following:
The thing works.
It's a new format, you need current drivers or extensions.
Please do read the READ ME files.
If you run a computer you need to figure stuff out.
Many files included are DATA files. They don't DO anything.
On the Mac three icons will appear on your desktop (all of which need
to be trashed to eject the disk). They are called "Audio CD,"
"FOY" and "FOY_PC." "Audio CD" contains the
4 audio tracks. You can manipulate these with Quicktime. "FOY"
will open a window. This is the Mac side. "FOY_PC" is the
Windows side. There are some different data files spread around the pc
side you might want to access so I made it available to the Mac side.
On the PC you can only access "FOY_PC."
Make sure you remove old versions of updated software. For example,
the Apple Installer puts the new Apple CD Audio Player in the Apple Menu
Items folder, if you don't keep the old one there you'll need to search
& delete.
WINDOWS ONLY: Clicking the Tour icon (blue car) on the Story of My Life
page of the discography takes you to the Imago promo cds screen and there's
no way out except using the scape key or CONTROL-Q to quit.
I failed to convert the QTWDOC.TXT correctly when I transferred
from the Mac. My abject apologies. It's a useful document. A more
readable copy is available here on the web site (see the Quicktime Software section) or it can be
downloaded from GO MACMEDIA on Compuserve.
Some button & sounds may not run properly or may cause havoc while
Quicktimes are running because of the limitations of the Windows sound
drivers. Didn't see this in the testing and there are no reports but be
aware.
The new version of Quicktime for Windows (2.1.2 ) is available at
the usual download sites and you should definitely switch to it (the
version included on the Beeboys disc is 2.0.3).
