DD8
plus Version 2.20 - September 1998
NOTE 2: If two mono recordings are assigned to a stereo pair, it will not be phase coherent on
the DD1000.
When recording on the DD8 is finished, the DD8 stores extra cuts files and record settings to
allow this backwards compatibility.
You will also note the way DD1000 take names are created by the DD8. The ten-character take
names are formed as follows:
A
The first four characters are the recording name
B
These show the track number the recording was made on
C
This is a unique identifier to create a totally unique take name
MULTIPLE DISK DRIVE SYSTEMS
The DD8 works with multiple disk drives very differently from the DD1000 (much better in fact!).
A problem with the DD1000 was that you had to make sure that a disk was in its original drive
before it would playback properly. This is because the SCSI ID is a part of the Qlist cue. For
example, if a cue is specified to play from drive ID#3 but the disk is placed in drive ID#5, it will not
play.
The DD8 uses a method based on each disk’s unique label. This means that the DD8 ‘learns’ the
actual SCSI ID when the project is loaded. Therefore, a disk can be placed in any drive and the
project will still playback correctly regardless of the SCSI IDs the drives may be. The following
illustrates the difference between the two methods.
A cue in a DD1000 Qlist says:
“Play [TAKE N] from the disk in the drive with the SCSI ID#X”
If it can find that take on the disk in the drive with ID#X, it will play the cue. If it doesn’t find that
cue on the disk in drive #X, it will not play it. Neither will it try to look for it on another drive
because it is specifically looking for it on that ID and no other.
The DD8, however, says:
“Play [TAKE N] from the disk with the unique label #XXXXXXXX”
DD1000 disks, however, do not have the concept of disk labels and so to overcome this, the
DD8 will automatically write a label to the DD1000 disk, thereby giving it something it can work
from given the above statement. In this way, it doesn’t matter which drive the disk is in - the DD8
is looking for the disk label, not the SCSI ID. It will find this and so it will playback correctly
regardless of the drive the disk is in.
NOTE: Please note that for the label to be written to the DD1000 disk, the write protect switch
must be off. If the disk is write protected, the label can’t be written. In this case, the DD8 uses
the same logic as the DD1000 (i.e. Play [TAKE N] from the disk in the drive with the SCSI
ID#X) and you will have to make sure that the disk is in the correct drive.
Furthermore, if a DD1000 Qlist has audio that exists on one disk only (as is invariably the case),
the DD8 assumes that the audio is on the same disk as the Qlist and so it will also playback
properly.
