This is especially true if you want to record more than 12 tracks at the same time. 26 tracks are
only possible after changing ‘Disk Block Buffer Size’ to 256kB (depending on your computer).
Please note that these parameters are only updated after clicking on ‘Apply’.
The heyday of (expensive) SCSI hard disks in high-speed audio workstations is over. Today’s
cheap high-capacity EIDE disks allow continuous transfer rates of well over 5 MB per second.
In practical terms, this is more than enough to record up to 24 simultaneous tracks using
Cubase and
Hammerfall
!
The Buffer Size value in
Hammerfall
’s Settings dialog determines the latency (in this case
the delay) between the audio application and the
DIGI9652
as well as general system
stability. The higher the value, the more tracks can be recorded and played back
simultaneously and the longer the system takes to react. At the given maximum of about 0.2
seconds, you will not notice much delay at all - the system will still respond quickly and
smoothly.
13.3 Synchronization
To achieve sample-
accuracy between the ADAT
recorder and
Hammerfall
while
running Cubase, connect
the ADAT sync output with
the 9-pin D-type sync input
of the
DIGI9652
. The
‘Time Code’ field in the
Settings dialog should now
show the same time
information as the ADAT
recorder.
Double-clicking on the Sync
button in Cubase' transport panel will open the ‘Synchronization’ dialog. Select ASIO 2.0 as the
timecode base (under Sync Source), confirm the dialog with ‘OK’, then activate Sync mode by
(single) clicking on the Sync button.
If synchronization is not working i.e. Cubase does not respond when the ADAT is set to ‘Play’,
please try the following:
•
Check the cables
•
Switch Sync off and on again (in Cubase’ transport panel)
•
Select ‘Reset Devices’ from the Options menu.
•
Switch on the ADAT recorder(s) before starting Cubase
•
Use the BRC as Master and send its word clock to all other devices
