12. Operation under ASIO 2.0
12.1 General
At the time of writing, Cubase VST is the only available ASIO 2.0 application, so it will be used
as an example throughout this chapter.
Start the ASIO software and
select 'System' from the Audio
menu.
Select
'Hammerfall
ASIO' as 'ASIO Device'. The
button 'ASIO Device Control
Panel'
opens
DIGI9636 Settings dialog
(see chapter 9, Configuration).
DIGI9636
also
simultaneous
record
playback of S/PDIF audio data
together
with
record
playback in ADAT format.
Please note that the external
S/PDIF devices have to be
running in sync, otherwise
recordings will be corrupted.
Enhanced ZLM (Zero Latency Monitoring) in the DIGI9636 is so efficient that even
different sample rates would usually cause no noticeable clicks or other unwanted noises.
Having said this, you should not be tempted to 'misuse' this feature, because Murphy's Law
is sure to ruin your 'take of the century'.
DIGI9636 supports 'ASIO Direct Monitoring'. Please note that in this mode neither routing
nor pan are supported so the input signals will only be routed to the same output channel. Other
VST mixer settings have no effect.
When the sample frequency is set to 88.2 or 96 kHz, all the ADAT optical inputs and outputs
operate in Sample Split mode, so the number of available channels is reduced from 16 to 8.
Some programs have problems to reset the ASIO driver properly. To change the number of
ASIO channels it can be neccessary to restart the program for the change to take effect.
12.2 Performance
The 'Audio Performance' settings are especially important. Firstly, the number of channels
should be changed from 8 to 26 so that all the DIGI9636 inputs can be accessed.
A very common problem is insufficient hard disk perfor-
mance. If the first track is missing while recording multiple
tracks, or the error message 'Audio: Record Error' appears,
the disk sub-system is too slow i.e. it is unable to write the
audio data to the disk quickly enough. The problem can
almost always be remedied by changing 'Disk Block Buffer
Size' from the default 64kB to 256kB.
