13. Operation under ASIO 2.0
13.1 General
We will use Steinberg's Cubase VST as an example throughout this chapter. All information
provided can easily be adaptated to other programs.
Start the ASIO software
and select 'System' from
the Audio menu. Select
'ASIO DIGI9636/52' as the
audio
I/O
device.
The
'ASIO
system
control'
button
opens
the
Hammerfall's
Settings
dialog
(see
chapter
9,
Configuration).
Hammerfall
also
allows
simultaneous record and
playback of SPDIF audio
data together with record
and playback in ADAT
format. Please note that
the
external
SPDIF
devices have to be running
in
sync,
otherwise
recordings
will
be
corrupted.
Project Hammerfall supports 'ASIO Direct Monitoring'. Please note that in this mode neither
routing nor pan are supported. Therefore the input signals will only be routed to the same
output channel. Other VST mixer settings have no effect. Additionally, as the Hammerfall has
no internal digital mixer, the playback signal of the ADM channel will be replaced by the record
signal.
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 24 to 12.
13.2 Performance
The 'Audio Performance' settings are especially important. Firstly, the number of channels
should be changed from 8 to 26 so that all the Hammerfall's 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.
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'.
