It often makes sense to monitor the input signal or send it directly to the output. This can be
done at zero latency using
TotalMix (see chapter 24).
An
automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol
with our ASIO drivers and all ASIO 2 compatible programs. When 'ASIO Direct Monitoring' has
been switched on, the input signal is routed in real-time to the output whenever a recording is
started (punch-in).
13. Operation under ASIO
13.1 General
Start the ASIO software and
select
ASIO Hammerfall
DSP as the audio I/O de-
vice. The 'ASIO system
control' button opens the
HDSPe Settings dialog (see
chapter 11, Configuration).
13.2 Channel Count under ASIO
At a sample rate of 88.2 or 96 kHz, the ADAT optical input and outputs operate in S/MUX mode,
so the number of available channels per port is reduced from 8 to 4.
At a sample rate of 176.4 and 192 kHz, the ADAT optical input and outputs operate in S/MUX4
mode, so the number of available channels per port is limited to 2.
Please note that when changing the sample rate range between Single, Double and Quad
Speed the number of channels presented from the ASIO driver will change too. As some chan-
nels are removed, SPDIF and AES move up in the list. This may require a reset of the I/O list in
the audio software, and will require a reassignment of the channels within the project.
