NOTE
You can show a simple view of the performance meter on the Transport panel and
on the Project window toolbar. These meters only feature the average and the disk
indicator.
ASIO-Guard
The ASIO-Guard allows you to shift as much processing as possible from the ASIO
realtime path to the ASIO-Guard processing path. This results in a more stable
system.
The ASIO-Guard allows you to preprocess all channels as well as VST instruments
that do not need to be calculated in realtime. This leads to less dropouts, the ability
to process more tracks or plug-ins, and the ability to use smaller buffer sizes.
ASIO-Guard Latency
High ASIO-Guard levels lead to an increased ASIO-Guard latency. When you
adjust a volume fader, for example, you will hear the parameter changes with a slight
delay. The ASIO-Guard latency, in contrast to the latency of the audio hardware, is
independant from live input.
Restrictions
The ASIO-Guard cannot be used for:
• Realtime-dependent signals
• External effects and instruments
• Plug-ins that have a different bit version than the operating system
NOTE
If you select Devices > Plug-in Manager and click Show Plug-in
Information, you can deactivate the ASIO-Guard option for selected
plug-ins.
If you activate the monitoring for an input channel, a MIDI or a VST instrument
channel, the audio channel and all dependent channels are automatically switched
from ASIO-Guard to realtime processing and vice versa. This results in a gentle
fade out and fade in of the audio channel.
Activating the ASIO-Guard
PROCEDURE
1. Select Devices > Device Setup.
2. In the Device Setup dialog, open the VST Audio System page.
