Setting up your system
The ASIO-Guard Option
The overload indicator to the right of the disk indicator lights up, if the hard disk
does not supply data fast enough.
Try using the Disable Track function to reduce the number of tracks playing back.
If this does not help, you need a faster hard disk.
Ö 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.
The ASIO-Guard Option
The ASIO-Guard option in the VST Audio System page of the Device Setup dialog
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 audio channels that do not need to be
calculated in realtime. This leads to less drop-outs, the ability to process more tracks
or plug-ins, and the ability to use smaller buffer sizes.
To activate ASIO-Guard, proceed as follows:
1. Open the Devices menu, and select “Device Setup…”.
2. Open the VST Audio System page and activate the ASIO-Guard option.
This is only available if the Multi Processing option is activated, see “Multi
processing” on page 24.
Restrictions
Only the audio channels with their plug-ins as well as VST instruments support the
ASIO-Guard technology. To get an overview of the plug-ins that support it, open the
Devices menu and select “Plug-in Information” to open the Plug-in Information
window. To activate or deactivate the processing of a plug-in in the ASIO-Guard path,
check or uncheck it in the ASIO-Guard column.
The ASIO-Guard cannot be used for:
- Realtime-dependent signals
- VST instruments with more than on e MIDI source
- External effects and instruments
- Plug-ins that have a different bit version than the operating system
If you activate the monitoring for an input channel, the audio channel is
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.
