ASIO support
This driver release includes full ASIO 2.2 support. Just select “ASIO Echo PCI” from within your
ASIO-based application.
New features for Windows Vista
The scheduler in Windows Vista has a new feature called MMCSS, or Multi Media Class
Scheduler Service. MMCSS is intended to enable audio software to run at the highest priority to
avoid glitching.
The ASIO driver included with this release supports MMCSS. On the ASIO control panel, you will
see two new settings.
• Use Vista multimedia priority boost: Checking this box tells the ASIO driver to use
MMCSS to run at a higher priority.
• Lower Vista window manager priority: Checking this box causes Vista to prioritize audio
playback and recording over drawing windows on the screen.
Both settings are checked by default.
Finally, the ASIO driver now stores the ASIO control panel settings separately for each individual
user.
I don’t see all of my inputs and outputs.
This is probably due to the fact that another program is using them. The most likely culprit is the
Microsoft wavetable synthesizer, which is being opened by your audio application as a MIDI
output device. Make sure that your audio application does not have “Microsoft GS Wavetable SW
Synth” selected as a MIDI output device.
If your outputs still don’t show up, you may have some other software that’s doing the same
thing.e
