Introduction
Welcome to ASIO4ALL v2! This manual enables you to make the most of your ASIO4ALL installation, especially as it comes to the advanced features newly introduced in this Version of ASIO4ALL. The ASIO4ALL v2installer should have added two new icons to your desktop, one being a link to this documentation and another to launch the ASIO4ALL control panel in off-line mode.

Getting Started Setting up your audio software
In order to make use of ASIO4ALL, you need to configure your audio software accordingly. How you would do this depends on your particular application. Generally, you would always enterthe audio configuration menu and select ASIO -> ASIO4ALL v2. There now should be a button to launch the ASIO control panel. How this button is labeled depends on your particular software. Once you press this button, the ASIO4ALL control panel should appear. Please consult the manual of your audio software for further assistance, if necessary! Sometimes, the audio software indeed would not providean ASIO control panel option. This is the case with e.g. Winamp and Foobar 2000, for which ASIO output plugins exist. For configuring ASIO4ALL with these applications anyway, you can launch the off-line control panel from the desktop. Note that the off-line control panel launcher works like a mini-ASIO-host of its own and does not reflect the current device status of any instance of ASIO4ALL thatmay be open at the same time! Changes made in the off-line control panel will have an effect only after you restart the audio application. Settings made in the off-line control panel, however, will have no effect at all for applications that have been configured with the ASIO4ALL (on-line) control panel launched from inside the audio options dialog of the application. Once you made it into theASIO4ALL control panel, you can now proceed with some basic configuration.
