This program is intended to replace the control panel applet provide with the M-Audio Quattro USB 4 input USB audio interface. The control panel supplied by M-Audio does not work on Windows Vista although the drivers do.

This program will allow you to:

• Change the ASIO operating mode of the Quattro to select the bit depth, sampling rate and In/Out configuration when using the Quattro on Windows Vista 32bit.
• Select the ASIO latency when using the Quattro on Windows Vista 32bit.

The program works by locating the Quattro driver's ASIO settings in the registry, reading the current settings and allowing you to select and save new settings.

The settings that have to be changed are located in a registry location that requires administrative privileges to save changes so if you have User Account Control (UAC) enabled (the default Vista setting) you will see a UAC security prompt both during installation and each time you run the program.

You will likely need to disconnect and then reconnect the USB cable from the Quattro to have the settings change take effect.

Driver Installation: This program requires the M-Audio provided drivers to be installed. In some cases a generic Microsoft provided driver will end up installed. Check the driver installation page for information on how to verify and update your drivers.

Note: This is the first release of this program, it works on the systems I have used for testing, but let me know if you have any problems with it. (email address below)
