Christian Knufinke Software has released public beta versions of SIR2 for both Windows VST (v2.beta3.123) and Mac OS X VST/AU (v2.beta3.124).

The Windows version now includes 32-bit and 64-bit (x64) builds. To run the 64-bit version of SIR2 Windows Vista 64 AND a 64-bit host application is required. If you are running a 32-bit host software on a 64-bit operating system, you have to use the 32-bit version. The new installer includes a 32-bit and a 64-bit binary of SIR2.

This is a service for all regular purchasers of SIR2, and those who want to get a picture of the current 64bit support. The beta has the normal demo restrictions until a SIR2 license is purchased.

Also new in these beta versions:

• Triangle envelope functionality.
• Finer Pre-delay adjustment.
• Search functionality, if impulse file not found.
• Ability to store EQ-presets (right mouse-click into EQ-Envelope).
• Improved project-portability between different workstations (relative filename will be stored too, so if the default impulse-response location is different, the IR will be found). Please note: to use this function, the project has once to be saved with this new version.
• New look.
• Support for "Ctrl+mouse click", for one-button mouse Macs.
