Hey Matt and Mac,

Thank you very much for repplying !

Excuse me but I'm a newbie concerning Music computering and I have some difficulties to understand drivers system

My BB version is 2012.5 and I work under Windows 7 64 (I7 processor, 12 gb ram) with the Roland VS700 set (soundcard and console). So,yes, it deals with ASIO drivers.

In Sonar, in Preferences, in Driver mode, I checked "Share the Drivers with other program"
In BB, in Options, Preferences, Audio, I set "ASIO Always On" (but the first time I used BB, I remember it was on MME drivers and with "ASIO Always On" unchecked, and it didn't work with Sonar (?); I will try again.


Thank you again for your help
