As of two most recent builds JSonar correctly reports peak meters when playing or recording within the project of Cakewalk Sonar. Simply use Control+Alt+M to read the peak meters for a current track or bus.

Please note that this feature has been implemented as a work-around as the up-to-date Control Surface SDK from Cakewalk does not provide an easy means of extracting this information from the host.

Please head over to the Development Builds section of this web site to download the latest development version of JSonar.
