Bass rider works Great in Sonar, Vocal rider does HALF of what it should. It will ride the Vocal in relation to the target you set, it just can't compensate for the music getting louder. I still do Less automating by using it, but not getting to set it and forget it (or set it and tweak it) SUCKS. (still saving time, but annoying that the Host we've invested our $ with is leaving us only partially compatible and not 'ready' for the future (which is now btw). I just downloaded Cubase 6.5 and might give Studio One a try as well. It's bad enough waiting around for fixes that don't ever come and now to have to wait for compatibility to happen or not happen.
