I totally agree with most other comments: Volume Logic is great. It actually does something good to your music instead of ruin it. After two years I'm still VERY MUCH hoping for an official rebirth. Unlike other plugins, Volume Logic is basically a 5 band compressor/limiter with auto gain control and an adjustable bass boost algorithm. For those that have paid for it two years ago and have gotten it to work on Leopard (like me after some serious Google effort), I'd recommend the 'Pop' preset with 75% drive and 25% bass boost. Although VL can not be fully manually tweaked (attack/release controls are missing), the ample amount of presets more than make up for that imho. There is no plugin that comes anywhere near the quality that VL delivers. Please, bring Volume Logic back to life!! I would easily shell out twice the money it cost originally.

After upgrading to Snow Leopard, Volume Logic itself seems to be fully functional. However, there are errors in the console log that have something to do with 'iTea' VL apparently uses. I'm not a developer, but just looking at the console messages (search for iTea), it looks like a serious incompatibility to me.

I also noticed some visual artifacts on Volume Logic's level meters, but they don't seem to impair functionality though.
