I've got a Mac Book Pro lap top that has a 2.2 Ghz Intel Core 2 Duo processor and 4 GB of RAM, while I'm running Pro Tools with a Digi 002R audio interface. Maserati VX1 Vocal Enhancer plug-in in Pro Tools LE 8. I haven't had a need to look at the manual, so I can't say anything about it's make up. It also has three different contour modes to choose from, and a further series of parameters with delay. The VX1 Vocal Enhancer consists of knobs for sensitivity, bass and treble, compression, and output level. It also does share a lot of the same sorts of parameters as the other plug-ins, so if you've used one or two of these Maserati plug-ins, you should feel comfortable across the board. The plug-in shares a similar looking interface to the other plug-ins in this collection, which is pretty easy on the eyes and easy to use overall. I installed the plug-in along with the full bundle of Waves plug-ins, so there wasn't anything specific about getting this one up and running.
This one in particular is designed as a one stop shop for vocal processing.
Maserati Collection of plug-ins, designed by Waves and famed producer/engineer Tony Maserati. Maserati VX1 Vocal Enhancer is a plug-in that is a part of the Waves Ltd.
