I don't own the Nomad Factory BT GEQ-12 plug-in myself, and I've only used it within Pro Tools HD systems at the studio that I work at. We have a number of different studios on site, so there are a few different systems that we're running this plug-in on. The A room has Pro Tools HD running in tandem with a Mac Pro computer with 10 GB of RAM and dual 2.66 Ghz Intel Xeon processors. We've got Apogee converters and a Neve 8068 console as well, so everything we hear is of the highest quality. We never really have issues running plug-ins or really with any performance issues at all, and this one doesn't tax the system in the least...
The Nomad Factory BT GEQ-12 is a pretty useful plug-in, but admittedly it's not my first choice for equalization of any kind. Most of this has to do with the fact that I'll usually use parametric equalizers unless it's a specific situation where I think a graphic EQ will work better for whatever reason. As far as graphic EQ plug-ins go, this one is definitely a nice one as it's got a nice and warm tone and offers a good amount of flexibility between the 12 bands and the band width feature. I like how easy this is to use, but if I'm looking for any sort of preciseness, this isn't going to be the place I look, but again this is primarily just the nature of the plug-in. I do think that it could be a bit cheaper as an individual plug-in, but if you get this in a Nomad bundle, it's definitely one worth checking out.
