I'm a R&B , Rap producer and I found these demos to be amazing, no other plug- ins are touching them, these are next on my buy list.
and be sure to download the tempo delay, it's free, and it kicked the ass of many plugs like nomad and many others, although voxengo dosen't always hit, like the free tube, these people got thier ears tuned right and thier programming smoothed to a steady flow, keep programming.
Even buying some "professional stereo delay plug-in", I still use this amazing plug-in.
As soon as you try Voxengo TempoDelay it becomes an essential component of your gear, because it's really reliable, higly configurable and it reacts EXACTLY as you expect.
I would pay a lot of money for this VST, thanks Voxengo!!!
