Every Voxengo is a jewel.
They’re incredibly stable, good sounding, well crafted, useful and relatively inexpensive.
I sincerely recommend you to buy “Patchwork” from Blue Cat to use, do channel routing, and set-up different plugin racks and configurations, ready to load at a mouse click.
I use all them every day with JRiver without ANY issues.
Patchwork even lets you load VST2 and VST3 inside it without problems and already comes with some basic but very useful eq, compression and channel utilities.
Concerning -free- voxengo’s ... I use Marvel EQ and can recommend it without any doubt.
Multichannel, multi-configuration and linear phase.
Of paid ones, I’m using GlissEQ and Elephant2 limiter at the end of the chain with -1dB of ceiling margin, just to be sure it would catch any sporadic peak that could clip the output.
