I’ve tested out Varis on a myriad of different sources and have yet to run into an Achilles’ heel for it. Everything from live jazz instruments to MIDI-programmed hip-hop drums and samples sounds marvelous through Varis. I particularly enjoy what it does on the mix bus. I’m amazed at how well it handles material from the low and low-mids and also how it affects the higher frequencies. Not all Vari-Mu compressors are created equal, and if you’re looking for proof, look no further than Varis by HCL. Stellar plugin!
