i'm sure if you email the developer he'll sort things out - i've had a fun exchange of emails about the products and the two knob solution is working out fine. it really pulls out vocals and whereas I've had to use eq before as well as compression, the two knob vocal king seems to do a better job on its own.

i also got a free version of the lexicon reverb plugin (it came free with some hardware I bought) and the 'medium vocal plate' preset is simply gorgeous
