Is Kontakt a higher sound quality sampler
than Vsampler3?(i.e.,why exactly are you using Kontakt instead of Vsampler?)

I am also curious if you had a chance to
try out RT Player Pro yet. I read that it
has VoiceMachine listed as a compatible plugin. Unfortunately, you have to buy
their hand controller to use the program,
and it is a VST host only, No DXi.
