the cpu load that a plugin uses is variable and fluctuates alot depending on the max polyphony + number of simultaneous voices played and the effects on the instrument (heh, i.e. plugins on top of plugins).
i can have like, 15 vanguards on my 1.6ghz p4 if i set em all to monophonic bass patches with no effects on them.
or i can add 1 vanguard with 32 poly and strike a massive 13th chord with delay, reverb, EQ + compression on it and it'll slay my CPU
