LFO's also output positive/negative signals. If you want to modulate the
gain of a VCA using an LFO or a VCO you need to reduce the signal and
add an offset voltage. While VCO's and VCF's generally provide panel
controls to do this (the main pitch or cutoff knob, and a modulation
intensity knob) most VCA's don't.
So to use such a VCA with an LFO or VCO for
tremolo/panning/ringmodulator effects you would need some kind of
control voltage processor such as http://www.buchla.com/200e/256e.html
(or a much simpler one)
