Dave Smith Instruments SYNTHESIZERS

Well, the Amp section has an extra control called VCA Level that 
basically allows you to move the zero point (silence) of the 
amplifier up. If you crank it all the way up it essentially overrides 
the Envelope section and produces sound at full volume constantly (a 
drone).

It was a more common feature on older synths...the SCI Pro-One comes 
to mind. Les'see...who designed that? I can't remember... ;)
It made it easier tweak with both hands - just flip the Drone switch 
and you don't have to keep hitting the keys to make sound.
