It seems that the 566 can be current controlled as well, and in this 
case the sweep range is more like 1 to 100, I have a schematic for a 
BBD phaser at hand where this is used. They hold the voltage input at
some fixed level, and inject the current at pin 6. Hm, sounds as if one 
could add a simple expo converter and have linear and exponential FM.
