Dear Don,

	You can produce produce portamento with the 'divide-
	by-N' system. The Junos did it very nicely and more
	recently the Basstation and Pulse mono synths. Its just
	a matter of allowing small enough 'centile' increments between
	each note so that the transition during the portamento
	sweep does not produce noticable steps.

	Regards
