glissando intro

[Hans <hansfong@xxxxxxxxx>]

Hello list,

I'm working on a new piece and I need a some intro. I was thinking of 
doing something funky with a softsynth and a glissando. Think along the 
lines of the beginning of "Threshold" from the Steve Miller Band (or the 
opening of Jungle Love, also from Steve). I can't figure out how to do a 
glissando in Rosegarden, so does anyone of yous out there know that 
trick or some other way of making some weirdo sounds? Cheers,

Hans
