Good tip for scaling the controls...never even thought about that!
Wish I could do that with all my instruments and effects. For example, I like to automate ValhallaRoom's decay time, but its range is so great that the envelope often must change by only a couple screen pixels, requiring that the node values be typed in. If only SONAR allowed you to scale automation envelopes! But I've been begging for that since 2005 and it's not gonna happen.
