I threw together this little patch to be used as an abstraction like so: [inrange 36 48] to monitor pitches that are within the range 36 to 48. When the pitch falls within the range, [inrange 36 48] reports 1, as soon as the pitch leaves the range, it reports 0. I may have overlooked the existence of an object that does this, but anyway, maybe it's insightful for you to see a way to do it with basic objects. Instantiate one for each pitch-range you want to monitor. gr, Tim
