I've been wondering about this: the hypertriangle controls a phaser 
which means the notch/pole frequencies, right? Is this frequency 
control linear or exponential and if it's linear is this not just an 
argument for having an expo converter in front of them to make the 
sweep constant speed in musical intervals rather than frequency?

You mean a (compressed) sine? :-)
