Orm's implementation of the random phase might also be cheaper than your two fexpr~ for that part.

it's just "expr~" not "fexpr~" ;)
 
You might not have to be conservative with CPU
usage in your case at all however.

nope, and I need to be more intuitive (as this is a didactic material) and I consider this to be "simpler" - subjective 
 
It does work and might save cpu compared to fexpr~.

biquad~ is surely cheaper than fexpr~ !!! 
 
In my case I am trying a textbook implementation for now.

yep, that's what I was going for in that example, what you think? If you have more remarks other than efficiency, I'd like to know. 

cheers
