200e

"the resolutions were chosen to try and match the sensitivity of the human nervous system to 
various parameters. For example, humans are very sensitive to pitch, so a higher resolution 
DAC might be used to drive an output that was intended to control pitch, e.g. 225e Note 
buss."

I think you are incorrect on this one.  The quote reads, "Their characteristics are selected to 
enable accurate representation of underlying perceptual parameters."   Perhaps it means that 
the DAC and ADC resolutions are chosen based on the needs a user has, of representing any 
conceived sound.  So basically, if I want to make a sound that resembles a dorsal fin coming 
into contact with a human face, the Buchla 200e has the ability to represent that accurately.  
So basically, they are my perceptual parameters.
