Why not the piano as a reference for bass

The attack on a pipe organ on a really deep note takes time for the pipe/chamber to fill so the note comes on more gradually.

A synthesizer can play basically any waveform all the way down to subharmonic.  A subharmonic square wave with an instantaneous rise time is harder on the speakers that have to make the transition more quickly. 

I privately messaged Bill Stevenson, respecting his opinion on the latest Clavinova. 
All I can say is please let me know when you get to see a Clavinova at any one of the best concert halls in the world?? I will confidently say NOT IN MY LIFETIME!! Also, remember that yes, a synth can be programmed aimed to make subsonic frequencies, but what transducers can accurately reproduce them?? A 32 foot organ pipe will, even if you don’t hear the 16hz, your body will definitely feel it!! 
Wonderful discussion, but with many misunderstandings about the actual physics of the lowest frequencies. 

I cannot thank enough the person here ( i dont remember who) who recommended to use this small organ  interpretation of the Bach Klavier which is truly astounding :

   It is a collection of various Japanese musicians, essentially a small orchestra.

Only reference I could find is someone named K. Hata.

Thanks i will try to get it...
