That's all fine, of course.  But if you follow that approach why would you 
use the discrete Schmitt trigger when an op amp version (1) works better, 
(2) is simpler and (3) is less expensive?

As far as accurate and stable tuning, I guess it's a personal matter.  I 
have ruined recordings by not retuning enough and I really appreciate a 
rock stable accurate module.  Others may not.
