At the risk of drawing out another "Death to Doepfer" war...

I think Doepfer makes what you're looking for.  It's clearly a software
based quantizer where you select the scale (semitone, major, minor, etc).  I
think it's a good model to design from.  I've implemented a similar
simplified quantizer using a PIC where you can select semitone or octave
steps.  

If you do it in software, you can make the tuning scales table driven and
use some sort of switch (sw or hw) to select the table.
