Hi Ken,

There are some double phrases in the note frequency example paragraph.

I'm surprised it uses an LFSR but at the same time had a bot of an a-ha moment. They could have used the LFSR too for the program counter, if 15 lines of music was enough. What's your theory about why this isn't used more often in other (computer) chips with linearly stepped ROMs (that don't need random-access)?
