PAL NES Square/Triangle Wave Note Values By Celius



This is a document that holds all values of every note on every octave that the -PAL- NES can produce for the Square and Triangle Wave. The lowest octave is listed as "Octave 1".

These will be listed as 11 bit values that can be stored into the sound registers. All values are rounded to the nearest number.


Note that for the Triangle Wave, these values will make a pitch one octave below that of the Square Wave.

Final note: Tables are meant to be displayed in Terminal font.


F = Frequency
