-===== Introduction =====+How do you know what value to feed the 16-bit SID frequency register to get a certain note? The easy way is to use ready made tables calculated by someone else. In this case, the only thing to keep in mind is that if you want a specific tuning, the tables you use will be different depending on the machine you use. For standard concert pitch (A4 440 Hz), use [[base:pal_frequency_table|this table]] for a PAL C64 and [[base:ntsc_frequency_table|this table]] for a NTSC C64.

Then you have to calculate yourself. but how?
