Tuning (SID)

[eptheca]

I would like to try out different tuning on my MIDIbox synths.

 

I found the sid_frq_table.inc, but I don't understand how the values have been calculated.

Could someone please help me with a formula or description on how to use the frequencies I want to have to calculate HEX values for the SID V2

 

Best regards

Halvor

It's described in the SID datasheet: http://www.waitingforfriday.com/index.php/Commodore_SID_6581_Datasheet#Appendix_A_-_Equal-Tempered_Musical_Scale_Values
