SID and Music Programming
This is where you find programming examples as well as hardware information about the SID, the soundchip inside the C64. This section also contain information related to music programming on the c64, such as music file formats and other things like that.
Playing readymade tunes
This section exemplifies how to play a tune in your own demos/games. The tune itself is done elsewhere, in a editor like JCH/DMC/SDI etc, or coded directly in assembler.

SID model detection
Is it a 6581 (the old one) or a 8580 (the new one) SID in your machine?
- detecting sid type - from “mathematica” by Reflex (This is the old and not 100% reliable method)
- detecting sid type - safe method - by SounDemon, based on a tip from Dag Lem. (Won't work in VICE.)
Frequency tables/calculation
- PAL frequency table - A4 = 440 Hz tuning table for PAL C64s.
- NTSC frequency table - A4 = 440 Hz tuning table for NTSC C64s.
Envelope manipulation
