 +The SD-8516 is paired with the SD-450 sound subsystem; named for featuring 4 independent voices with 5 waveforms available, each with a programmable ADSR envelope. Let's dive in with an overview of the architecture and a quick look at INT 11h, the sound services library. If you are just interested in how to play sounds and music in your own games, you can skip ahead to [[#sound_and_music|Sound and Music.]]

 +== Sound and Music
 +It is possible to play sound sound and music in the background (or while-you-wait) on the SD-8516. The boot chime "GECF" is proof of this.
 +
 +There are two main ways you can play sound and music. One is by directly controlling the music registers. As listed above, you can write data to these registers and the "SD-450 Sound Chip" will play the sounds. This can be a good way to make sound effects. Alternately you can use the Music Player system in INT 11h. 
 +
 +Although INT 11h is used to make music, you can create short scripts to play sound effects. Each channel operates independently so you can have up to four simultaneous sounds playing at the same time. Making a sound effect relies entirely on your own creativity. Here's an example of the sound we use for the system beep; it's a good example of a directly programmed sound:

 +
 +play_beep:
 +    ; Play a beep (~880hz A4)

 +    LDAH $48     ; wait_ms -- wait for C ms (blocking)
 +    INT 0x11
 +</codify>
 +
 +As you can see -- nothing to it!
 +
 +=== Music Player System
 +First you will define a series of commands such as:
 +
 +<codify armasm>
 +BOOT_CHIME_DATA:
 +    ; Tick 1: setup + G/C
 +    .byte $01, $00                      ; tick index 1
 +    .byte $F1, $83, $00                 ; set tempo = 131ms
 +    .byte $F2, $03                      ; min_note = 3 (eighth)
 +    .byte $01, $28, $20                 ; v1 duty 12.5%
 +    .byte $01, $17, $2F, $05            ; v1 PWM + G4
 +    .byte $02, $17, $1C, $02            ; v2 tri + C3
 +    .byte $00
 +
 +    ; Tick 2: E/A
 +    .byte $02, $00
 +    .byte $01, $28, $80                 ; v1 duty 50%
 +    .byte $01, $17, $2C, $05            ; v1 PWM + E4
 +    .byte $02, $17, $14, $02            ; v2 tri + E2
 +    .byte $00
 +
 +    ; Tick 3: C/F
 +    .byte $03, $00
 +    .byte $01, $28, $40                 ; v1 duty 25%
 +    .byte $01, $17, $28, $05            ; v1 PWM + C4
 +    .byte $02, $17, $10, $02            ; v2 tri + C2
 +    .byte $00
 +
 +    ; Tick 4: F/G
 +    .byte $04, $00
 +    .byte $01, $28, $20                 ; v1 duty 12.5%
 +    .byte $01, $17, $2D, $05            ; v1 PWM + F4
 +    .byte $02, $17, $14, $02            ; v2 tri + E2
 +    .byte $00
 +
 +    ; Tick 5: silence
 +    .byte $05, $00
 +    .byte $01, $10                      ; v1 off
 +    .byte $02, $10                      ; v2 off
 +    .byte $00
 +    ; End
 +    .byte $00, $00
 +</codify>
 +
 +With this data, you can play it like this:
 +
 +<codify armasm>
 +    ; Initialize sound system
 +    LDAH $40
 +    INT 0x11
 +
 +    ; Point ELM at our song data and load it (AH=07h)
 +    LDELM @MUSIC_DATA
 +    LDAH $07
 +    INT 0x11
 +
 +    ; Start playback: set state and prime the clock
 +    LDAH $05
 +    INT 0x11
 +
 +    ; Blocking playback loop: poll until song finishes
 +player_loop:
 +    YIELD
 +    LDAH $00    ; Poll Music Player
 +    INT 0x11    ; This checks if there is a note, and plays it.
 +    LDAH $0F    ; Check player state
 +    INT 0x11
 +    CMP AL, 1   ; 1 = still playing (0 = song is finished)
 +    JZ @player_loop
 +
 +    ; Done
 +    LDAH $43    ; Stop player (turn off all channels)
 +    INT 0x11    ; This causes the music player to stop.
 +
 +</codify>
 +
 +Now, if you have a game loop, you can just put this code in your main loop:
 +
 +    LDAH $00    ; Poll Music Player
 +    INT 0x11    ; This checks if there is a note, and plays it.
 +
 +It will quickly check if there is a note and play it. In this way you can have "background music".
 +
 +=== DATA2 mode
 +If DATA2 is set to 1 on a voice channel (default is 0) then it will experience a momentary shutoff before the next note is played. If you cannot achieve the correct ADSR envelope to separate notes, you can enable this mode. It is especially useful for guitar strum-like sounds -- "chugging". Then again, I think the kids say 'djenting' these days. I read that somewhere.
