Sound Engine Commands
80 - AF: Sets the note duration using the tick count table at $8586. The sound engine does not have the concept of tempo, all time control must be done through ticks. The following length values are actually used: 80 90 A0 00 01 02 03 04 05 06 07 08 09 0A 0C 0E 0F 10 12 14 15 18 1B 1C 1E 20 24 28 2A 30 36 38 3C 40 48 50 54 60 6C 70 80 90 C0 FF E0 xx: Uses the volume envelope selected from the table at $85B1. Each volume envelope is defined by length-value pairs; the last item has a length of FF. 23 volume envelopes are defined. E2 xx: Sets the duty cycle of the pulse tracks. 00 / 40 / 80 / C0 corresponds to 12.5% / 25% / 50% / 75% respectively. E3 xx: Reduces the output volume of the track by (xx + 1). E4 xx: (used in sound effects only, controls the pulse hardware sweep unit) E5 xx: Detune, operates by adding xx, unsigned, to the period register. Higher value means more downward detune; there is no way to detune upwards. E8 xxxx: Unconditionally moves the track pointer to xxxx. Used for looping a song or sharing entire streams between tracks. E9 xxxx: Invokes the pattern at xxxx. Patterns can be nested once within other patterns. EA: Returns from a pattern. EB xx: Starts a local loop that plays the contents xx times. Like patterns, they can be nested once. EC: Ends a local loop. ED: Enables vibrato. EF: Disables vibrato. F8: (used in sound effects only). This enables the DPCM channel F9: (used in sound effects only, seems to silence the DPCM channel) FA xx yy zz: Plays a DPCM sample by writing xx, yy, zz to $4010, $4012, and $4013 respectively; does not interrupt currently playing samples. Unless you are planning to add your own samples, the only parameters that appear in the game are 0F F0 10 for kick, and 0F F4 20 for snare. FB xx yy zz: As above, but will interrupt playing samples. FE xx: Causes the track to fade out by reducing the final volume by 1 per xx ticks. FF: Ends the current track. Channel data: 00: pulse1 (sfx) 01: pulse2 (sfx) 02: Triangle (music) 03: noise (sfx) 04: pulse1 (music) 05: pulse2 (music) 06: DPCM (music) 07: Noise (music)
Sound effect structure
The sound effect data has two parts: a segment for pointers and a part for the music data. Both are terminates with
. For example: the menu sound effect starts with
04 88 55. The first byte has to do with the sound channel (this needs more research), however, the last two bytes translates to a pointer in Little Endian. Here's how to compute the pointer:
The pointer points to
FF. The game's sound engine uses this pointer in particular to disable sound channels. The menu sound effect is one example of this. If you disable sound channels with this method, they won't enable back.
