Here's a new music tool which needed to be written before the importer:

Mario 64 Sequence Inserter v0.1.

Don't be fooled by the name, it currently only replaces existing sequences with custom ones, but I'm sure eventually it will also handle insertion so you can have more than the original 34 sequences.

The imported sequences are placed in the ROM after the original sequences (which are left untouched for a future "cleaning" tool), and the pointers are adjusted automatically. You can use sequences bigger than the original ones you're replacing, as there's plenty of empty space in the ROM for this.

Usage is:

insert_seq sequence rom_file sequence_number (check insert_seq.txt for more details).

There are two sample sequences, smb3.m64 and rescue_egg.m64. The first one is the SMB3 Overworld 2 and the second one was imported from Super Mario World using the current working build of the importer tool. Don't except the importer output to be this good, this was an exception.

Useful hint: if you specify number 666 (ie, insert_rip smb3.m64 mario64.z64 666), ALL the sequences will be replaced with the one you're inserting. This is very useful so you can hear which instrument set fits your sequence better.

I so need to learn hexdecimal.

So are you saying, messian, that you can possibly add more tracks to the game than replacing the ones that are already in?

I also think I have a theory on how the pirahna music works. There could be an action code where when you go near the pirahna plant that activates a fade activation on the music. There could be one code on the Pirahna that makes the music change when aproched. Maybe if you can add the same code to a different object, it will set off.
Can anybody search this?

There is an object that has similar effect. The "Camera Anchor?" object.

The Camera Anchor has been already discussed in the last page of this thread.

There's no need to learn hexadecimal to use the Inserter tool as well as the importer (whenever it's released). However, you'll probably have to correct stuff in the .mml file (which is text-based, so you can edit it in Notepad), especially if you are importing from a MIDI file using some MIDI->MML tool.

I might as well produce a simple editor for the sequences produced by the importer, so you can change instrument/volume/pan/gate time of each channel until you find good settings without having to use a hex editor.

Although I may not have an explanation to the lullaby music in hex, I think I have the general idea.

When you wake up the pirahna, it will not play the music. This could link to the behavior code that turns it on and off.
If that code can be found, it could possibly be put to other objects with some simple editing.
I might as well search it out when I have the time.

Here's a Sequence Repository with files that can be used with the Sequence inserter. All of them except smb3.m64 were produced by the importer. The songs aren't looped as the importer doesn't do that yet.

Here's a few of these sequences inserted in the game!

Wait. Does the importer add m64 files, or create them?

The importer creates the .m64 files from .mml files (which, in turn, can be produced from MIDIs using one of the available MIDI->MML tools). The inserter saves the custom sequences into the ROM. There's no hex editing involved, but just like SMW you'll need to do some minor changes to the .mml file if you want a good result.

This tutorial from SMW Central is a good guide for the MML format.

I got the loops to work correctly, so I am pretty close to a first release. Perhaps as a Christmas gift

?

I haven't gotten use to the tools yet, except the one with making your own music.

So the first release will be like, everything put together?
If so, that will be nice!

How ironic. The first MIDI file I converted (Using a program that doesn't have all the translation errors titled MID2MLL) was the 12 days of Christmas!

I'm using tinymm, as it seems to be the most usual choice. Did you got mid2mml from SMW Central? I think I may have tried it, but it was in japanese and the output was a bit strange.

Along with the importer, there will be a simple program called fix_mml which can correct the .mml files produced by tinymm (the octave raisers/lowerers are inverted) so they are (almost) ready for import.

So, the steps to custom music will be (assuming you are working from a MIDI file):

1 - Convert MIDI to .mml using tinymm (or another program)
2 - If tinymm is used, run the file through mml_fix
3 - Manually edit the .mml sequence (it's a text file) to include tempo, volume and other settings.
4 - Run the importer to produce a .m64 file
5 - Use insert_seq to save the sequence into the ROM

1. There is a translated verison of the program available too
2. I looked at the tutorial, and there are a few things that make me unsure, like adding instruments
3. Maybe you can combine tinymm and mml fix to get rid of a few steps.
4. Can you make a tutorial video on this after you release the program?

I tried the translated version, but still instead of regular characters I get just "garbage". I guess it's something related to language settings/unicode or something along that lines.

I like your suggestion #3 ("maybe you can combine tinymm and mml fix to get rid of a few steps."). I'll see if I can make mml_fix do all the adjustments needed so that the file is ready to be processed by the importer. Another useful possibility is to make music in Channel 10 (in MIDI, reserved for drums/percussion) be treated as a drum track - in Mario 64 you do this by setting the instrument to 0x7F.

I'm not sure if I'll do a video tutorial, I'm thinking more about writing some guides/documentation on my site.

First of all, thanks messiaen for investigating so much time in this topic and especially for keeping up Linux portability

I'm thinking about creating a frontend* for the various tools using QT (a platform independant library for creating GUI programs). Messiaen, I hope you don't have any objections against that. Also, to keep up Linux support, would it be okay to you if you released the sourcecode for the sequence bank ripper (and any other tool which I may have overlooked but which could be useful still)?

* well.. would be nothing too special though, really just a GUI for not having to use the CLI

EDIT: okay, scratch that. Just saw you already embed the Sequence Bank Ripper into the parser.

I am creating a simple Windows frontend - I swear that's the last time I'll touch the WinAPI - for the sequece inserter, which IMO is the only program that really needs because it requires more command-line arguments. For the other tools, you can just "drag-and-drop" (in Windows) the input files.

But if you want to create a sort of an universal frontend, including the sequence ripper and all the extra tools, that would be nice.

The only source that I won't include in the first release is the importer code, because it's an incridible mess. Although most original ROM/SMW functions from Addmusic were removed, there are still bits of useless SPC-related code and header files I haven't cleared up.

But don't worry, after the experimental first version is tested out a second, much cleaner release will also include the source so other people can improve and optimize the convertion.

For documentation purposes, here is how the 'instrument set' table works. With this missing part solved, it's possible to change which instrument set each sequence uses and probably add new sequences in the game, probably up to 127 sequences.

The table is located at 0x7cc620 and it's loaded separately from the music sequences:



0x007CC620   0046 0052 0054 0056 0058 005A 005C 005E

0x007CC630   0060 0062 0064 0067 0069 006B 006D 006F

0x007CC640   0071 0073 0075 0077 0079 007B 007D 007F

0x007CC650   0081 0083 0085 0087 0089 008B 008D 008F

0x007CC660   0091 0093 0095 0B0A 0908 0706 0504 0302

0x007CC670   0100 0122 0111 0122 010E 0113 010F 0112

0x007CC680   010B 010D 0221 1001 1401 1501 1601 1701

0x007CC690   1801 1201 1901 1F01 2101 1A01 0E01 1B01

0x007CC6A0   1A01 1C01 1D01 2501 1401 2001 1E01 1B01

0x007CC6B0   1A01 2301 2401 1B00 0000 0000 0000 0000

The green bytes consist of 0x23 halfwords (2 bytes), which is the same number of sequences in the ROM. Each entry is actually a relative pointer to the 'instrument set' used by that sequence. To read the table, just use the sequence number * 2 (halfword) + 0x7cc620 (start of the table).



For instance --> Title Screen Music (sequence 0x02)

               = 0x0054 (value in the table for 0x02 at offset 0x7cc624) 

               + 0x7cc620 (start of the table)

               ----------

               value at 0x7cc674 = 0x0111

Now 0x01 and 0x11 are actually two separate bytes, not an halfword. I'm not sure if the first one is also an instrument set, but the second one certainly is. So, this sequence uses instrument set 0x11 (in decimal = 17).

This number relates to the "NInst" instruments in the .ctl file. Using srip (download from dextrose.com), you can extract all (or most) sounds in the ROM and it outputs a control.h file which includes information about the sound structs used in the game in a sort of reconstructed .ctl file.

There are 37 NInst entries (0x25). Each one of these contries contain an index to the individual instrument sounds.
SRIP outputs all sounds in the format A00 + Ninst number (00 to 37) + sound index.

Here is NInstrument NInst17 (0x11), the Title Screen SMB Music instrument set:

Sound1700, 0x00 = Snare Drum
Sound1701, 0x01 = Fingered Bass
NULL, 0x02 = NULL = same as last one (0x01)
Sound1703, 0x03 = Organ
Sound1704, 0x04 = Steel Drum
Sound1705, 0x05 = Trumpet
Sound1706, 0x06 = Slap Bass
Sound1707, 0x07 = Synth
Sound1708, 0x08 = Clavinet
NULL, 0x09 = NULL = same as last one (0x08)
Sound1710, 0x0A = Drum Sample (hi-hat)
Sound1711, 0x0B = Drum Sample
Sound1712, 0x0C = Drum Sample
Sound1713, 0x0D = Drum Sample

This is the index used inside the Title Screen Music (for the 0xC1 instrument command, or '@' in mml2m64). Some of the NInst are sound effects, such as explosions and Mario sounds.

If someone could help labelling out all the sound files (trying to keep names close to standard General Midi instruments), that would be of great help.

Getting back to the table, here is the code that copy this pointer table to RAM, in case we want to move it in the future:

803198BC: LUI V1, 0x8022
803198C0: ADDIU V1, V1, 0x6B58
803198C4: LUI A0, 0x007D
803198C8: SW V0, 0x0000 (V1)
803198CC: ADDIU A0, A0, 0xC620 ; 0x7cc620
803198D0: OR A1, V0, R0
803198D4: JAL 0x80318040 ; BlockDmaCopy
803198D8: ADDIU A2, R0, 0x0100

0x80226b58 is a pointer to the location of this 'instrument set' table in RAM. (It will point to 0x801D0370, or wherever it gets allocated).

This is the data from the instrument table (see previous post):



Sequence #00. Pointer = 0046  NInst = 11 and 10   (probably used for Mario Sounds)

Sequence #01. Pointer = 0052  NInst = 01 and 34

Sequence #02. Pointer = 0054  NInst = 01 and 17

Sequence #03. Pointer = 0056  NInst = 01 and 34

Sequence #04. Pointer = 0058  NInst = 01 and 14

Sequence #05. Pointer = 005a  NInst = 01 and 19

Sequence #06. Pointer = 005c  NInst = 01 and 15

Sequence #07. Pointer = 005e  NInst = 01 and 18

Sequence #08. Pointer = 0060  NInst = 01 and 11

Sequence #09. Pointer = 0062  NInst = 01 and 13

Sequence #0a. Pointer = 0064  NInst = 02 and 33

Sequence #0b. Pointer = 0067  NInst = 01 and 20

Sequence #0c. Pointer = 0069  NInst = 01 and 21

Sequence #0d. Pointer = 006b  NInst = 01 and 22

Sequence #0e. Pointer = 006d  NInst = 01 and 23

Sequence #0f. Pointer = 006f  NInst = 01 and 24

Sequence #10. Pointer = 0071  NInst = 01 and 18

Sequence #11. Pointer = 0073  NInst = 01 and 25

Sequence #12. Pointer = 0075  NInst = 01 and 31

Sequence #13. Pointer = 0077  NInst = 01 and 33

Sequence #14. Pointer = 0079  NInst = 01 and 26

Sequence #15. Pointer = 007b  NInst = 01 and 14

Sequence #16. Pointer = 007d  NInst = 01 and 27

Sequence #17. Pointer = 007f  NInst = 01 and 26

Sequence #18. Pointer = 0081  NInst = 01 and 28

Sequence #19. Pointer = 0083  NInst = 01 and 29

Sequence #1a. Pointer = 0085  NInst = 01 and 37

Sequence #1b. Pointer = 0087  NInst = 01 and 20

Sequence #1c. Pointer = 0089  NInst = 01 and 32

Sequence #1d. Pointer = 008b  NInst = 01 and 30

Sequence #1e. Pointer = 008d  NInst = 01 and 27

Sequence #1f. Pointer = 008f  NInst = 01 and 26

Sequence #20. Pointer = 0091  NInst = 01 and 35

Sequence #21. Pointer = 0093  NInst = 01 and 36

Sequence #22. Pointer = 0095  NInst = 01 and 27

The next step is to map out the instruments/samples, so we can have a guide to be used in custom music (I really could use some help on that. Here is a model:

NInstrument NInst 15
Used in: Lethal Lava Land (sequence #6)

00: Simple percussion loop
01: Voice 'Uhs'
02: Sitar drone notes
03: Sitar melody

or

NInstrument NInst14
Used in: Inside Castle (sequence #6)
Sound1400, 0x00 = Strings
Sound1401, 0x01 = ?
Sound1402, 0x02 = ?
Sound1403, 0x03 = Pizzicatto string
Sound1404, 0x04 = Cello? (or low and deep woodwind?)
Sound1405, 0x05 = Eletric Piano
Sound1406, 0x06 = ?

SRip somestimes doesn't produce all the Soundxxxx files in a NInst. I'm almost sure it's because it is a repated sample, already used before.

Hi, i dont know if this is a bit off topic.
I got the Super Mario 64 sound bank as wav files and i want to make a soundfont out of it but i have no idea how to do it, can someone help me?

Sorry for my bad english, i am from Denmark and i am only 11.
