SOUND TUTORIAL/2. Create a song

2-6.Creating song data for Saturn

Finally, combine all the data you have created so far and try playing the song on the target.
Please follow the steps below.

1) Start the sound simulator

Start the sound simulator.

2) Converting SMF files

Convert the created song data to data for Saturn.
First, select "Convert Standard MIDI File" from the "Function" menu.

Figure 2-36 Selecting "Convert SMF file"

Use the "Add", "Insert", and "Folder" buttons to add the SMF file created in "Section 2-4: Creating a song" to the list, and click the Execute button to convert.

Figure 2-37 Converting SMF file

Select all SMF files in the folder by selecting any file in the folder containing the file you want to select. ( *Multiple selections possible )

3) Creating sequence data

The converted file created in 2) is [Original file name]. It will be CNV.
Select "Create Sequence Bank" from the "Function" menu.

Figure 2-38 Selecting “Create sequence bank”

[Original file name], which is the converted data created in step 2) . Collect CNV files as sequence data.
At this time, the SONG numbers are numbered 0, 1, 2, etc. from the top.
This SONG number is important because it is specified when playing the song.

4) Creating a map

Select "New" to create a new file.

Figure 2-40 Creating a new map file

Up to 128 map information can be stored in one file.
When new, map 0 is displayed as an edit map.
Create information that summarizes tone data and song data.

Figure 2-41 Map edit window

In the edit window, double-click the list part where data is set.

A newly created map has only one piece of data, so add any missing data by selecting "New Data" from the "Edit" menu.
In this way, information that summarizes tone data and song data is created.

Perform data settings, etc. on the screen shown in Figure 2-42. To select the data type, click in the frame to the right of "Data Type" to open the pop-up menu shown in Figure 2-43, and select the desired data type.

5) Loading data

Select "Launch Map" to send data to the target.

Figure 2-44 Select “Launch Map”

At this time, if you have not started the sound system, select "Start Sound System" from the "File" menu to start the sound system.

At this point, check the following points in the Edit Map window.

Figure 2-45 Edit map window

6) Playing songs

Select "Sound Simulator" from the "Function" menu to display the sound simulator screen.

Figure 2-46 Selecting “Sound Simulator”

Figure 2-47 Sound simulator screen

If you are not satisfied with the sound, try modifying the data in each software and repeating the linking and simulation steps.

Notes on map data size

If the target is a "sound box", it has more memory for sound than the Saturn, so please be careful that the final data of the final map does not exceed 7FFFFH .

Note that SGL's sound-related functions allocate 78000H or more for PCM playback, so if you use SGL and also play PCM streams , make sure that the last data in the map does not exceed 77FFFH . .

7) Creating a binary file of the map

Select "Create map information text file" to create a map data file to be placed on the Saturn.

Figure 2-48 Select "Create map information text file"

All of the song data has now been created, but the data that will actually be loaded onto the Saturn requires at least the binary data of the tone file used in the map, the sequence data, the map binary file, and the sound driver file.
Additionally, if you are using DSP, you will also need a DSP program file.

Figure 2-49 Song data file to be passed to the programmer

sound driver map binary tone data sequence data DSP program file

Note: File names other than the sound driver are determined when the file is created.

In addition, if one map data is large enough to fit in the memory of the Sound CPU 68000 at a time, you can save the effort of the game program by creating a dump file that combines the tone data and sequence data in one map. can.
With the data loaded, select "Combine Send Files" from the "Function" menu to create a dump file.

Figure 2-50 Selecting "Combine sent files"

In addition to this file, the only files necessary for the game are the sound driver file and map file.

Note: File names other than the sound driver are determined when the file is created.

The only thing left to do is to actually incorporate it into the game and play the song, but for details on how to incorporate the sound data into the game program, please refer to ` `Chapter 2: Sound Data '' in ``Data Transfer''. please.
