How to check the sound box


Basic operation check method for Saturn sound tools


  1. First, turn on the target machine (Saturn Sound Box) and Macintosh. After turning on the power, the BOOT ROM inside the sound box starts and initializes the chip. When this initialization (usually takes 1 or 2 seconds) is successfully completed, the LEDs on the back will blink in a continuous flow from LED1 to LED8.
    At this time, when you check the SCSI connection using software such as SCSI Probe on the Macintosh, "SATURN DEVELOP-BOARD 1.00" is recognized in SCSI number 6.

    All Sega Saturn sound tools use SCSI communication to control the sound box, so the SCSI connection is important. Connect the cable to the Macintosh as quickly as possible, and use a highly reliable cable.

    *If there is a problem with the above conditions, there may be a hardware problem with the sound box or Macintosh.


  1. Next, start the sound tool SndSimulator from Macintosh. At this time, SndSimulator automatically transfers the sound driver to the target device (sound box) via SCSI. The same thing can be done by selecting "Transfer Sound Driver" from the File menu. The sound driver is a file named "SDDRV.TSK" located in the same folder as SndSimulator, and is the program code for the SoundBox CPU, 68000 (transfer address starts from 01000h). Also, "SYSTBL.TSK" is a system table referenced by the sound driver, and is transferred at the same time as the sound driver (transfer address starts from 0400h). Combining these two and omitting unnecessary processing for the sound driver for the actual Sega Saturn machine (such as controlling the rear LEDs) is "SDDRVS.TSK", which is the programming box (MODEL-S) or the sound driver for the actual machine. This is a driver (transfer address starts from 0h). This "SDDRVS.TSK" is basically not used for producing sound data, but by performing "Transfer S-Box sound driver" from the function menu and transferring "SDDRVS.TSK", you can You can simulate the sound produced by the exact same sound driver.
    After starting SndSimulator, try "Start Sound System" from the File menu. The transferred sound driver will now start working. If the sound driver is working properly, LED1 and LED3 on the back will blink (if a MIDI keyboard etc. is connected to the sound box, LED7 or LED8 will also light up due to MIDI active sensing). (It may flash).

    * If there is a problem with the above conditions, the SCSI communication between the Sound Box and Macintosh may not be working properly.


  1. Try opening the sample sound map. If you open the sound map for the first time, you should receive an error message saying "file not found" when transferring, but this is not a problem.
    SndSimulator searches for and transfers the data (data file) to be transferred based on the path (what file name in which folder on which disk). If this path is not set correctly, a "File not found" error will occur. In this case, please refer to the SndSimulator manual and set the path correctly.
    After setting the path, select "Save" from the file menu, and data will be transferred using the new path from now on. If you move or delete the transfer data file registered in the sound map in the Macintosh Finder, please reconfigure the path in the same way.
    The LED on the back will stop blinking during SCSI communication, but will start blinking again once communication is completed normally. If the LED remains lit, the SCSI communication or sound driver may have hung up, so please reset the sound box and retransfer the sound driver.
    Next, select "Sound Simulator" from the function menu, click on sequence 0 to highlight it black, and press the start button. A sample song should now play.

    * If there is a problem with the above conditions, the appropriate file may not have been copied to the Macintosh HD, or there may be a problem with the connection between the sound box and the playback device such as an amplifier or speaker.
