Is it okay to use Controll Change 31 for both the start and end of a MIDI loop?

Q)

I have a question about MIDI loops. Is it okay to use Controll Change 31 for both the start and end of the loop?

A)

Yes, that's right.

What is the standard for MIDI resolution?

Q)

I have a question about MIDI resolution. Will it be converted as one quarter note = 480 steps?

A)

The time base is not changed at the time of conversion. The timebase supported by Sega Saturn is between 24-960.
In reality, the timebase is determined by the SMF output specifications of your sequencer.

How should I arrange the commands added to the beginning of the song?

Q)

Is there any problem with the method of arranging the commands added to the beginning of the song, such as bank program change, in the minimum step after conversion?
Or is it okay to put them all in the same step?

A)

Use the method of arranging in order with the minimum steps.
When arranged together, at the time of conversion

"The position of the program change at the beginning of the track is too late."

Returns an error such as.
The basic data layout at the beginning of each track is described below.

-------------------------------------------------- -------------------------------------------------- --------------------
1/1/000 (bar / beat / clock)
Tempo event (usually automatically inserted by the sequencer), bank change (# 32) 
1/1/001 (bar / beat / clock)
Program change, control change (MAIN VOLUME # 7, loop command # 31 at the time of loop, etc.)
1/1/002 (bar / beat / clock)
Note on 
-------------------------------------------------- -------------------------------------------------- --------------------

remarks

The number of clocks per beat depends on the resolution of each sequencer.
Also, set the MAIN VOLUME of Control change # 7 at the beginning of each track.
Depending on the sequencer, if multiple event data are placed in the same measure / beat / clock, the order in which they are displayed on the screen of the sequencer and the order in which they are written to Standard MIDI File may change.
If you want to clarify the order of the events, shift the data by one clock.

Since the processing of the Sega Saturn sound driver is based on 2 msec, even if sequence data that handles one beat as 480 clocks is created, when converted playback is performed, one beat has a resolution equivalent to 250 (when the tempo is 120). It will be played as if it was quantized.

Upper limit of total memory

Q)

There is a symptom that the file is corrupted when the total memory exceeds 0x80000. Why is this?
Is it because it is linked with the upper limit of sound memory?

A)

Is it the file on the hard disk that gets corrupted?
If so, this is an unreported example.
If data exceeding 0x80000 is registered in the map on the sound simulator, the sound memory of the actual Sega Saturn is 512K bytes, so it will not sound normally.
In particular, if the target is a sound box, it has 1 Mbyte of memory, which is 512 Kbytes more than the actual device, so transfer itself is possible, but the driver does not support it, so be careful.

AudioMedia2 is not available on PowerMac7200

Q)

AudioMedia2, which is an extension hardware, cannot be used with the PowerMac7200.

A)

"Audio Media 2" only supports "NU-BUS".
Therefore, there is no choice but to use "Audio Media 3" on the "PCI-BUS" Mac, but "Sound Designer II" does not support this, so please use software such as "Pro-Tools".

What's in the tone library?

Q)

Is there any tone library other than InVision's CyberSound?

A)

SEGA has no other tone library for licensees other than InVision.
Please note that various notation obligations will be incurred when using InVision's tone library.
