[midi] -section, I would guess.

(Where are the docs for this thing? Dosbox.conf did not list that option. )

DOSBOX.CONF lists all options. Just create new one (you are probably using some old DOSBOX.CONF).

Well, I used the one that comes with Win32 installer (version 0.61). Havent changed other options than the number of ticks and added automounting of directories to the end. There is no "intelligent"-option.

Also, adding that option did not help. Still says "unable to access the MT32 on IRQ channel 2". Right now the midi-section of my dosbox.conf is as follows:

1[midi]
2# mpu401 -- Enable MPU-401 Emulation.
3# device -- Device that will receive the MIDI data from MPU-401.
4#           This can be default,alsa,oss,win32,coreaudio,none.
5# config -- Special configuration options for the device.
6
7intelligent=true
8mpu401=true
9device=default
10config=

I'll check into this and see what I can find.

you have to use dosbox from this thread (newer version):
Dosbox & windows driver problem

intelligent mode was not implemented in dosboxmt32 before.

Dang programmers not keeping their builds up to date. Oh.. never mind.

😊

...No. Or at least, I'm not sure. I downloaded the installer from dosbox.sourceforge.net, installed and then overwrote it with the one at Canadacows(?) homepage, that is dated March 27. This one seems to be newer.

(However, I did strings dosbox.exe and there is references to "intelligent"-option). I'll download this version as soon as I get out of work, which will be about 7 hours... 😀

"intelligent" option is in dosbox.conf. When you download new version, delete the old file and create new one by executing in dosbox:

config -writeconf dosbox.conf

Then edit the file and change "intelligent=false" to "intelligent=true".

YES! It works with this one. This is great.

Hello,

there is a general timing error in midi sync with my real MT-32 sound module.
While most games like sierra and lucas arts adventures work without problems, the legend classics spellcasting 101, 201, 301 and several others
produce timing errors.
The MT-32 soundmodule shows the message "Exc .Buffer overflow". This means, the SysEx and Midi data is transferred too fast.

Until now, did not find a way to fix the problem.

You have to slow down dosbox for the moment when sysex is loaded.

An easier way is to sell your MT-32 and buy one of these: LAPC-I, CM-32L, CM-64, CM-500 😉

Hallo Robertmo,

nice answer, but I prefer a technical solution implemented in dosbox.
Because a Roland MT-32 ist freely programmable, it should be possible
to compensate it's shortcomings compared to {LAPC-I, CM-32L, CM-64, CM-500}.
Timing problems are easy to handle, if you want to:
- Get some kind of FIFO buffer
- Feed buffered data with correct speed to sound module

bye

I guess that only a few people have real MT-32 to experience this problem, so I think it has very low priority...
Of course, I am sure that if you submit a patch, DOSBOX developers will be happy to include it.

Bit 6 of the status byte (one that program reads from status port - 331) is "data receive ready". This way, MPU-401 tells the program if it's ready to receive data (or command) from program. Because emulated mpu-401 handles all incoming data and commands immediately, this bit is always 0 giving green light to programs to send data.

This is the way to control speed, but I have no idea on how to know if real mpu-401 is "full" or not.
