Refer to the following topic viewtopic.php?f=57&t=38238
You can also go the website and refer to the documentation: http://bjt42.github.io/softmpu/

However, I'm not sure whether you can actually use this feature with an MT-32, due to the 5-pin MIDI DIN interface.

You can, certainly, but it requires the use of a go-between to perform the 38400-baud serial -> 31250-baud MIDI conversion. All serial-connectable MIDI modules perform this conversion internally, and any such model with a MIDI OUT port can be used to facilitate playback from a connected MT-32, including members of Roland's Sound Canvas family, Yamaha's TG and MU tone generators, and several Korg units. Presumably, something like the port-powered Midiman Portman PC/S could also be used, for an even simpler setup.

Here's a video in which I demonstrate MT-32 playback using SoftMPU's serial output functionality, albeit, through outrageously complex means:

Thanks Cloudschatze , then to use the SoftMPU is just a matter of having the Yamaha TG100 - Module only ? or i need to have connected the Yamaha TG100 - Modulo Midi and the MT32? Thanks in advance

DE-9 serial (COM1/2) -> TG100 TO HOST (PC-2 setting)
TG100 MIDI OUT -> MT-32 MIDI IN

Hosa manufacturers a fairly inexpensive 8-pin mini-DIN to DE-9 cable:
http://hosatech.com/product/dbk-100/

Compared to some of the later modules, the TG100 is pretty basic when used as a serial MIDI interface. Lacking routing options, the serial data arriving at its TO HOST port is simultaneously sent to both the internal tone generator and retransmitted through the MIDI OUT. This just means that you'll want to turn down the volume on the TG100 (or leave it's audio outputs unplugged, or send SysEx to disable RX channel reception for each of the 16 parts, etc.) when desiring only MT-32 playback.
