I have acquired an MT-32 and cannot get sound from it using the Sound Blaster CT3670 ISA.

The MT32 seems to be working as it plays the built-in demo tracks. It also works with the Atari ST (with both Cubase Lite and games) without any problems, however when connected to a PC it does not produce any sound.

I'm using a Gameport - MIDI cable, the interesting thing is that when connecting the mt32pi emulator with the same cable everything is fine (e.g. in Monkey Island), while the real MT32 doesn't produce sounds. I have tried removing and inserting the MBFEN jumper - no effect.

SOFTMPU correctly detects the MPU port and the DSP. I have no other problems in games using Sound Blaster audio.

My autoexec.bat file:

1SET SOUND=C:\DRIVERS\SB16

3SET MIDI=SYNTH:2 MAP:E MODE:2

Computer is 486SX, MS DOS 6.2 system.

I would appreciate any help.
