Hello!
I have a ThinkPad 380Z with a Crystal 4237B audio chipset running Windows 98SE.
I am trying to enable the use of the MS Wavetable Synth to play DOS games using GM.
I have installed the WDM drivers for my chipset and everything works well, including playing MIDI files in Windows but also the SB + Adlib emulation under DOS.
Under Control Panel->Multimedia->MIDI, the Microsoft GS Wavetable SW Synth is selected as a single instrument.
Looking under Device Manager, I see three devices:
- Crystal WDM Audio Codec
- Crystal WDM Audio Control Registers
- Crystal WDM MPU-401 Compatible
The only device with an address in the usual MIDI range is the MPU-401, using 330-333 and IRQ 9.
So here is my question.... When launching DOS games under Windows, should I hear sound when I set a General MIDI device at 330?
I can't hear anything, Duke3D's setup even says it can't locate a MPU-401 adapter at 330....
Of course, SB or Adlib emulation works.
Is there something I am missing?
