Hi Folks,

I have a sound card that using the Opti MAD16 chipset (I borrowed it from
a friend to try out under FreeBSD; I don't have the manufacturer name).

This card can be setup by its DOS software to run in SB compatibility
and in Windows Sound System (WSS) mode.

Under FreeBSD-current, I'm able to get the basic SB and WSS modes recognized.
I.e I can get the kernel to recognize `sb0' or `wss0'.  

However, in neither mode am I able to get MIDI to work properly.  
Running `playmidi' results in a kernel error message: 

	``Soundcard: Sequencer not initialized''.

I can't seem to get `sbmidi0' to be recognized in SB compatibility mode.

This seems to come from "isa/sound/sequencer.c", since the `num_midis' 
variable is not being incremented during initialization of snd0.  Not 
surprising since `wss0' is implemented in `ad1848.c' which has no MIDI
support.

Has anyone been able to get external MIDI to work properly with the MAD16
chipset?

Thanks,
Koshy
