		Beta drivers for Sound Blaster series cards
		      with Multi-instance Support
		      on OS/2 2.1 (MMPM2 ver 1.1)
				Nov. 3, 1993

The beta driver provided here support multi-instance: meaning that you
can open as many digital audio or MIDI players on the desktop as you
want, and play the music sequentially (note: only SB16 supports simul-
taneous WAVE and MIDI playback, see note below) as you switch focus from
one player to another. Just replace the corresponding driver with the
one that supplied here in c:\mmos2

For Sound Blaster: 		sbd2.sys
For Sound Blaster Pro(OPL2):	sbpd2.sys
For Sound Blaster Pro2(OPL3): 	sbp2d2.sys

			Procedures for installing SB16D2.SYS
		that has simutaneous WAVE and MIDI playback capability
				Nov. 3, 1993

The driver sb16d2.sys (and the supporting dll sb16.dll) supplied with
this zip file allows the simutaneous WAVE and MIDI playback, which means that 
you can open a WAVE player and a MIDI player and have them playing at the same 
time: not that you would likely want to hear Madonna and Michael Jackson singing
at the same time, but a lot of game programs actually plays MIDI music in the
background and WAVE format sound effect for action shots!

NOTE: IMPORTANT!!!
This feature is only supported on SB16 and NOT for other members of SB series!
This is because SB16 has a on-board programmable timer while the others don't,
and the timer resolution on OS/2 2.1 (32ms) is not good enough

Here is how to add this feature to your system:
1. Load the new sb16d2.sys driver.
2. copy sb16.dll to c:\mmos2\dll
3. Make sure the following lines, in c:\mmos2\mmpm2.ini, are the same as they
   appear here: 

  in [ibmampmixsb01] section:
  ...
  RESOURCEUNITS=2
  RESOURCECLASSES=2,1,1
  VALIDCOMBINATIONS=1,2,2,1
  PARMSTRING=TREBLE=50,BASS=50,PITCH=50,GAIN=70,BALANCE=50,VOL=100,INPUT=LINE,OUTPUT=SPEAKER,RESOURCEDLL=SB16,RCID=4
  ...
4. reboot the system.
