Its a clone of the Gallant SC6000. Also Terratec Maestro 16 is equal.
IMHO a very good Signal-To-Noise Ratio. Also non-PnP.
Drivers I use available @ http://terratec.ultron.info/Audio/Maestro/16/Driver/

01.12.2019 13:27 269389 M16CS_Drv_OS2_1.04.exe
in particular since it uses the CS4248-KL
Unzip M16CS_Drv_3x_Disk1.exe. Then Extract mix-set.exe from gal6n.lzh to your drivers directory.
Unzip M16CS_Drv_9x_1.20.zip. Then Extract to your drivers directory.
run gsetup.exe inside Driver Directory. A Line is added to config sys. Don't move it, it has to be loaded before HIMEM.SYS
in autoexec.bat add
SET BLASTER=A220 I7 D1 T4 (or whatever you configured via jumpers and gsetup)
C:\DRIVERS\MIX-SET.EXE /M:15 /WAV:15 /FM:12 /CD:12 /MIC:0 /LINE:0 /ADCS:LINE /Q
Also. If you use an external Midi Module like MT-32 or SC-55 add http://bjt42.github.io/softmpu/ since I had several system hangs without it.
add to autoexec as well
LH C:\DRIVERS\SOFTMPU.EXE /SB:220 /IRQ:7 /MPU:330 /RA50
You can install SB Pro Drivers in Windows 3.11
In Windows 95 too. Or use the Drivers in the Drivers Directory from M16CS_Drv_9x_1.20.zip. Either way manually add MPU-401 and Gameport as well since it will not be recognized by the OS because it is not PnP.
