Welcome to the Orpheus Sound Card homepage.
Currently this page serves as a quick setup guide , it will eventually be updated and become fully functional.
Orpheus is a PC ISA 16bit soundcard , aimed for DOS usage.
Please keep in mind that this is still and ISA soundcard based
around a 1997 audio controller working inside systems up to 30
years old and playing DOS games that
have low bitrate and compressed samples to accomodate the hardware limitations of the time.
More info and development log can be found HERE
||PCMIDI Resources Control (only installed when
PCMIDI is onboard)
P - jumper closed = port 330 , open = port 300
3,5,7,2 = select *one* IRQ for use
defaults shown: port 330 and IRQ2 selected
|| MIDI Signals Control to allow a dual-mpu
If PCMIDI is installed and you also activate CS4237 MPU device you can select which MPU device controls each port. Move jumper to I (for PCMIDI) or CS (for CS4237) for each jumper
WTC= Wavetable Connector
JYC = Joystick Connector
MOC = MIDI Out Connector
defaults shown: all ports controlled by PCMIDI MPU , if there is no PCMIDI installed on board the jumper block has no use
PCMIDI MPU interface info:

This is a driver software developed specifically for the Orpheus Sound Card by VOGONS user 640K!enough
It is INI driven like the official Crystal driver , so you have to edit said INI file to change resource and mixer settings.
Usage is pretty straight forward: edit ORPHEUS.INI if needed and lauch ORPHEUS.BAT , that's it!
You can have multiple INI files and use them with the /F: switch , for example: ORPHINIT /F:DMA0.INI
Grab the latest version HERE.
For more information and bug reports please visit the offficial VOGONS release thread HERE.
a. for an Orpheus soundcard with PCMIDI installed add these lines to AUTOEXEC.BAT (assuming UNISOUND is located in C:\UNISOUND directory)
SET BLASTER=A220 I7 D1 T4
C:\UNISOUND\UNISOUND.COM /VC80 /VL80 /VF60
with these settings SoundBlaster is configured at port 220 , IRQ 7 , DMA 1
b. for an Orpheus soundcard with CS4237 MPU add these
lines to AUTOEXEC.BAT
SET BLASTER=A220 I7 D1 H3 P330 T4
C:\UNISOUND\UNISOUND.COM /XOM1 /VC80 /VL80 /VF60
with these settings SoundBlaster is configured at port 220 , IRQ 7 , DMA 1 , HIGH DMA 3 and CS4237 MPU is using port 330
Official Crystal DOS drivers:
Important notice: these drivers are completely unoptimized for Orpheus, they are
only useful in case something does not work with current DOS init programs so
you can at least use the card in some problematic scenario.
Specific Orpheus support , coding and testing based on feedback are still undergoing.
HERE you can download a copy of the official Crystal DOS drivers.
There is an ORPHEUS.TXT with installation info inside the archive - basically all you have to
do is extract the files to a directory, edit CWDAUDIO.INI in case you want to use different
resources and chose if you want to have the CS4237 MPU device enabled or disabled.
Then add the lines described in ORPHEUS.TXT in your config/autoexec and reboot!
Those drivers DO NOT offer a way to activate s/pdif output under DOS.
Although Orpheus is designed as a DOS sound card windows drivers do exist - but sadly due to it's closed-source nature some limitations are in effect...
EEPROM restore/config tool:
Use FLASH.COM to restore the card's eeprom settings and disable or enable CSMPU device at ports 300 or 330.
Duke Nukem II : CS4237 chip does not support all ADPCM sample compression modes the game uses. Please use
AdLib sound effects for the game.
Tyrian and Tyrian 2000 : On most systems the game only works with WSS and DMA0 selected. You can easily change
resources on the fly by modifying the BLASTER variable and running UniSound to re-init the card or use ORPHINIT with an
INI file that specifies DMA0 to be used. This just seems to be the game's sound driver incompatibility with the CS4237.
How to order it:
There are 3 flavors of the card - prices listed include registered
