The Orpheus 2 LT is an upgraded OrpheusI souncard and as such the main features are the same:

• based on the Crystal CS4237B controller which offers SB/SB-PRO/WSS compatibility
• discrete YMF289B OPL3 chip
• 44.100hz 16bit S/PDIF output of all internal and external audio sources
• 4-layer PCB design with attention to analog output part and usage of audio-grade capacitors
• 2 MPU-401 options: internal CS-4237 UART interface or PCMIDI intelligent mode MPU
• Gameport, Line IN, Line OUT, MIC and Coax S/PDIF ports
• Wavetable daughterboard and AC'97 headers
• dedicated midi-OUT port with the ability to also use at the same time a common gameport->midi or DB15MIDI adapter for an extra OUT and IN ports
  
  So what is new over the OrpheusI design?
• revamped PCB design and analog output section which result in better sound quality than the original OrpheusI
• new way for OPL3 interfacing which allows the YAMAHA OPL3 to be accessible under Windows , no more CystalFM-only limitation under win9x
  
  Basically due to the experience gained from OrpheusI and better understanding of the CS-4237 audio controller a better soundcard was possible to make!
  

More info and development log can be found on VOGONS forum, in the OrpheusII thread.
Please also check the OrpheusI homepage for more info as both cards use the same CS-4237 audio controller.



29-JAN-2023 OrpheusII (LT) Windows9x drivers released, download HERE .



Driver is based on the last Crystal CS4237 driver version PV2860.
Just extract archive to a directory and when asked about CS4237B drivers point Windows to said directory.

Black OrpheusII LT boards need a firmware update which has been mailed to the few owners of these boards.

Remember that the onboard PCMIDI MPU-401 interface is not a PnP device and needs to be added manually
to the system if you are not making a fresh install from scratch. PCMIDI related files/drivers are located HERE .
