Same as in first picture on Orph2 LT homepage.

could it be a simple connection issue? try to wiggle the jack around
is the midi cable a known working one?
also remember that the midi jack should go to the MIDI-IN port of your midi device

Could we get another batch of the Morpheus II cards?

I have seen the message on the contact form as well but for now there are no plans to make more Orpheus 2 cards, all effort and time goes to the Xtreme card atm

I am wondering if there is any way to change the sterio channels via the driver.
I looked into Ophinit as well as Unisound and couldnt find any.
Why would I want to do that? Well, I just wanted to play Dungeon Master 2, and apparently that game has swapped stereo channels (I can confirm that in other games they are correct).
Did I miss anything there? Or isn't there a way to swap it and I would need to use a hardware solution (or for recordings - fix it on the recording device)

there is no option to do this via any driver available - crystal or 3rd party
I assume the game does not have a swap stereo option? the easiest way is to just swap the recording channels on post-processing

Alright, thank you!
There is no option in the game. But I will use a program called "Pedalboard" then to just swap them before recording.
Btw: I also checked to determine whether it's Orpheus Specific.
A friend tested with his ESS card (with Pro settings) and it's also swapped.

Also I do have a SB16 and another friend tested a SB AWE64 for me, and they are both broken in the game. As the game (which was released 1995!!!) does not properly support them (Sound not working on SB16 setting, and sounds bad and mono only on SB Pro setting).
So...the Sound processing of that game is a total mess. It's advertising spectacular directional Sound on the box. But... SB1 doesnt support it, on SB Pro it's swapped, and on SB 16 (released 1992) and everything newer it's completely broken. ^^

Can somebody help me understand the IRQs, DMAs, and environment variables?

Here is the summary from my orphinit configuration:

1* Ctrl (Crystal) - 538
2* WSS - 534 / IRQ 5 / DMA 1
3* SB - 220 / IRQ 5 / DMA 1
4* OPL3 - 388
5* Gameport - 200

ORPHINIT sets the environment variable ULTRA16 to 534,1,5,0.

What is the purpose of this? It seems to relate to GUS Max SB emulation. If I understand correctly, it’s telling GUS software that uses SB emulation to use the Orpheus 2 CS4237 chip in WSS mode? However, if I want to use WSS then why wouldn’t I just select WSS in the game options (if available) ?

ULTRASND.BAT sets the ULTRASND variable to 240,7,7,7,7.

If I understand correctly, this tells it to use 240h, IRQ 7, and DMA 7. Is this correct?

Therefore, to enable all features of the Orpheus 2, I need IRQ 5 (WSS/SB), IRQ 7 (GUS), DMA 1 (WSS/SB), and DMA 7 (GUS) ? (two IRQs and two DMAs)

EDIT: It looks like I also need IRQ 2 (or 9?) available for MPU-401 intelligent mode. (I can’t disable 2 on my motherboard so I think I need 9?)

You're correct that you need an IRQ/DMA for each of the SB/WSS and GUS PnP options. And an IRQ if you want to use the MPU-401 interface with games that require an interrupt.

The Orpheus II is basically three sound cards in one which is why it needs so many hardware resources.

Thanks very much. Do I understand the IRQ/DMA usage correctly as well?

Yes. Assuming those hardware resources are available, you should be able to assign them.

Depending on the system you are using with the Orpheus II, you might need to reserve them in BIOS.

This actually has nothing to do with Sound Blaster emulation of any kind. It is used by some DOS software to determine the appropriate resources for a native-mode WSS-compatible CODEC, so that it can be used to provide up to 16-bit, 48 kHz stereo playback. This is usually for cards that lack the configuration interface of the original Microsoft-branded WSS board, and was originally introduced for the UltraSound MAX and 16-bit playback daughterboard of the original UltraSound (hence the name ULTRA16).

For instance, configuring Cubic Player to use the GUS 16-bit daughterboard will allow high-quality playback on Orpheus (all versions), using this environment variable to find the hardware. Similarly, Impulse Tracker will do the same when using my modified driver for any WSS-compatible hardware for which the resources are specified by the ULTRA16 environment variable.

It is interesting that some WSS-compatible CODECs can provide playback at up to 64 kHz sample rates. The CS4237B does not, but most designs based on the InterWave will do this via their CODEC module (but at a non-standard I/O port), as well as some designs based on the CS4231.
