that means there is an irq/dma conflict , you should go to device manager and see what is allocated for the crystal devices

I'm currently in the process of asign manually IRQ/DMA for the card.

Managed to fix the loop on the sound by giving the CS CODEC IRQ 5 and DMA 1 and 3
To make the OPL work I changed the interval to 0388-038B.

Now I'm onto the GUS.

I forgot to mention that I have a x16GS daughterboard connected and 16mb ram in the Orpheus II. As far as I know that shouldn't be a problem if I have GUS working ok, right?

good, great to have some progress
X16GS is irrelevant to the GUS portion - no worries there

GUS installed without problems, it reset the config I had for the OPL, so I changed it back.

I installed PCMIDI and it works fine, the only thing is that the device itself (the Roland MT-32) doesn't serve a purpose I can't phisically edit the volumes or sounds. I turned the volume all the way down to 0 and still sounded at full volume. Gonna test it with my SC-55MkII to see if the same happens.

The other problem is that OPL sometimes reverts back, but I can live with that.

not sure if this is what you mean but PCMIDI is just an interface - a bridge between the system and the synth connected to it
any volume change is made either by midi data or the synth itself with it's volume controls

opl should not change address once you manually set it up - is there some montherboard soundchip that is not disabled in bios?

I get that PCMIDI is just the interface, but the weirdest thing is happening, I choose Roland MPU as MIDI device, open a test file and the Roland lights up the green light (Midi message), the music starts to sound and then I thought, what if I turn the MT-32 off (hitting the power button in the back), surprise music continued...

I don't really know what could it be, but maybe is the interwave that's producing sound and not the MT-32??

This is not possible, if you turn the mt32 off then no sound is produced. On the multimedia settings what device have you selected for midi out ?

MIDI out is selected: Roland MPU-401

I recorded a video where you can see how the MT-32 "reacts" as is playing the notes of the test MIDI file, but then I turn it off and the music keeps on playing.

I did some more testing and I managed to get it working. I need to "mute" the Synth output in volume control, only then the midi will be controlled by the MT-32, if not, somehow I think the wavetable DB steps on it and sounds on top of the MT-32.

Maybe there's another way of turning the wavetable DB off, but I haven't found it yet.

There's a video of how to properly play with the MT-32:

Sorry for the bad quality, but I did it on the go with the cellphone

I am currently on mobile so I cannot watch the videos but the best solution to this midi problems is to assign the wt header to crystal mpu at port 300 and mt32 as-is at pcmidi/port330
This will ensure you don't get both devices playing at the same time

By assigning the WT header you mean change the jumper J2 to 2-3 and choose port 300 for Crystal MPU??

Yep, you will be running a dual mpu setup

Gonna try that, I don't need to install the multiport driver, right? just choose what MPU I'll be using for WT or the external output

No multiport driver needed, just the stock crystal/Roland ones you already have

Changed the jumper, now I can't get Crystal FM, OPL and WT to work... tried to change the ports but keep getting BSOD... I guess I'll leave it as is and just mute the synth output

Is this happening in other motherboards as well?

Haven' t tried yet, I had the card on a MMX system with DOS only and it worked OK, this is the first time trying to use it under Windows.

Finally I managed to install it and make it work, with the WT header under Crystal. Now everything sounds, however, WT synth now sounds really noisy like static in the background... That's probably the Crystal MPU to blame though.

no this makes no sense, MPU just sends digital instructions to a synth/wt board, nothing to do with the analog side of things that can produce static and noise
it seems that something is going wrong with your system as it's whole behavior is very problematic

That could be it, I'm just at a testing stage and haven't isolated all the cables and such I'm using. However I did notice a small change by playing "Ultrasound Synth" (WT) when connected to the Crystal MPU, it sounded at a lower volume and with a lot of noise in the back, when playing from the PCMIDI it didn't have that kind of noise. But both are coming out from the same line output so...

ultrasound synth has no connection to pcmidi or csmpu - you are hearing sound generated entirely inside the interwave chip via it's own interface
but on the mixer side of things it is connected at the same point as "synth/fm/wt"
I really think something is going wrong on this p3 system you are using

It may be, but I tested it back with PCMIDI and synth via Windows it sounded louder and without noise, back to the Crystal Jumpers and it sounds at a lower volume and with a lot of background noise...

Now I'm off to testing another set of speakers 🤣.

Anyways, thank you so much for your help I really love the Orpheus II and I'm glad I can use it in another system until I revive my MMX 🙁
