According to:

http://messe.harmony.../New-PCI-E.html

the HDSPe series will be available at the end of March (now). The time is very close...

The previous version of the driver was tested only with the PCI-e cards and not the PCI ones. No wonder it sounds terrible...

PS. I Tried swapping IOPCIFamily.kext myself too, same results...

Some of you mentioned flashing the firmware. Does the new firmware tie the card to OSX and make it unusable for other OS'es? Is there any 'danger'?- except for the flashing go pear-shaped and brick the card...

no, there is no real danger if you are using Windows, it will work even with older (MME) drivers. But if you use linux, I can't recommend using new firmware, because there are still no Alsa drivers with new HDSP series functions and channel layout...

Good you mentioned it. Cheers mate! I'm on Mandriva so I better hold off experimenting then...

According to the thread above:

The new RME HDSPe series cards (for the PCI-Express bus) perform 64 bit Core-Audio calculations in hardware. This functionality is missing from the PCI version and thus there is incompatibility between the HDSPe driver and the HDSP PCI series. The result is noise in the output stage.

I know this isn't a real solution, but IF your motherboard has on-board SPDIF out, you can route that to the Multiface SPDIF input and select it as an output for the software you're using. The OSX 16c drivers work and you can set the card to lock to incoming SPDIF.

Totalmix in OSX controls the Multiface just fine (including MIDI control) but as the tinkerers here know, anything you try to route in or out of the PCI card sounds like it's going through a Big Muff (which of course could be your style :P ) On my system, the latency is not fantastic, but it's very playable (feels like 12-15 ms). And I'm still getting the benefits of the Multiface routing and DA conversion.

My motherboard doesn't have a SPDIF in, otherwise I'd try routing the Multiface SPDIF out to the motherboard SPDIF input. That should work as well.

As for "doing our own"... good luck with that. Without knowing as much as RME does about how their low-level code works... but you never know :unsure:

Hi Limini,

That's excactly what I am doing these days.

But I've also made an order for a MOTU Traveler. The MOTU 828 mkII FW, which I've already tested works smoothly, I believe the same will happen with the Traveler.

I find no reason why RME would release Macintel Drivers for HDSP when they are not usable...

... especially considering their PCIe card isn't in distrubution yet. Maybe there's something we're not getting... :P

Hard to say, but I hope within the next two months.

From the RME Newsgroup. This sounds like good news but I am still skeptical about it.

Any news on this? I tried this yesterday with the lastest drivers and got distorted sound as most others have.

FYI, the HDSP PCIe card has obviously been released a few days ago. (Hidden) announcement:
http://rme-audio.de/...opic.php?id=322

proof:
http://www.thomann.d...e_hdsp_pcie.htm

Strangely enough they haven't announced anything on their home page so far. Also, the Intel Mac driver in their downloads section now mentions to be compatible with the PCIe card only, whereas the old website listed the PCI card as well when they released the driver (actually 3 months before the PCIe card became available). Weird.

However, I'm seriously thinking about selling my FF400 which I'm using now as a substitute and get a PCIe card for my good old multiface.

that's what the RME peoples say:

the new RME HDSP PCIe Cards support the Apple CoreAudio floating point format in hardware. that's why they moved off from the driver the related routines for converting to this format. this results in a distorted sound.

Not any more! :censored2:

Yes, they patched out the floating-point conversion code when they ported the PPC driver to MacIntel.
So I just fuking patched it straight back in again :-)
I've got 7 years and $5000 of RME gear and this is the first issue I've ever had with them, but I'm not laying
out another $1000 for 3 PCIe cards if they are going to play stupid {censored} with their customers.


P.S. Please comment on your experience with this - especially in multichannel setups. I can optimize the conversion routines for SSE3 'n' stuff to tweak the performance etc. This release is just familiarizing myself with hacking Mach-O wrappers :-)

Here's a patch for the HDSP MADI cards too :-)

I don't have one of these cards, so I patched it "blind", as it were


Best of luck with it, lemme know how you get on!


Edit: sorry removed this one 'coz it doesn't work. I'll work on it!

0xdeadbeef: really great work!
I have checked the 0.11 patch for the HDSP Madi and AES32.
Hardware Rev. 205 for Madi and latest driver 2.54.
Everything works!
I like your patched version even better than the real thing :(
I would say, you make a nice patcher for all rme pci devices
ans then we can close this thread.
