@redstudio, try moving Magma host card to different slot. Also check old ProTools installation guides for recommendations on using expansion chassis.

well, that it works in OSX does not mean much, i had that same situation with SATA cards and USB devices that things worked only in either OS.

the strange thing is that it chrashes for you, it would be more logical if one card just does not work.

i mean it does not show up, isn´t it, so how can it crash...

Yes, I have a fifth one mounted on a PC. What would be the suggestion? Replace one with another? The cards are all tested and working. 4 on OSX are perfect, I start with OS9 and the computer freezes. I don't even get the initial window. The gray video starts and it freezes with a screen like the previous photo before the little smiling Mac computer even appears... I remove any of the 4 cards and OS9 starts normally. Mystery

Thanks again Macintomh!

Wonder why Thomann even noted that erroneous 230 V requirement?

[Maybe I’ll order myself one for Christmas and give the whole tariff
situation some time to possibly settle down.] 

Thanks Macintomh.

Got a little bit excited… until I read the following caveat for US users:

“This item runs exclusively on an operating voltage of 230 V and therefore requires a voltage transformer to run in your country of United States.”

AND:

“Additional import duties may apply to this product due to U.S. Customs Regulations.”

hi aBc,
(don't worry, be happy)
"operating voltage 230 volts" (lol) is misleading as the micromix2 is powered by USB (5 volts) only - there is no other voltage supply - see the pics

ordered one, gave it a try - and it works :-)
(this is no vintage device, not  even "new old stock", say it is "new NEW stock")
so here we have an usb interface you can buy NEW today and it lets you record on OS9 g4mini i can confirm
greetings

hm. the UAD-1 is weak (compared to UAD-2 or powercore) and wont take much resources (in the sense of I/O), and the powercores beside it are only active after initialisation.

but what else could make the driver in OS9 see only 3 cards where it is definetely supposed to support 4? would be great you had a fifth to replace one.
