Hi, another newbie question here.

I have an RME soundcard at my disposal with 6 analog channels (it also has other types but I cant use those)
like this:

When I try to set up 3 output devices like this

I get the error message
separate audio device choice not supported; using sequential devices.

So my mixer ends up looking like this:

Which I guess corresponds to the "sequential devices'. Ofcourse I want AN 1/2 , 3/4 and 5/6. (7/8 is actually just headphones, but just to show how its acting weird)

I CAN however select Speakers (RME Fireface UCX) together with Analog (3+4) and (5+6) and then I get this

which is already a step in the right direction, but I really need all 6 channels.

I googled the error message and came upon this thread from 2003 http://lists.puredata.info/pipermail/pd-list/2003-10/014460.html but that just confused me more. I tried using these commands in the PD console but it's just giving me invalid command name errors.

I'm trying to achieve something along these lines (extremely simplified example)

I tried using ASIO but I can't select multiple devices like on the screenshots above and on top of that the audio it outputs is completely distorted. Very odd. (using MMIO now)

Any help is much appreciated.

@alex_d Hllo Alex,
If that is windows that you are using then you should use asio4all...... it's free..... http://tippach.business.t-online.de/asio4all/
It works very well (in fact better than some dedicated drivers).... You just select asio4all in Pd and the number of channels etc., If you select a "too" large number of channels then the extra channels will just be ignored (dropped).
Then in asio4all you select your multiple soundcards, and activate the channels that you want to use. The order in Pd will be the order in Asio4All.........
You will still need to get all of your settings correct (samplerate, delay, etc.) and it is a good idea to tick the "callback" box in Pd.
Come back to this thread if you have trouble setting it up...... good luck!
(PS....... use batch files to set the audio settings for your patch once you are happy.... that way you can set up testing scenarios without the audio hardware present, and return easily to a "normal" Pd with just your built in soundcard working)

Ahhh, I didn't notice that I could select Asio4All from the devicelist after selecting 'ASIO (via portaudio)'. I also had to up the samplerate to 2048 and it got rid of the distortion.

It works perfectly now, thanks a lot!!
