..so I was very happy when watching the youtube video "What's New In PreSonus Studio One 3.5" from the "Studio One Expert" channel , learning that it is now possible to choose different Audio Interfaces for Output and Input processing ("Playback Device / Recording Device" under Audio Setup) . But when I opened the Audio Setup page of Studio One I wondered why I do not see this -long awaited- option. I see more ore less the same Audio Setup Page as with 3.3 (see snapshot)

I am using two WC syncronized MARIAN PCIe Audio Cards: D4 and AD2 (System is 12 core and Win 7/ 64 BIt, current service pack and updates, works perfect with all of my DAWs)

I run a seperate AD Converter which is PC/ DAW- connected with my 8 Channel AES/ EBU PCIe-card "Marian D4" .

For digital and analogue monitoring I use a Marian AD2 PCIe-card (because of its excellent 32 Bit DAC) .

Again: when opening the Audio-Interface Setup I cannot choose "Recording device" and "PLayback device" seperately. There is not even the option so called. I can choose the MArian D4 or the AD2 Card.

by the way: The cards and drivers are fine, both working perfect under S1 and with all my other DAWs- OHH, I just recognized that I also cannot choose multi core support anymore ??? wow, whats that ?

I did a full de-installation and installed again. All the same. Totally strange, no multi core and no option to choose different input out devices. On my Mac everything works fine -- aargh , but I need the Win 7 System its my workhorse

I feel in a dead end situation. need some help or clarification what might be wrong with my system
thanks in advance
