Much appreciated. I've taken the matter up with RME who, on first assessment, believe that it should work and think the issue might be with JRiver. [Not sure how this could be the case given that other devices are able to support simultaneous input / output via ASIO]. How, out of interest, do you switch between standard JRiver playback as the input and ASIO Line In as the input? [I'm trying to figure out a method that is simple enough for family use.]
yes ist must be a JRiver issue and how JRiver uses the driver.
Note: Soundforge 7.0 uses the driver correct
Soundforge 11.0 does not use the driver correctly!!
Proposal for JRiver:
Open Live in ASIO-mode:
it should be possible to select each input which the soundcard provides separately (just a list with clickbox of all the inputs).
The user must than make sure he is not using twice the same input, i.e. assigning the same input to different software.
The implementation of the offset channels thing is restricting and error prone.
The RME Fireface can simultaniously work as input and output even for various software.
So my conlcusion is that RME Fireface UFX and the driver are working correctly in multiclient mode if the software does it right.
at the same time I can:
-Play JRiver files from HD Zone: player)
-Play Spotify (made new Zone: JRiver audio input): here I assigned default playback device in Win7 to JRiver21
The open live in this Zone: WASAPI
-record from Fireface UFX (channel3,4) phono with Soundforge 7.0. However using Soundforge 11.0, it does not work as Soundforge 11.0 blocks the Fireface entirely. This I name back to the future....
-Record with cooleditPro2.1 (channel1,2) from cassette recorder
Note: Samplerate must be on single only!! The different software cannot play record at the same time in different sampling rates with RME Fireface UFX
