i am trying to set up my hardware synth (Kurzweil K25) as an External Instrument in Cubase. The problem i’m facing is that although i set up 2 stereo return buses one of them comes in as mono. This is not a problem of my audio interface, i can see that both stereo pairs from the synth are coming in as stereo and i have set up the correct routing for the returns in Cubase.
I’ve tried this numerous times starting from scratch, with different channels, settings, creating the midi device from scratch, using a preset midi device, restarting … etc
am completely stuck, have searched the manuals and read all relevant docs … could this be a bug ?
