connected Kemper with Babyface Pro via analog, but I can't hear anything...

  • I hooked up my Kemper with Babyface Pro using main our L/R into BFP's analog in 1/2 (XLRs).
    I also did monitor out and direct out to BFP's In 3 & 4.
    Looking at TotalMix, the signals from 4 different sources seem to be well received because I see green bars on my BFP's 4 analog inputs in 'Hardware Inputs'.
    But I can't hear any sound.
    Actually there is no movement in 'Software Playback' and 'Hardware Outputs'.
    What am I missing here? What should I do to monitor sound from my Kemper via speakers (main out) connected to my Babyface Pro?


    Thank you.
