"How do I connect Roland TD-17KVX electric drums into BandLab to create drums with my band? I was told by our band coach that I plug my drums into a interface which is hooked through my Apple iMac com via USB". I did this. No signal in BandLab when I strike a drum pad to test if input signal is recognised. No luck? I connected the drum module via 2 cordial cables for right/left stereo from back of drum module into front of Interface (Presonus 68c) - (Mic/Inst/Line) 1 and 2 ports. I receive a signal in the Studio One 5 software (came with the Presonus Interface, but not in BandLab. I do see the my Interface in BandLab at bottom left side when I go into new project, but not drum signal? What am I not doing correctly? Your assistance with this is greatly appreciated..
