Did not find the entry I just posted; Gotta do it all again? UR44 chnls 1 thru 4 show audio being received by Mac Audio Prefs. Mac Audio Prefs In/Out show UR44. USB used as interface between Mac/UR44. Mac/Logic ProX Audio Prefs shows UR44 as IN/OUT. On any Logic Pro Track, only UR44 Chnl one (1) is getting thru. Nothing from UR44 2, 3, & 4 Chnls. If no one has a solution, does anyone know how to contact Steinberg Support directly?
