purchased zoom r8,about 10 yrs ago, it came with cubase le 5,couldnt use it then,pc not powerful enough, I have one now, installed the software,and set up device drivers, inputs and out puts are shown. Program does not pic up mic at all. also when i imported audio, no play back sound. Mic and speakers are working on pc.
