I am trying to record some music from a cassette I have to my computer to clean it up a bit before transferring to CD. I am using a mac powerbook G4 with an Alesis Multimix firewire 16 channel mixer. I have the cassette recorder patched into the multimix and can monitor the cassette through the multimix. My DAW software is Cubase LE 1.8. I have followed all the instructions for setting my audio preferences on the mac. I can see the audio in the bar moving in sequence with the audio. When I try to record it in Cubase I get nothing. I have also tried recording with a microphone and actually was able to get a visual waveform in cubase but could not play it back. Any suggestions? PS: I also downloaded the audacity recording program and get the same results. It seems to be a mac issue.
