I have a song I am working on and I am needing to send the stems to a friend. The problem is every time I export stems it only does the synth and software tracks, my guitar tracks have no audio when exported. I have done the mixdown and it all works fine. I am using guitar rig with on my guitar tracks if that makes any difference. Everything does export as a stem but the audio files (guitar and vocals) have no sound when exported as a WAV file. Any help would be greatly appreciated!
