Hi, my brother and I can record audio (guitar via mic) onto a track however when we play this back via headphones and record a second audio track it records ok but includes the audio from the first track. Not only this but it adds a slight delay that increases through the song. The only way to stop it happening is to stop playback of the first track whsilt recording the second track (ie red cross on first track) but then we can't hear anything through the headphones. Is there a tick box somewhere that says 'allow play back of tracks to output only'? Can anyone please help? We're going mad trying to solve this one!
