I'm fairly new to Garageband. I'm recording a song with about 15 tracks and been able to play back and edit no problem. When I reopened Garageband to continue editing today, I could only hear those tracks that had some reverb on them. None of the other tracks could be heard (I checked the volume on each of them and that they weren't in silent mode). If I add reverb to one of the tracks I can suddenly start hearing it - its as if the reverb control is acting as a volume control! Any ideas what it could be? I've gone into other songs I've recorded and they are all working fine so it seems to be a setting on the current song. I may have missed something really obvious but I don't think so. Any suggestions welcome - thanks!
