So, I'm starting to use the Pa4X at my church services. I have been a contemporary worship leader since 2004. I use backing tracks that I create and I'm using the Pa4X to playback MP3s of the backing track during the service. Today I wanted to add some harmonies while playing piano live over the track and singing into the mic... I get reverb but no harmonies!!

In Song play mode, the chords show up in the top bar but the harmonies can not read the chords. I go to Style play mode and it works like a gem!

Am I missing a setting?!? Help!!!
