Fran, the PA1000 can display SMF chords. You just need another step which is very easy. Load the SMF in the sequencer, press menu button, tap song edit, tap utility, tap detect chords and save the SMF. It'll display chords on top of the words at the right time. It can also display in score format. I love it.
I love the E-A7 but I need to add a vocal harmonizer whenever I use it. The PA1000 is my all-in-one AKB.
