I have a rather simple chart in 2/4 time, slow, with C, E, C7, E7, Caug, A7, Cm, Dm, Fm, G, F, B7, Fmaj7, Fdim. I don't know what key it's in, but should that matter? I am using the iReal Pro symbols, not what I wrote here. It's on default instrumentation. It simply won't play the chords. It just keeps playing one chord. I de-installed iReal Pro, then had to BUY IT AGAIN. It still won't play my song. I did put a chord repeat sign within each measure--could that be it?
