I'll download it later and try it on my tablets.

For the moment, I can't see how the chords matter.  They're not particularly complicated and it's not as though MSP is trying to play them.  They are simply text, as far as the program knows.  I the problem is more likely to lie elsewhere.

Given that it has to recognise the chords so it can transpose them later if requested, I thought it might have got caught up trying to parse them, that's all.
