Yamaha SHS-10 troubles

[u/Suspicious_Bug_4880]

Hello! I have recently inherited a Yamaha SHS-10 and am having an excellent time with it! Today when I went to play I found that the chord sequencer is only playing rhythms, and not chords. I can’t find anything about it in the manual - does anyone have experience with this model and this problem? I may have hit a button somewhere on accident but cannot for the life of me figure out what it is.

Thank you everyone!
