Help!

I can't for the life of me work out what I've done wrong but I can't 
get any of my exs sequences to play back despite being able to 
play them and record them normally from the keyboard. I think 
maybe I've hit a key command unknowingly and toggled some 
playback switch. When I press play the little midi meter next to 
the track shows activity but there's no audio output. All other midi 
tracks play back normally.

Any help would be gratefully received
