problem with midi track

[cvp79a]

i've been playing around with this coldplay track, which sounds fine when played through my pc, but when i put the disc in the cvp79a clav the drums sound 'funny' - sort of unevenly rhythmical. anyone want to try and listen and help?

a link to the file is given below

many thanks, graham
