Thanks Christian, actually between your reply and a friends suggestion we fixed it.  Somehow I had inadvertently switched from internal sync to external sync as it triggers fine from my Roland MX-1 mixer. Set it back to internal and the key is fine, doh!
Sorry to post what now seems a silly help request, feel a bit of a dumb ass now
