Thanks for that Brach, I solved it & am slightly embarrassed that I’d didn’t work out the problem before, but I did what you suggested and it does enter calibration mode fine, that wasn’t the issue. I realised that it was probably still in omni-channel mode, so I simply sent a CC#124 message on midi channel 2 and this has fixed it, it now responds perfectly on channel 2 alone! Now all I have to do is get it integrated in to my board and it’ll all be great! Thanks again for you attentive reply.
