Hi Rounik, Thanks for your reply. Yup, I got the time wrong! Try 05.59 - sorry about that! After quantizing, in the event list, there are 12 events all at the same time, midi channel and control number and info columns. Only the value is different, varying from 29 to 38. Surely only one of these can be the node? I'm probably navel gazing here, or else I'm missing something and soon the penny will drop and I'll be begging you to delete this question! Cheers.
