Hi
Your problem is that you must have a starting point! If you go to STEP REC then to the actual channel and push the START-button in earliest position on the measure, then you have no problems to put in the ENDING. The best choice is to have such things on a CONTROL-channel. You can do this in the PART ASSIGN. I always use channel 5 for the CONTROL but you can take another, be shure to always use the same channel as CONTROL.
In a CONTROL-channel you can registrate almost everything exept notes!
Good luck
