mpc and copying sequences

im noticing that sometimes my 2000xl stops copying sequences sometimes...

like i wanna put 1-3 into 3-5 and the shit dosent register

wat exactly is the issue?

what's the exact process you use to copy sequences?

make sure when you go into edit that the TIME youre copying is selected properly and that the NOTES to copy are set to all. you also have to select your start time and form sequence to sequence to track to track
