Hi all, new here! Im after some help, ive recently bought a TD3 and ive manage to sync the clock etc by usb, it plays and records midi fine, but I can't seem to edit the midi or even make my own riff, it just plays what it wasn't playing before over the top, Im not sure if its something not programmed on the tb3 correctly or Logic Pro X. I have seen people on YouTube playing through there midi keyboard and also editing riffs on logic, but im stumped on how to do it. Thanks in advance for any help, Aaron
