If you dont have a decent built-in sequencer
and you find computers "cumbersome" as I have
it may be a good Idea. finding your style of
working is prime. Many still swear by their
Alesis MT. I use the seq. in my ASR-10. There are "better" ones, but, it fits my style of working because it limits my choices
thus freeing me to get on with creating music. Best of luck in your quest!
