Worth checking out if I’m mainly a sequencer type of person and don’t finger drum?

Been watching a ton of videos about the 404, and have been interested in trying it out.

Is 404 still approachable for someone like me? From the videos I watched, it seems you can’t edit steps after that placed? Just looking to understand the limitations a littler better
