I had similar thoughts some time ago, when I had Octatrack and also other gear connected to it - I felt too distracted and I was spending too much time studying stuff instead of making music. Then I started to do a research towards some piece of gear, that will be the most versatile, e.g. have drums and synths and multitimbrality all at once, and not be too heavy with usage. I hate touchscreens so MPCs didn’t make it to the list already on the beginning :).
MC707 requires a little bit of a study, but doing that in parallel with Roland’s YT tutorial and later going through some vids related to software updates is imho enough to start having fun with music creation. Even if Roland’s approach has many drawbacks (e.g. you can’t save your own preset sound, you can only store it under clip or project and reuse it later, or no pattern queing in a Elektron style but pattern change on predefined number of bars regardless of the actual pattern size) it has some advantages which Elektron does not have (…and I’ll be banned on this forum for saying this ), like track cueing to headphones - so when jamming you can work out a new sound and phrase on a track and pre-listening on headphones while not disturbing your main mix.
I was almost about selling my A4 and DN and stay only with MC707 to keep the setup as minimal as possible, but I realized many sounds (typically FM ones) are not achievable on MC707, and there is no p-locking which I got used to a lot (well, you can record knob movement as automation, but that is far from p-locking) and no trig conditioning, which is the second one I’m using very often. MC707 is best for recording on-the-fly (from MIDI keyboard for example) while Elektrons (even if live recording is one of the features) are best with programming - but just my opinion :).
