I received my (slightly used) Analog 4, MKII from a guy on Reverb.com on Saturday. I happened to be trying to fix my doorbell (so I wouldn’t miss the UPS delivery, which required a signature for such an expensive item), when the UPS guy pulled up. A few hours later (my girlfriend was insistent we do a few other things while I very distractedly complied), I open the delivery box, find the A4 box inside, and the A4 all neatly packed away, barely used as described. I connect it up to my system, fire it up, and it hangs… on the intro screen. No Christmas lights, no flashing, just a mostly dead screen. Um… (ffck), what? I take a video with my phone in case it needs to be returned. I turn it off, then on. Works. Good. Fiddle for a while, then leave. Turn it off. Come back. turn it on. Works. Yeah, turn it off, then on, doesn’t work again, hangs, keeps doing thus (sheeeeet). I come here, see that several other Elektron gear do this with the 1.50 OS update. Fire up Transfer, update the system (very easy to do, especially for Elektron), problem solved! Looking for how to get to factory reset, wipe out the other guy’s stuff, get a clean machine, not easy to find, still getting my head around using this machine, but always I remember having some strange frustrations with my Model:Samples, which turned out to be easy to use, once I gave in and just read through the manual and gave myself up to a very different way of doing stuff. Keeping that in mind now, as I slowly unpeel the intricacies and weird, wild and vast universe of the A4, MkII. Still wish there was a good, straightforward set of videos on it (something like what there is for my MatrixBrute and my Wavestate). I can’t find any, after searching here, and everywhere. just bits and pieces, and silent videos with no talking (not great). So, I’ve printed the manual, and will keep it handy form my new dip into Elektron. Super excited.
Congrats. Have a look at Thavius Beck’s always great tutorial series for MacProVideo:
Only a few are free and you have to pay a smallish amount for the whole series.
Otherwise Cuckoo is usually good for getting the basics down in an easy to follow way. Or else, others have done A4 tutorials for different aspects of the synth. It has many possibilities so there’s a lot of stuff out there. And, of course, RTFM multiple times 
There is a limit of five free views per day on the Thavius Beck series. Since five is more than enough fodder for a while, this isn’t really a problem. Other good videos from Gary P Hayes and Ivar Tryti.
With Cenk.
@craig and @plragde, thanks for the quick responses. I have looked at Cuckoo’s stuff (he really helped me with the Model:Samples), and he’s such a treat to watch anyway. His exploration video is for the MK1, and he doesn’t have anything for the MK2. I know the engines are pretty much the same, but the button layouts seem to be very different. Maybe not.
@Tchu, yes I watched that video before even getting the A42, and will plan to watch it again later–that guy is so intimately familiar with the gear that it is hard to even know what he’s doing sometimes, but his familiarity and music are inspirational.
Hah! I didn’t even think to check out MacProVideo. I used it to learn MatrixBrute with Marc Doty, very helpful. I see, though, that this is for A41. Maybe it will all still make sense for the A42
The MKI and MKII are extremely similar imo. There are just a few extra quality-of-life buttons and shortcuts added to the MKII (and a way better screen, ofc). The thing is that lots of YouTubers who already went to the trouble of producing quite lengthy tutorials for the MKI are not likely to want to go back to basics again with a MKII because they cross over so much. The principles behind using the MKI will easily translate to the MKII. When I was learning OT MKII, the MKI videos still helped 
Don’t mention His name, we’re still crying
Good to know. Thank you. i will go back and watch these videos, while also reading the manual.
One thing I did find helpful with the M:S, was to disconnect it from everything else in my studio, go somewhere else (e.g. my cabin) and sit with it on headphones and the manual, and just focus on that, without the distractingly temptations of using it with other gear, until I mostly figured it out. I did this last night with the A42, took it downstairs and sat with it alone, with printed manual in 3-ring binder next to me. My process, “old school” for this “old guy.”
Although others say AR should be my next Elektron purchase, I am thinking I might end up getting the OT2 after familiarizing myself with the A42. I know it doesn’t work with Overbridge (yet), but using Overbridge with the A42, I didn’t really get excited about it (trying to get away from my computer anyway).
OT is great (as is Rytm). But I would forget OT ever playing nicely with a computer other than simple midi related things. OB will never come to OT unless they release a brand new OT (which probably won’t happen either TBH). Anyway, the A4 is plenty complicated enough to keep you occupied for a good while before you think about getting more Elektrons. Push it as far as you can!
Yes, that’s what I am thinking, focus on this. Plus I have an MPC One that I have yet to fully integrate into my system and this might do quite a bit of the duties of an OT, plus has some other options that the OT doesn’t have. So, with the MPC One as the connection between the rest of my hardware system (hardware synths on one side) and the A42 and M:S (on the other).
