One of my fave things with the Rytm mk1 is using the impulse machines to play the filter (crack the resonance up full and use the frequency to adjust the pitch), it creates weird and wonderful synth tones so it’s more than just a drum machine. Would love to get my hands on a MK2 and see how things like this interacts with the resampling capabilities.
I recommend importing a couple loops that work well together (rhodes and bass for example) and sticking those in on 2 tom channels so you have something to make beats to. 4 bar loops work well
The countless videos on the MK1 will probably cover a lot of the basics though as it’s not an entirely different machine. I got the A4MK2 during the week, I’ve never touched an A4MK1 but I’m still picking up lots of tips from older A4 videos, obviously the new machines will have more bells and whistles once you dig deeper though.
