Yes, learning two boxes at the same time, kind of makes my head explode a bit, so i panic and feel like getting rid of one in favour of concentrating on another, i still can return it so would be easy…
But, i’ve just watched this video, and it made me realise how cool the A4 is and how good it can feet in what i want to work on!
EDIT: tried to embed the video, but it goes crazy and embeds 10 copies of it after each other or something! The video was “Elektron Analog 4 Tutorial #1 - Oscillators and Velocity Mod.” from SecretMusicUK.
The idea was to put together minimal hardware setup which would cover lots of ground and last for years in terms of staying actual sounding and deep enough not to get bored from, and looks like analog offerings from Elektron are the best bet with the Overbridge coming and all the functionally they’ve got already, plus, who knows what the upgrades will bring to the AR, hmm 
I think i will try to calm down, put myself together, stop to panic and methodically, step by step learn my new gear, and if i want just to bang some stuff i always can lock the A4 and play with AR only,hehe.
Oh, and the mixer question from that other post: as i’ve said, i wanted to have minimal setup, like two boxes which wit into backpack, so yes, portability mostly, plus i’m planning to use laptop for mixing duties later when Overbridge will be available. And it is fun to plug these into each other, i can plug A4 into A4 for compressing all the stuff together, and still can use individual outputs of AR to send signals into A4 for some additional processing if i want, or even use the beats as a source of some voices for some complex rhythmical structures…
Guys, it is a great discussion, you really help me all to figure out things here.
Sometimes you just have to let it out,hehe.
Thanks!
