PES

Personally I would probably focus on the OT for some time, to really get to know it while making the most of it on its own (the more limitations, the easier to learn the little tricks).
But I would definitely get the A4 at some point. It’s the only Elektron box I’ve got (since just a couple of weeks ago), and it amazes me how well thought out it is.
The sound, to me it’s great. I’m glad the lows aren’t too boomy, since four of these voices are working together through stereo outs. As it is, the balance is good when using it on its own.
