Ive had both. Got rid of the AR, still have the TR8-S.
Well in terms of playing it, yes. TR8-S is way more immediate. Faders, knob per function, you dont need to select a page to tweak a parameter as you do on elektron stuff.
Setting up your kit takes a bit of time. But once its done, all good. Editing a variation while another one is playing is way cool. AR cant do that.
Sure, the AR wins on synthesis and weird sound design. TR8-S wins for speed of patterm writing and playability though. At least for me.
The sound quality if the TR8S is insane. With the AR, you are very dependant on the screen to know where you are. With the TR8-Sā¦ what you see is what you get.
