Waist of money for the EX8 if you only plan to use the sounds out of it or if you are not a die-hard keyboard player but read on..........
I have a motif es8 and I have NEVER touched the sequencer in it and hardly touch the knobs on the thing in the studio.
I hate the weighted keyboard for beat making becuase the feel just isn't right. I use the ASR-10 keys for midi triggering. I also have a MPK49 that is useful for triggering. I also have a MPC that I do not sequence with either becuase it is so much easier doing it ITB but again, I use it for midi triggering and roll.
I do LOVE the sounds in the XS but really most of the sounds can be found ITB now-a-days. But I must admit that for the hammer keys, the XS8 is hard to beat and it's a good investment if you do not have a solid weighted keyboard controller. (If that's your thing)
What I love about workstations is taking them to do live performances. (Keyboard Player)
Just giving you another perspective.
