I love mine (S88). I like the ease of programing voices, performances, sequencing and sampling. The SRX board options are the best of the rompler world. The keyboard action on the 8 is very good. Skip back sampling works quite well.
I've had Triton, Motif & Karma. This board is great for people like me who don't like sequencing.recording with computer software.
Bottom line for me is Zero brain damage when recording. Nothing gets in the way of creative inpulse. Very inspiring.
