i think it is hard going from a consumer Synth Producer to professional users but i think PX5S was a milestone for Casio bringing to the market some unique Stage Piano with an amazing Piano Sound a given Synthesizer inside for less and some other gimmicks, of course some things are not so good an could be fixed with updates but so often updates are missing after 2 Years and new hardware must be given to the users what really impressed me from the beginning was the Support of casio the firmware update possibility and still till today i feel the best synth or stage piano is the one with an software to be updated time to time, how o wrote before a modular synth with hard and soft updates are the future , now we see the MX-Z very nice very funny but ,.,,,not the non plus ultra Arranger i think all the other brands play in a category with it , for example an italian Brand made the VIVO Stage piano from scratch and it is a killer there is unlimited polyphony 320 Oszillators 15 seconds of true sample withou loops and a mix between AI and Synthesis this Brand will be a Killer Brand in the future believe me and they do invent !" so i think like the new Yamaha Monatge ...going to be a leader today need s to bring innovative products.... like the PX5S was from the IDEA too the price....i don't feel to spend 1000$ for an Arranger ,,,if i own other synths like the old S03 still ginning me amazing sounds as a background GM /XG player ...maybe i will wait for the next real Casio Synth or Rack clearly Innovative like the Hybrid Piano ..... but of course Piano is a nice Brand and still Love what they do ..
