Being an actively growing (teenage) musician with not much money and just a CTX-5000 (and not much else), I have a fondness for CASIO products. At the moment I'm looking to upgrade to something like a Yamaha MODX6 because there just aren't any CASIO keyboards that fit my needs as I advance that are also at that quality level. This is one thing that has kept people from taking CASIO seriously for a while. They don't have any flagship professional instruments. They do have some really solid semi-pro keyboards/synths that are great, like the CTX-3000/5000, but not much beyond that. The discontinued MZX keyboards go a little bit further than the CTX line, but that seems to be where it stops. I'd love to see CASIO release a solid line of keyboards on a level of at least the MOFX or MODX keyboards, but especially on the level of the Montage. If they build off the AiX sound source, I could see this being possible.
I believe that instruments are only half of the equation when it comes to music, and that the player is just as important. An amazing musician could make an entry-level keyboard sound like it's professional by taking advantage of what it can do, instead of restraining because of what it can't do. I think elitism, especially in music and instruments of all kinds is foolish and destructive. Even if I became an exceptional musician one day with the best keyboards and the nicest equipment, I wouldn't look down on someone who is just starting to explore music and their own sound with the best that they can afford; if that means a $350 CASIO, more power to them. Who knows what they'll create.
I digress. I love bikes and work at a bike shop, and I started out mountain biking on a $250 Walmart bike. That bike was terribly built, but it lasted me for at least 500 miles, a few adventures, and some tough trails. When I finally had enough money and skill to justify a much better bike, I didn't just toss the old one out. No- I took it apart, down to the frame, and rebuilt it the best I could so it could last another 500 miles for someone else. Never forget where you came from.
That's just my two cents.
