I read with interest the responses to the OP's inquiry about the PX5s. I am in the market to replace a Kurzweil PC3 76 note workstation and have been steered toward considering this Casio, although Casio in and of itself is a brand I would never have normally considered. It's always represented a consumer-grade electronic keyboard, with one finger chords, built in drums, a recorder--something along the lines of Yamaha's cheaper DGX and YPG series boards. The thought of a $1000USD Casio portable board just didn't seem to mix. However as the OP, I have relentlessly pursued as much video and audio evidence of this keyboard's abilities and qualities (being in a location in which accessing it personally is difficult), and am teetering TOWARDS purchasing one, very soon. Question/Concern: 1. If any of you are familiar, even generally with the PC 3, you will know that it's a pretty sophisticated instrument and if there's a sound, effect or parameter that's not to your liking, you can get "into" this machine, shape and bend it the way you want, and save it. Frankly, I use it 90% of the time for its acoustic piano, and the other 10% for its reasonably authentic Hammond/Leslie abilities. What's the power of this PX5s in that regard: Can the parameters of, say, the acoustic piano(s) be entered into and user-adjusted (i.e. increase the treble, enhance the mid or bass)? Or is it what it is? 2. Occasionally I play bass in the LH and with the PC 3 I can dedicate a section of the board to emit its sounds separately through auxiliary outputs on the back of the board. I noticed the PX5s has only two "main" outputs, so that won't be possible. I can get around that IF the lower split part(s) can be adjusted in their volume, separate from the other layers and splits on the board. Is that possible? 3. How is the factory "Hammond" organ sound? Is it authentic? More importantly, how is the rotary "Leslie" effect? Dopplar like, or is it rich? I wasn't able to find any audio or videos of the organ stuff for any length of time. Thanks all!
