Topic: My Message to Casio:
Presently I have a PX-130, and a PX-150. Recently I purchased the Pianoteq software piano. The tone and tuning absolutely blow away the internal Casio sounds. I urge you to work with Pianoteq to produce a light weight sensitive Pianoteq controller keyboard that would have the speakers built in as is presently the case with the PX-1xx series. It would take the output from the computer, and at least have a volume knob, and perhaps some EQ sliders, with at least 1/4" output jacks to an external sound system for players in a large venue. MIDI output needs to be improved in terms of sensitivity.
