I am very happy to see a volume control capability added to the Audio Recorder function, in the Firmware Update for the PX-5S. Before the update was ready, I was surprised to notice that the fade out I had tried to insert at the end of a recording, with the volume control knob, didn't work at all. With the firmware update, it's a much better function. Over all, I absolutely love my PRIVIA PRO PX-5S which was delivered to my door on April 29, 2013. Finally, an authentic grand piano keyboard feel and sound, small enough to put on a table top, not to mention the synth functions etc. Thank you so much CASIO!
