1. As a pianist, I hate the keyboard of my new Yamaha PSR -SX900 without weighted keys. What should I definitely adjust in the settings of my Kronos X in order to take full advantage of the sounds, chords, rhythms and styles (including the variations) of the PSR-SX900 while playing and controlling via my Kronos X keyboard? In case I only use the excellent Kronos keyboard to replace the weak keyboard of the SX900?
2. Can I take advantage of the features and qualities of my Kronos X as a workstation via MIDI to take full advantage of the incoming styles of my SX900?
3. If I want to use the stereo speakers of the SX900 while on the road to amplify the sound from the Kronos X, what should I pay attention to or what should I do so that the audio settings on the Kronos are included in the sound reproduction as well as possible on my SX900?
Thanks in advance.

I've seen answers to your questions on the PSR forum:
