Hi Rikki:
As a former Technics KN5000 owner, I totally concur with what Bob said. I loved how my KN5000 tracked even the more exotic complex chords correctly and so smoothly.
When I switched to Yamaha (following Technics regrettable demise), in order to still play the more complex chords,
I subsequently had to switch to playing in split mode, assigning both left & right voice to the same piano voice,
but with the chord recognition only recognized from what's played with the LH,
freeing the RH to play chord scale notes & alterations (#9,b9,#11, etc) & passing tones without it negatively affecting the auto chord recognition,
of which Yamaha's 'full keyboard' mode often results in.
Over the years I've learned to accept that limitation, but I still miss Technics' superior full keyboard chord recognition.

I really love my Tyros 4, but one IMPORTANT advantage that the Korg PA3X has over Tyros 4, especially for us piano players,
is its far superior 'full keyboard' chord recognition, which I feel runs a 'very close' 2nd to Technics.

Rikki, I'm really looking forward to learning more from you about your PA3X as you discover and report to us about its many features.
I'm especially interested in hearing more about the "Songbook", new "TC Helicon Vocal Harmonizer" and as you probably predicted, it's new "Chord Sequencer" feature.

When Nick and I met last weekend, we noticed how people in Australian & California West Coast both seem to share a similar casual relaxed lifestyle.
Whenever I can make it down to Australia, I'd love to hook up with both you and Nick.
