Since allmost 2 years I am a happy A-88 owner and just love the feel of its action.

VPC1 migth be even slightly better though certainly not twice as good. But its allmost twice as heavy as the A-88.

Cheers

. . . One big issue though is the tuning of the Casio is inconsistant.  Some intervals are good and others aren't.  . . .

Have you ever checked the tuning with an automatic tuner ("guitar tuner") ?  There's a free app  -- DA Tuner -- for Android phones, if you have one.   It'll take about five minutes to run through a chromatic octave, carefully.

When I did that with my PX-350, every note was dead on pitch.

If a 'master piano' (one to be sampled for a DP) is mis-tuned, the tuning would be "fixed" by an audio engineer, after recording the sound, but before loading it into the DP's memory.

Any chance you could explain that in your own words, in case you remember? What they could possibly mean?

Approximately;  There aren't enough variables to adjust to get a "good" tuning, i.e. there is a master frequency control that will provide some variation around A440, but very little else.

I am NOT a piano technician, I am NOT a sound tweaker.
As a player I merely "read around the edges" of piano tech.

Pretty obvious isn't it? He means what he said, that the tuning jobs performed on pianos before they are samples are usually not very good quality tunings.

There was an article in the technician/tuner section of pianoworld that discussed tuning of electronic pianos - general opinion among piano techs seemed to be that the tuning of most digital pianos is BAD and there is little or nothing that can be done about it.

Just WHAT?!

Something lighter and with on board sound. I'm okay with my Casio PX-150.  In the end what bugs me the most about it is that some intervals are very slightly out of tune.  Most people probably wouldn't notice it, but it certainly would be nice to have an electronic instrument where each individual note could be tuned, and then locked. I'm not quite sure why they don't have the tuning just right, but even the DX-7 was poor regarding "stretch tuning" It was in tune with itsef, but not necessarily with other instruments.  On the subject of the KX-88, one time I turned all the leaf springs upside down to stiffen up the action a bit.  It doesn't matter which position they are in except that I think they probably get weaker over time hence turning them over makes them a bit stiffer as the curve of the spring is in the opposite direction.  Basically the spring is just a flat piece of metal that is sprung into place.

I actually VALUE the mass of the KX88, it has a feeling of HEFT to it and I suspect that lighter weight boards wouldn't give me that.  Again,, I don't gig

Some think that is GREAT, since it is part of what keeps acoustic piano owners from migrating to the dark side

Many years ago I had both a Yamaha KX88 and Roland A80, and I much preferred the KX88.
I thought the Roland had far to noisy keys, and I still hanker for my KX88 played on by Jules Holland.!
However, times move on, and I am interested in peoples experiences/comparisons between the current A88 and VPC1.
Would anyone still get the KX88.?

I still have one, but don't really use it any more.   At the time it was OK, but always too heavy to transport.  I feel the Casio PX-150 is a better action.  I have no experience with the A80 or the VPC1.

Regarding the KX-88, it has a key that pivotes at the back.  There is a small leaf spring underneath and a heavy lead weight at the front.  The Casio action has no weights, but does have a steel bar that is somewhat balanced.  The front of the key pushes down on the front of the steel bar.  Neither have any sort of escapement which may not be necessary on any digital instrument.  Kawai has a fake escapement which is not an escapement at all but a silicone rubber nub that rubs on some other part of the action which gives the impression of an escapement, but it's totally unrealted to any sound output.

My opinion is that electronic pianos will eventually be superior to the accoustic pianos of the past.  In certain ways the sound of my Casio PX-150 is superior to my Chickering grand.  If  I was forced to give up one or the other, I'd let the Chickering go. One big issue though is the tuning of the Casio is inconsistant.  Some intervals are good and others aren't.  At least the Cickering can be tuned although curiously the bass notes sound sweeter on the Casio.  There is too much inharmonicity in the bass strings of the Chickering.
