Disklavier

Rob,
I have the DCD1 and DSR1 arrangement on my MX80 upright and am 
pleased with the output. Yes, there are only 200 titles that are DCD1 
compatible, compared to the 500 plus titles for the Mark IV but with 
the 20 PianoSmart titles I now own, I've got at least US$600 invested 
in audio CDs and accompanying floppies. There may be 8 or 10 of the 
currently available DCD1 titles that I would purchase and if I could 
choose from the full offering that total could grow to maybe 60-70. 
Over time, I could ease those additional titles into my collection at 
a pace that would not threaten my marital relations.

I know that the selection is what you are really concerned about but 
at 500 titles available for the MK IV we are still only talking about 
an extremely small percentage of the total music that is published. 
And within that selection a lesser percentage of what anyone would 
find to suit an individual's taste.

I view the PianoSmart as an enhancement to my repertoire, as much of 
the time I really only want to listen to solos and ensembles. Many of 
my titles do not lend themselves to allowing the piano to be the 
featured instrument and have been an expensive disappointment. 

As I understand it, there is little chance of the smarts that allow 
pitch bending of the audio to A440hz being offered as an upgrade to 
the DCD1. So the real question is: Are the tens of thousands of 
dollars that an ungrade to a MK IV worth the additional selection of 
300 titles? Not to me. My budget just can't stand it. My 
unenlightened guests are thrilled with my old MX80 right now, as I 
am. The DCD1 compatible titles are constantly expanding, and will 
probably keep me satisfied until used Mark IVs are within my budget. 
Just my opinion.
Fred
