I think nearly every company is promising "NON-OBSOLESCENCE" somehow when it`s possible to load a new O.S. via disc drive. (maybe a marketing gag?)
I dont know what you think, but I dont believe them. (I´m a strange man, I dont believe everything the industry tells me, not only in music matters) If this "NON-OBSOLESCENCE" would be a principle of industry on this planet my old VW BEETLE from 1964 would be still state-of-the-art.
For a very long time I was playing the GEM WK 4 (1996) and the dealer was telling me of "NON-OBSOLENCE" because it was one of the first keyboards to be updated via disc.
O.S. update developing for this keyboard stopped 1998!
If the "NON-OBSOLESCENCE" of the X1 was the naked truth, the developement of the SD1 must be a big mistake. Why should they develope a new instrument when the old one will be the "state-of-the-art" for the next 20 years. Maybe because the hardware and processor possibilities are changing like at the computers?
The current O.S. version of the X1 is 4.0, so there not only were "smaller upgrades".
Can you imagine what happens if the X1 would have the same possibilities as the SD1?
Maybe the X1 will explode because the processor is to slow.
The last 10 years the music industry is developing faster and the competition is growing harder. One reason could be the possibility to update a O.S. via disc. This leads EVERY company to faster presentations and I dont now ONE SINGULAR instrument which is working perfectly from the O.S. Version 1.0.
(By the way: The latest O.S. for the PSR 9000pro still was not solving the timing problems when playing a midifile. Maybe with a new update coming 2006, because as you said it`s a regular feature at professional instruments).
