They probably do, and it's not surprising. Present marketing mantra is that time to marke is more important than product quality, and not just when it comes to keyboards. I have a car which has received a third recall notice. Software is routinely released with defficiencies, and you are forced to download patches from the manufacturers' web sites.

So I think that the fact that Tyros 2 has had only one minor software update is more of an abberation rather than the norm, and the trend to be expected is that you will have to install software updates.

In a way by putting the operating software into rewriteable memory, manufacturers are doing us a disservice - they take it as a permission to release half-baked instruments with the intention to patch them up later. The upside is that the software upgrades may also add new features - look at Ketron, Korg, and Roland - all of those had added features with the major software upgrades.

But if you are an early adopter (buying a keyboard shortly after its release), you should be prepared to be a beta-tester, and live, at least temporarily, with the half-baked machine.
