Just a little update: the main page is still password-protected, but all of its subdirectories are not. Take any 3.0 Library link, swap the three in for a four and voilà:
https://www.nordkeyboards.com/sound-lib ... y-40/synth . Piano 5 owners should definitely download any sound they miss from the old library before they lock these webpages down too!
It seems like Clavia's halfway through with the work: most of the synths and part of the orchestral sounds are ready. Guitars haven't even been uploaded yet, the Mellotron collection only consists of two sounds for now, whilst many bass, string, organ and keyboard samples haven't been updated yet. Frankly speaking, since it's a huge work, it would be a feat in its own right if they managed to keep things on schedule (they announced the new sample library for the Piano 5 would be ready around Autumn).
Still, I really can't see how some patches can benefit from the new format (and the increased weight, some samples are literally twice as heavy as the current one), especially synths (from the sound demoes, it doesn't look like they re-recorded any synth or acoustic instrument, nor added anything related to round-robin effects). Incidentally, I hope they'll use the opportunity to revamp some forgotten but quite useful sounds, like the RMI and Planet pianos (no other keyboard on the market features those sounds) or the old hidden synths collection page.
