Ok I've read the 2 page October 2005 Keyboard Player article by John Bates . He shares a few more details learned about Tyros2, after having a chance to get an in person sneek preview of it from Martin Harris, a member of the Yamaha Tyros2 development team. I'll paraphrase the highlights:
Super Articulation: This new technology actually analyzes 'the way you play' the keyboard and articulates the chosen instrument voice (with multiple samples per note) accordingly. Super Articulation Sax sound: No longer do you simply re-trigger the SAME sample every time you play a key. If you want to play an entire phrase with one breath you simply play legato. It will also recognise which direction you play in, how big the interval is and of course, note velocity. In addition, Tyros2 includes 'key off' samples, of which in the sax's case, produces a valve noise. For additional effects, remote foot pedal activation produces 'breath noise'. On Guitar sounds, you get the sound of the guitar body. String Sounds: You can hear the difference between legato & staccato which is dependant on 'how' the string sounds are played. Up to now, staccato/legato sounding strings have been patch selection (voice) dependent.
Here's another impressive example of the level of detail built into the sounds of Tyros2. If you bend the notes (using pitch bend) ONLY the lower note of the pair of notes being played bends. Authentic pedal steel emulation.
Many of the new samples were recorded in stereo, especially the guitars, strings and brass sounds. Though very impressive sounding sent out to 2 discreet L/R speakers, I suspect these stereo samples might be troublesome for people wanting to go out to a single channel mono speaker output like the Bose PAS.
Impressive newly sampled Organ sounds are also featured on Tyros2. Auto accompaniment (400 styles) have all been reworked and upgraded with a host of new ones added as well.
Guitar 'Chord Voicing' interpretation has been added. This means that no matter what chord voicing you choose to play on the keyboard, Tyros2 will re-interprete it and have the multipad section play the correct (for the guitar) chord voicing instead. The Tyros2 guitar chord conversion table not only figures out the correct guitar chord voicing, but the correct position played on the neck as well.
Another thing stated in this article is, in order to take full advantage of the new Tyros2 "Super Articulation" voices, the Tyros1 keyboard action has been 'thrown away' and replaced on Tyros2,by a brand 'new' 'very responsive' one of which is 'dramatically better'.
Ok guys, these are what 'I considered' the highlights of the article. If you want to read more, you gotta spend the $ and buy the magazine. The November issue of Keyboard Player promises a complete reveal (review). With luck, I'll have my Tyros2 by then, and will of course give you my report (and impresions) as well. In the meantime, we'll ALL get more information about Tyros2 when it officially rolls out to market: October 1st (3 days from now).
