I also must say, I disagree with these technologies being more difficult to play. On the contrary: with those sample modeling instruments I get an immediate and very versatile playing experience, that is impossible with normal samples an a lot of key switches. The only drawbacks at the moment are indeed the CPU usage, the lack of strings, generally the lack of available good quality instruments.
Those pure PM instruments, like Wallander for example are in my opinion sonically not up to the point. This becomes obvious, when you wish to use them rather dry ... in that Sample modeling is the first and only competitor, offering great orchestral instruments. There are great saxes, a trumpet (which also works great in orchestral style in my opinion) and and upcoming trombone and solo strings. The company is rather small though, so development is slow - enough time for VSL to catch up! :-)
I really believe that this is the future. Some years in the future a software based pure sample playback won't stand a chance - especially with those rather high prices! We have to remember, when VSL came out it did already break some limitations of sampling: First the interval legato and repetitions, which has become standard nowadays, then the Vienna Instrument software with speed detection etc. and finally MIR. The next step MUST be a new Vienna Instruments software with the next revolution: Transitions between samples (take the AET in Kontakt 4 for example, even if the sample modelling technology is far better!), playable and realistic pitchbend-, vibrato and speed (e.g. tremolo or legato transitions - only sample modelling offers that sounding like the real thing), Mircro tuning, etc.
I know, that is gonna be a hell of a lot of work on so many samples and many sample in the library (e.g. crescndos) might become almost obslolete. But if VSL wants to keep the pole position, it will be necessary. Finally, all of us want to do music and have a great time doing that. And what playable instruments have is simply so much fun playing! Almost no editing, no constructing ... This is almost the most important factor for me, because i spend a lot of my time doing it and wanna have fun!!!:-)
