chony, my hope is that you stay with it. It takes some effort to get each particular system up and running. Once you have done so you will find it very very very very reliable. I have no failures on my system for over a year. Keep in mind I use my music computer only for music.....and nothing else. This helps...I think.
Kontakt 2 still has some issues. Once we get the v2.1 in Q3 things will likely work a whole lot better. I will use Kontakt 2 as I did Kontakt 1.5, i.e., for my lead voices. I load 8 to 10 voices on separate channels and call up different instruments from my keyboard by just changing channels. My jazz setup might look like:
Channel l Organ
2 Flute
3 Trumpet
4 Sax
5 Strings
6 Piano
7 Vibes
8 Jazz Guitar
For the Auto Accompaniment I use LiveSynth Pro & modified sYnerGi GS wavetable.
My Computer is homemade standard PC:
3.02 GHz, 2GB RAM, 2 80GB 7200rpm HDs
2 sound cards Audigy 2ZS Platium (midi in/out) & Steinbergs VSL2020 (audio)
Windows XP
There are some members on the Kontakt forum experiencing similar problems as you have. I too occasionaly get hits where the CPU usage is up close to 100% but things settle down and I can play. I will use Kontakt 2 for live performances.....but it is not quite ready for prime time.....a little risky. I am not worried I just swing over to Kontakt 1.5 if things don't work out.
Here is NI's phone number but you may only get a voice mail box (not a live human):
323-467-2693.
East West Soundsonline: 310-271-6969
I find at this point they are not to willing to talk to customers. They don't have all the answers nailed down. Over time they will get it right. They have a whole lot of important rich customers....Hollywood.
I think one of the problems of CPU usage is their reverb (convolution). This can bring down even the most powerful PC/MAC. Try turning off the reverb. I use Cakewalk's Sonitus effects. They are not nearly as good but don't bring down your computer. Sonitus effects are a whole lot higher quality then what you will find in keyboards...even better than the best...Yamaha.
If you are using a laptop you need to use ASIO drivers to keep the latency down. An external soundcard and HD would be very helpful. You should keep all your samples/instruments on the external HD (8mb Cache & 7200rpm). You should beable to keep your latency to 2.9ms.....10ms or less is preferred. As I said ASIO drivers should help in this regard:
http://www.asio4all.com/ Oh, it just occurred to me that another place where things can go badly wrong and that is with their Quick Database. Kontakt needs to set this up initially and most hosts don't wait around long enough and causes the whole thing to crash. Try running Kontakt as a standalone until it has the Quick Database setup (Files/Folders/Drives for the samples and instruments). I would just as soon they give up on this feature. I can find my instruments and samples on my own...quickly. GigaStudio had problems with this as well. I don't know whether Kontakt has a problem with this but when I started out it shut down my host pretty often.
I hope this helps. Just don't give up. You will be reward with magnificent sound. As an example of a perfect Jazz Combo:
Scarbee/Colossus Bass
Bardstown/Steinway D Piano
Bardstown Jazz Guitar
Colossus Drum kits
The Drum Kit From Hell are considered the among the best but they may not be GM compatible. I would give the kits in Colossus a try first. The Bardstown Bosendorfer 290 is just great...I use it all the time. The Steinway D which comes with Colossus is also excellent and I would stay with it for starters.
