Thank you for all the information. These orchestra VSTi are fantastic if they sound like the demos I listened to. I guess the sound quality depends on the Pc sound card and that playing live properly depends on the processor and the RAM of the computer. My Pc is an Athlon 64 Dual core 5000+ ,4GB RAM (Windows XP) with a soundblaster X-Fi Xtreme Audio so I think it's good enough for this purpose.
But something else attracted my attention: Someone from Liontracks offered me for a good price a used Mediastation X 76 which is in my country and I got so excited I couldn´t think about VSTi’s much more. This machine looks awesome and its features are impressive. Actually it is computer (that most of you already know)with the console of an arranger with 76 keys and many useful sliders and buttons and an 8.5 inches touch display all comparable to a Korg Oasys. I’ve read some comments about the better quality of sounds of the Oasys but it is not available here anymore (because I think the production stopped) and I wouldn’t pay a fortune for it. With the Mediastation I would be able to use any VSTi I want having the control of everything at the tip of my fingers, I could also play Yamaha Styles and get rid of my Psr 1500. I don’t know the quality of the keybed and if it has aftertouch but surely should be better than middle range keyboards like the ones I have (the PA500 keybed is awful). Well I wanted to share this and say thanks to this forum which allows me to learn and also opens the door to unexpected opportunities.
