[LAD] Has anyone ever played a plugin in realtime ... [related to:] hard realtime performance synth

Has anyone ever played a plugin in realtime ( live )... ...and I don't mean a one-finger melody, but a mutli-polyphonic piano piece, eventually with sustain held down, which resulted in about 20 to 40 simultaneusly processed voices. I just realized, that I've never been able to do that. Neither almost. Frustration. But on my digital piano, I can to it. That thing is some years old and definitely doesn't have 2 x 2 GHz processors available. Anyway. The answer so far has been: That system is more dedicated, thus it can, while my PC cannot. The conclusion: I'm working with a wrong system ! - It doesn't allow me to work the way I intend. Damn. What did I buy this system for ? I don't need those 2 x 2GHz for word processing - right ?? This makes me wonder: Which one is the system for my requirements ? Which one is able to make some softsynths / samplers process 30 voices in less than 9 milliseconds ? Could my system be extended or modified in order to suit ? How then ? We have dedicated hardware for graphics, why not for audio ? Sincerely -- E.R.
