Korg has been on the forefront of physical modeling research for almost a decade, and we're proud to present the fruits of that research in OASYS PCI. OASYS PCI includes models of electro-acoustic instruments, such as organ and electric piano, along with models of physical instruments, such as guitar, slap bass, trumpet, trombone, flute, saxophone, and even human vocals. Of course, traditional sample playback instruments also provide these sorts of sounds. So, why use physical modeling? Three reasons: expression, realism, and sound quality. Expression Physical modeling generates sound in real-time, by modeling the actual physical characteristics of the instrument and the player. This allows you to "reach inside" and play the model just as you would a real acoustic instrument, such as plucking a string gently or firmly, or blowing into a trumpet loudly or softly. Using this real-time control, you can shape phrases or even individual notes in natural, intuitive ways, for an unusual degree of musical expression. Realism Models respond to your playing in organic and sometimes unpredictable ways, just like real acoustic instruments. Pitch-bend the flute model, for instance, and it will slowly bend a bit, grow a little unstable, and then abruptly jump an octave. Play fast and loud on the trumpet, and the transitions between notes will sometimes include a subtle "blat" of instability; do a pitch-bend, and it "rips" through the harmonic series. Play hard on the acoustic guitar, and you'll sometimes hear a string "twang" brightly. These organic "imperfections" combine to give the player - and the listener - an uncanny sensation of reality. Sound quality Modeling also offers an edge in sound quality. For instance, modeling all 91 tone-wheels in an organ means that they are all precisely in phase, resulting in the pure, powerful sound of the genuine article. Use vibrato on a guitar, and notice how satisfying it is to hear a string "stretching."
