Now that I have a computer that can handle anything for audio I decided to start using GPO in Sibelius, the results are Awesome! Really impressed! I just composing a string quartet in Sibelius using GPO with out any keyswitching, just slurs, cress, dim, and dynamics, and it sounding very realistic. Before I would have to load up the midi file in Sonar and bust myA** to get it to sound good with mixing and leveling and all the other production stuff, now though I am just playing it in Sibelius with great results.
Are others using Sibelius with GPO how are you using Keyswitching? I just started testing this out so really I am fooling around writing a vienna style string quartet. My instruments are first solo violin, second solo violin, first viola solo, and first cello solo.
