I am preparing to do a musical theater tour where I need to use samples to cover the brass and extra percussion in the pit, and they have to be played live. I am looking at the ProjectSAM Brass and True Strike percussion, and am trying to figure out the best setup to use these VSTs. Can Halion be used live and be stable? Can you layer and map sounds to a keyboard through midi? How bad is the latency? Any suggestions for other programs to use?
