Fran, Bandstand is not ready for general live performances given it takes to long to load the instruments. This causes significant problems when there are changes in instruments in the middle of a style or midi file. The SGM180 would be a better choice until NI comes up with a smaller wavetable for Bandstand. For lead instruments there are better quality wavetables, e.g., Colossus, GPO, JABB, etc.
