With Finale also in tatters, Notion really leaving a great lot to be desired for proper symphonic scores, LilyPond cumbersome, and most every other company barely able to accomodate the confounding complexity of a Hans Zimmer cue, I tell you VSL, NOW's the time to get into the game.
Who else is going to absorb all those hundreds of thousands of desperate users?... Lots of moneyyyy!.... Don't forget. Maybe after Finale goes (that's not a wish), over a million users who DON'T compose on the piano roll (or by importing others' loops and Scorephobia cues) are going to scavenge for a professional, no half-arsed, notation solution. Be there first, and with the advantage of seamless VI-MIR integration you can really charge for the privilege. No House-Styles, no setting up. It will be so worth it!
