Thanks guys!
Well I'm very happy with Hypersonic... The only thing I'm complaining about is the pianos.. they don't sound right. Allthough you can get some decent sounds by tweaking them.. but all in all I've heard much better pianos elsewhere.
When it comes to the megavoices, I've managed to create megavoice compatible guitars. However, since you can't add samples to Hypersonic, I've haven't gotten them 100% compatible. I'm currently working on creating megavoice compatible sf2's as a workaround. Maybe I'll build a whole SF2 library of sounds to use instead. I'm not sure.. will see how much time I get to play around with it

I've posted another example, this uses the other Christmax Swing style from the Tyros.
