Yeah, I've been wanting to reply to some of the stuff that was said. I hope
some OTHERS will comment about BOTH SCI FI soundtracks (I guess other
electronic/experimental scores as well), and HISTORICAL
ELECTRONIC/EXPERIMENTAL too -- which are most important to you, most
important influential to modern music, which would you take to a desert
island, which would you play to break a lease.

Is that what you meant to type? Pitch ascends as one moves from left to right
is counter intuitive? Last time I saw a keyboard....
