Good to know re EAM. Re patterns: I can imagine, and as an applicant I'm unbelievably curious (rather, I think my "applicant" mentality hinders my ability to think rationally insofar as patterns are concerned, it seems). Thanks for the insight.
On another note (pun!), I take it you're not a musician. I mean no offense if you are (and I apologize for offending you if I have), but as a pianist myself, I feel hitting the right notes at the right times makes one a reasonable pianist, much like an auto-keyboard is a reasonable "pianist". But what makes a pianist great is not what and when notes are played (maybe necessary, not at all sufficient), but how (and thus why) they are played--passion, pressure, and emphasis is a great divider among pianists. Give me Wilhelm Kempff over an automaton any day, even with the occasional blundering of notes. I think this point is made rather beautifully in Isaac Stern's film "From Mao to Mozart". End tangent.
