Instrument gate times? What is the theory?
Piano (including different kinds of pianos) and flute are configured to sound notes at 95% (length) of what is written; other than some drums where I can't imagine it makes much difference, no other instruments (in 3.0) have this property configured. While this makes legato and tenuto work credibly, for these two and no other instruments, I don't understand why these two instruments are unique among the universe of instruments defined in instruments.xml. I'd hate to see it changed, because it would break the sound of every carefully-tweaked score in existence. But I don't understand the theory; perhaps this is just a historical artifact?
I discovered this working with a score retrieved from .com, where all the notes had 95% phrasing, but the instrument didn't seem to be piano -- in fact, the person who created it started with piano, and changed the sound via the mixer. The original piano's 95% remained! This is a very non-obvious situation for the person who really cares about phrasing.
It sure would be wonderful if end/gate time was available in the inspector, and thus settable over a range of selected notes, as with all inspector-visible properties. The new PianoRoll Ed. is really great, but still not enough.
