nuancing and customizing midi rendering

[Bric]

Please forgive me if this has been discussed and/or documented; I 
haven't found specifics yet.

Are there lilypond controls for things like staccato, accents, and other 
articulations/dynamics, with respect to midi output?

I noticed that the midi output is sensitive to the "\staccato" 
directive, for instance, trying alter the sound accordingly.

But can one finesse the \staccato, controlling the exact length of the 
note, in milliseconds or whatever the midi resolution allows?

also, any other similar ornamentations, and articulations one could 
control and customize in lily code ?  I realize the piano, forte, 
fortissimo, etc., are honored, and there is a minimum and maximum 
midivolume directive, which apparently would factor into crescendo's and 
diminuendo's... How/where do i find out more ?

thanks
