+time signatures, few or no bar lines, few or no ties, slurs or
+phrasemarks, ornaments implied by the structure of the music, or
+indicated by, e.g., one or more thick lines through the stem of a note
+(Purcell and Farnaby both use this extensively, but with rather
+different meanings). For Dowland's music it may also mean being able

it's some sort of a numerical (truncation/roundoff) problem.

-. * Chords:
-. * Bass/inversion pitch when not part of Chord
-Sometimes a series of changing chords will be blocked out over a static tone
-in the bass, usually this was referred to as a pedal tone (and it's been
-continued to be used, even in contemporary music). Another less frequently
-used practice is putting a non-chordal tone in the bass (that is not acting
-as a pedal tone) in order to create tension or make a more colorful sound.
-There are examples of this in the classsical literature, but its use is much
-more prevalent today. For example, the chord sequence Dm7 - Dm7/G is such a
-sequence, and the Dm7/G defies easy classification. Is it a G7(no 3rd)add
-9/11? Or is it a G7(no 3rd)add2/4? Or perhaps Dm7 add11? It's a heck of a
-lot easier to read to just leave it as Dm7/G!
-. * Diminished does not mean 5-
-When speaking of a chord, dimished can mean one of two things: A diminished
-triad or a dimished seventh chord (which is distinctly different from what's
-known as the 'half-diminished' chord). The triad is a root with a flat
-third and flat fifth, and is notated (at least in America, someone else will
-have to fill me in on other countries) as (using C as the root) Cdim, or Co.
-The diminished seventh has a root with a flat third, flat fifth, and a
-doubly flatted seventh (which is enharmonically equivalent to a sixth, and
-from which comes tons of confusion). It is usually notated as (again, using
-C as the root) Cdim7 or Co7.

-> Would it be hard to add support for proper dynamics in MIDI output? I
-> would really like to have this feature...
-
-Concretely spoken, for dynamics you have to write a performer
-(Dynamics_performer), that will take the input requests. If I
-understand correctly, every MIDI note played must have its dynamic
-strength set separately. That means the the Dynamics_performer must
-set the strength of every Audio_note it finds. This means that one
-has to modify existing Audio items. The best way of doing this is
-with a broadcast/acknowledge process.
-
-So the best way of handling this, is
-
- 1 supporting dynamic settings in Audio_note
-
- 2 Write a Dynamics_performer that will modify
- any notes it finds to set appropriate strengths.
-
-I'd say that the work involved is not hard, but you have to be fluent
-with C++ and need some insight into the working of Notation Contexts
-and friends. I guess I could do it in a day or so, but if you are not
-so fluent with the inner workings of LilyPond, it could take you some
-more time (A few more days?).
-
-Please note, that I am *not* going to code this myself: my days are
-valuable, and I think I have more interesting things to do than fixing
-the MIDI output (I don't even have a soundcard). But I *do* want to help
-you or other people with implementing this, so if you need help, don't
-hesitate to ask.
