+As MIDI files do not contain any actual audio data, changes in these
+context properties translate only to requests for changing MIDI channel
+controls in the outputted MIDI files. Whether a particular MIDI device
+(such as a software MIDI player) can actually handle any of these
+requests in a MIDI file is entirely up to the implementation of the
+device: a device may choose to ignore some or all of these requests.
+Also, how a MIDI device will interpret different values for these
+controls (generally, the MIDI standard fixes the behavior only at the
+endpoints of the value range available for each control), and whether a
+change in the value of a control will affect notes already playing on
+that MIDI channel or not, is also specific to the MIDI device
+implementation.
+
+When generating MIDI files, LilyPond will simply transform the
+fractional values within each range linearly into values in a
+corresponding (7-bit, or 14-bit for MIDI channel controls which support
+fine resolution) integer range (0-127 or 0-32767, respectively),
+rounding fractional values towards the nearest integer away from zero.
+The converted integer values are stored as-is in the generated MIDI
+file. Please consult the documentation of your MIDI device for
+information about how the device interprets these values.
