Sometimes, instead of a note or notes, a diagonal slash mark is printed on a staff. This is used for various purposes, such as strumming a chord (in a guitar part), or to mean that the previous beat should be repeated or that a note should be improvised. Mup does not support this directly, but you can simulate it.
It is most convenient to define a macro as follows for drawing a slash mark:
define SLASH(LOC) wide line (LOC.x - 2, LOC.y - 2) to (LOC.x + 2, LOC.y + 2) @
At any point where you want a slash instead of a note, use an
uncompressible space ("us"), and set a location tag on that chord
(not on the space itself).
Then call the macro with that tag.
For example:
1: 2g; 4f; [=h] us; SLASH(h) bar
If you often have entire measures of slash marks, another macro will
be useful. For example,
if you are in 4/4 or 2/2 time and would like a slash at each quarter
note, you could do this:
// Define a general macro to print a diagonal slash // relative to a location tag. define SLASH(LOC) wide line (LOC.x - 2, LOC.y - 2) to (LOC.x + 2, LOC.y + 2) @ // Define a macro that sets up 4 uncompressible spaces // with locations tags on each, // then prints a slash relative to each tag. define SLASHMEAS [=h] 4us; [=i]; [=j]; [=k]; SLASH(h) SLASH(i) SLASH(j) SLASH(k) @ // Now use the macro 1: SLASHMEAS bar
