+ ++Mup supports up to three voices per staff. If you need more than that, such as +when 4 notes of different lengths occur on the same beat, it is possible +to position extra notes manually. +Manually positioned notes will not be included in +MIDI output. +
+
+First of all, unless the fourth voice is vertically far away from the other two,
+you'll probably need to reserve some
+extra space to the left or right of the other chords. This can be done
+by adding a bit of
+padding to the chord.
+If you want the extra note on the left of the regular
+voices, add padding to whichever regular voice is leftmost. If you want it
+on the right, the padding will have to go on the following note, or on
+the bar line if you are on the last chord of a measure. The amount of
+padding to add may have to be determined by trial and error; 5 stepsizes
+is a good first guess. Next, set a
+location tag
+on one of the notes
+in one of the regular groups.
+The manually-positioned note will be placed relative to
+that location tag. The x will be slightly left or right of the
+west or east of the existing group; something like 3 stepsizes might be
+a good first guess. The y can be specified in terms of
+stepsizes up from the note you used for the location tag. You can use a
+print statement
+using one of the special
+music characters,
+such as:
+dblwhole, 1n, up2n, dn2n, up4n, up32n, etc. If the note needs ledger lines,
+dots, or accidentals, these too have to be manually positioned,
+which can be a bit tricky. Here is a simple example:
+
+score +vscheme=3o +beamstyle=4,4,4,4 + +music +1 1: [pad 4] 4g =h; a; b; a; +1 2: 4.c;8;2; +1 3: [down] 8e;; [ho 0] 2.f; +print (h.w - 2.3, h.y + 3) "\(up2n)" +bar +
+If you also need to place an accidental and/or dots, more padding should be
+requested, and additional print statements used for each item. For example,
+you could specify perhaps 5 stepsizes of padding, then add:
+
+print (h.w - 5, h.y + 3) "\(flat)" +
+Ledger lines needed by the notes also have to be +placed manually, using the "line" +command. If the note is more than three steps above or below the staff, more +than one ledger line would be needed, and each would need to be specified +separately. The y coordinate of the each ledger line would be the same +as the y coordinate of the note, +plus or minus some number of step sizes. The length of +the line depends on the note head. About 4.5 stepsizes is a good estimate for +most notes, but a double whole needs more like 6 stepsizes. +
