ok here it is, darcy you provoked me to finally document this.

let me know if anything is missing...

fun fun.

philip aker had a beta version of a PI for feathered beams several years ago. i tried to reach him in november about developing a F07 version but haven't been able to get in contact with him.

have a look at the results here (tuplet assignment showing):

Any issues I should be aware of involving feathered beams over barlines?

poor you... they sometimes work and sometimes the positioning is weird. and will always require tweaking in the parts (can be used in linked parts of course).

Is there any way to get double feathered beams? i.e., a single beam group that starts out with no secondary beams, feathers out to three secondary beams, and feathers back in to one?

hm, maybe this would work: you will make 2 groups, with the beam broken between them. on the 32nd that ends the first make an invisible tuplet 1:0 32nds, then this and the 32nd that start the 2nd group should overlap exactly and the beams will be independent.

Can this be done over barlines?

probably with just as much difficulty. obviously you should always keep the two measures in the same system.

make one copy of every duration you need in the piece - it takes a long time to get it beautiful - and place it in a scratch staff or empty measure somewhere and don't delete the figure until you are finished your score. then just copy and transpose with only the feathered beam layer showing and adjust layer 1 rest positioning and stem direction (always down under feathered beams) as needed.

LAYERS AND OPTIONS

in layer 1:
- all notes that are not feathered, including placemarkers (NOT hidden) representing the values for each feathered beam
- rests frozen in default position
- glissando "arrival" notes

in layer 3
- feathered beams (layer 3 options set stems always up)
- rests hidden


ENTERING FEATHER NOTES AND TUPLETS

the example is for an 8th going to 64th (accel), you'll have to adjust settings given below accordingly if using 32nds, but the principle is the same (invert figures for decel)

for a feathered beam duration of an 8th note, enter 5 notes (32nds/64ths); dotted 8th duration = 7 notes; quarter duration = 9 notes.

starting at the end of the group, assign a series of 3:2 tuplets so that all but the last 3 and the 1st notes START a tuplet.

on the 1st note of the group, enter a tuplet 4n:m64ths (n = your base duration [32nd or 64th]; m = total duration in 64ths [use 64ths despite your base value])


ADJUST APPEARANCE

show layer 3 only:
- hide rests
- set flat beams
- hide ledger lines on all but 1st note of group
- set blank noteheads to all but 1st note of group
- change tuplets to not show number or shape (i've left them in to explain the examples)

using SECONDARY BEAM ANGLE TOOL, at 400% zoom, starting on the end of the beams, adjust the angle of the inner to outer beams to set the offset to -84, -56, -28 EVPUs; adjust the V positioning of each beam using left handle; start with the 16th beam and adjust by multiples of your document default beam separation, eg. 18, 36, 54.

using BEAM ANGLE TOOL, adjust the left and right handle offset according to your desires (values below are for when the pitch is on a line, add +12 EVPU to the left values if on a space). the first value is the best, because the various beams will straddle the staff lines in a more pleasing way.
- whole feathered beam symmetrical V/H: -56/42
- 16th beam horizontal: -30/30
- 8th beam horizontal: -15/0


MUSIC SPACING

show layer 1 only; apply music spacing.

show all layers.

adjust measure widths where necessary (2-click measure using measure tool instead of dragging)


VARIOUS

for tied notes in layer 1, make all but the initial note blank noteheads.

to make any adjustments for ugly collisions, reduce the m value in the first tuplet by x 64ths and insert an equivalent durational value in hidden rests at the end of the group).

for feathered glissandi, adjust as for collisions.

i find it best to have the feathered notes at 100%, since they are "normal" notes in this context. if you prefer them at a smaller percentage (eg. 75%), the heights of the beams will have to be adjusted accordingly, and you will have to adjust the horizontal positioning of the first note in the group manually.
