multimeasure rests

[nagymusic]

What indicator has replaced use_multimeasure_rests=True in the updated version of rmakers?

stack = rmakers.stack(
  rmakers.note(),
  rmakers.force_rest(abjad.select().leaves().get([1, -1])),
  #use_multimeasure_rests=True,
  )

Thanks!

Hey Zvony (@nagymusic), I kinda demoted multimeasure rests in the updated rmakers, largely because my own use of multimeasure rests always seemed to be in the creation of duration-multiplied mm rests. So there's a new rmakers.multipied_duration() factory function that can take abjad.MultimeasureRest as its first argument and produce multimeasure rests with a duration multipliers.

The rmakers.mutliplied_duration() function is implemented in the makers.py module. The function is just a wrapper around the rmakers.MultipliedDurationRhythmMaker class (also implemented in makers.py). So take a look at the rmakers.MultipiledDurationRhythmMaker docstring. There's an example showing multimeasure rest creation. See if maybe that will get you what you want.

The usage is super simple and looks like this:

            >>> rhythm_maker = rmakers.multiplied_duration(
            ...     abjad.MultimeasureRest
            ... )
            >>> divisions = [(1, 4), (3, 16), (5, 8), (1, 3)]
            >>> selections = rhythm_maker(divisions)

Thanks, Trevor. This makes sense. I just have a quick follow up question.

Is it possible to wrap rmakers.multipled_duration(abjad.MultimeasureRest) in the stack so that it automatically generates whole measure rests for the silenced divisions. I tried something like that in the example below. I love the updated rmakers - thank you once again!

stack = rmakers.stack(
    rmakers.note(),
    rmakers.force_rest(
        abjad.select().logical_ties().get([0], 2)[1:-1],
    ),
    rmakers.multiplied_duration(abjad.MultimeasureRest(?))
)

divisions = [(4, 8), (3, 8), (4, 8), (3, 8), (2, 8)]

selection = stack(divisions)
lilypond_file = abjad.LilyPondFile.rhythm(
    selection, divisions
)

Hey Zvony I guess it's not possible to selectively replace ("force" in the language of the updated package) in the way you're looking for.

That'll be really easy for me to add into the package in a bit. For now you can postprocess the output of your stack: use selectors to select the components you want to replace with multimeasure rests; then use abjad.mutate().replace().

Hey Trevor,
I see. The use_multimeasure_rests=True was a time saver in the earlier version of rmakers when I used it in a few instances, mainly with incised and/or silenced divisions. Thank you for considering to add it into the package.

As you suggested, I'm trying to replace the output of my stack by replacing the middle (third) measure in 4/8 with a new whole-measure rest measure using rmakers.multiplied_duration(abjad.MultimeasureRest()) and abjad.mutate().replace(). But it doesn't seem to be working. Any ideas?

Thank you!
Zvony

import abjad
from abjadext import rmakers

stack = rmakers.stack(
    rmakers.note(),
    rmakers.force_rest(
        abjad.select().logical_ties().get([0], 2)[1:-1],
    ),
)

divisions = [(4, 8), (3, 8), (4, 8), (3, 8), (2, 8)]
selection = stack(divisions)

######################

multimeasure_rests = rmakers.multiplied_duration(abjad.MultimeasureRest)

new_divisions = [(4, 8)]
new_selections = multimeasure_rests(new_divisions)

select_measures = abjad.select(selection).group_by_measure()
abjad.mutate(select_measures[2:3]).replace(new_selections)

lilypond_file = abjad.LilyPondFile.rhythm(
    selection, divisions
)

abjad.show(lilypond_file)

Trevor,
I had a chance to work on the application of selected multi-measure rests within rmakers. Per your suggestion, I also reviewed the rmakers.mutliplied_duration() function as it is implemented in the makers.py module.

I understand if you may not be able to answer this, but is it possible to apply the same (or similar) variables to rmakers.multiplied_duration(abjad.MultimeasureRest) like it's done to rmakers.force_rest() below? I ask this because in this way one may be able to apply the same selections of measures tomultiplied_duration as it is currently used with force_rests.

stack = rmakers.stack(
    rmakers.accelerando(
        [(1, 8), (1, 20), (1, 16)],
        ),
    rmakers.force_rest(abjad.select().tuplets().get([1], 2)),
    #rmakers.multiplied_duration(abjad.MultimeasureRest), => (abjad.select().tuplets().get([1], 2))?
    rmakers.rewrite_rest_filled(),
    rmakers.feather_beam(beam_rests=True, stemlet_length=0.75,),
    rmakers.duration_bracket(),
    rmakers.extract_trivial(),
    )

divisions = [(4, 8), (3, 8), (4, 8), (3, 8)]
selection = stack(divisions)

lilypond_file = abjad.LilyPondFile.rhythm(selection, divisions)
abjad.show(lilypond_file)

Many thanks,
Zvony

Hi Zvony, Your current output looks like this: [image: zvony.png] What do you want to output instead? Multimeasure rests (instead of vanilla rests) in measures 2 and 4? Trevor.

Thanks, Trevor. That's correct - Multimeasure rests instead of vanilla
rests in measures 2 and 4.

[trevorbaca]

Hi Zvony, Alas, there's no corresponding method for forcing notes / rest to multimeasure rests in the rmakers package. Do it "by hand" after you've made your selection with stack: loop, look for the rests in question, make a multimeasure rest equal in duration, and replace. Trevor.
