tremolator

tremolator is a patch to tremolo tool from craigsapp/humlib, that adds *tremolo/*Xtremolo interpretations to each tremolo note encoded with @n@ markers.

humlib tools are not required to use tremolator, since tremolo and tabber from humlib are also implemented as filters in Verovio Humdrum Viewer.

usage

tremolator [file].krn

in combination with humlib tools:

tremolator [file].krn | tremolo

or (for more complicated files with spine splits and merges):

tabber [file].krn | tremolator | tremolo | tabber -r

examples

the most simple one:

input (test1.krn):

**kern
1c@8@
=
8cL
8c
8c
8cJ
8cL
8c
8c
8cJ
=
1c@8@
==
*-

command:

tremolator test1.krn | tremolo

output:

**kern
*tremolo
8cL
8c
8c
