--a poetry sequencer for crow, just friends, and w/tape
--input 1: clock
--outputs 1 & 3: v/8
--outputs 2 & 4: AR envelopes
--begin by giving your poem a title in druid using the title function (i.e., typing title followed by your title in quotes), like so:
--title "Christabel"
--this will start the clocks running and create an initial sequence
--continue by updating the sequence in druid by typing text followed by a new line of poetry in quotes — e.g.,
--text "'Tis the middle of night by the castle clock,"
--note: it's probably best to reset crow after using this script and before using another one or using this one again. Not doing so can lead to crashes
