I know there's been previous endless discussion, but... While I'm sure it won't satisfy EVERYONE, I think it will be better than nothing to have some option for MIDI output to simulate a strum pattern. I don't know any Scheme, and I don't play a chorded instrument, so it's beyond me, but the relationship between chord names and fretboard diagrams suggests that it would be possible to use that information to automatically construct something like:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % See https://linuxmusicians.com/viewtopic.php?t=23660 % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \version "2.22.1" \language "english" melody = \relative c' { \time 4/4 \key c \major \tempo 4=80 % Guitar strum (Spanish guitar strum?) \clef "treble_8" % E major chord \appoggiatura { e,,32~ [ <e~ b'~>32 <e~ b'~ e~>32 <e~ b'~ e~ gs~>32 <e~ b'~ e~ gs~ b~>32 ] } <e b' e gs b e>2 } \score { \new Staff \melody \midi { } } %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% To my very untrained ear, when the above is played, it sounds "close enough" to a generic guitar strum. Again, it wouldn't be perfect, and there are probably a million and one exceptions, variations, etc. Is it a downstroke? Is it an upstroke? Bla-bla-blah. The folks who are that fussy and have need of such precision wouldn't be forced to use the option. But right now, there's nothing other than constructing it by hand each time, for every chord. I think something would be better than nothing.
