Hi,
Until now, I use WMP to play the midi compiled in lilypond. I have
coolsoft
virtualmidisynth installed with a sf2 of my taste and no problem,
everything works fine.
The problem: WMP blocks the midi file while (and after) it's playing,
so if
I modify something in lilypond and I want to hear it, I have to close
WMP,
then compile, go to the folder and reproduce again.. and I'm composing
so I
do it a LOT of times.
Question: anybody knows a mid player with does not block the file, so
it
loads the file each time for playing it?
I ran into the same issue as you and found the easiest option was to
simply force Windows to kill any open WMP instances within my build
script so I would not have to remember to manually close it first.
Below is what I use with Visual Studio Code as my IDE of choice and
Lilypond running within WSL. The main part you'll be interested in is
right near the beginning of build.sh.

#!/usr/bin/env bash
close_wmplayer=1
format=pdf
crop=0
function build {
# NOTE: Windows Media Player locks files it has opened.
# This prevents LilyPond from generating a new MIDI file.
# The workaround is to forcefully close all instances of
# the player to ensure the build process works reliably.
if (( $close_wmplayer == 1)); then
taskkill //im wmplayer.exe 2>/dev/null
close_wmplayer=0
