MIDI to WAV script Done here

Software
1

Hi!

I have made up a bash script that convert Music MIDI Files from a directory to WAV Audio files.

I don’t see a MIDI player in Haiku (the one I have bug after a playback) then I do it.

You must install before fluidsynth (software synthetiser)
You need also a SounFont file in sf2 format (here is Basic_GM_GS.sf2)
Then copy the script lines in a File with *.sh extention. And put it in your MIDI Files directory.
Then open a terminal and Run it with this command line
Exemple: sh convert.sh

That convert midi files to a Audio directory with new wav files.

Script file:

Soundfont=Basic_GM_GS.sf2
DestFold=Audio

echo "Convertisseur MIDI to WAV File"
NumMID=$(ls *.mid -1 | wc -l)
echo $NumMID

mkdir $DestFold
for file in *.mid
do
	echo "$file"
	inputFile=$file
	outFile=${inputFile%.mid}.wav
	fluidsynth -F $DestFold/$outFile  -i -n -T wav $Soundfont $inputFile
done

You can edit the Soundfont file source in the bash script file
For now the Soundfont must be placed in the MIDI Directory.

MIDI player is in the Haiku Application menu. You have to install some soundfonts first and select one in the media prefs however after installing the soundfonts.

I have one MIDI player in Haiku but every time I use it. The app crash after playing a File. The sound is OK but the MIDI player crash.

Did you reported it already?

No I don’t know the link for report a bug. But you had say you can choose your Soundfont file in it…I wonder if I have the same app as you. I will check it after my cours.

What is the name of your MIDI app?

bugreports at http://dev.haiku-os.org.

Thanks!

As i wrote it earlier: you can/have to pick a soundfont in the Media Preferences window.

This is the MIDI app I have in Haiku when I launch a MIDI File…I see nothing about Soundfont in it.
But here is the bug I always have with it when I Stop the sound or Quit the app.

VirtualBox_Haiku%20Beos_13_01_2020_21_44_42

Have find the Preference for MIDI in Haiku OS. But I can’t put new Soundfonts in the system (root access to the directory is denied).
If you have another Midi player you are welcome.

-Use HaikuDepot to install soundfonts or copy your soundfonts in the non-packaged folderstructure ( ~/config/non-packaged/data/synth/ )
-Use the Media preflet to select a soundfont
-Play midi files with MidiPlayer

For more info about reporting bugs check this guide: https://dev.haiku-os.org/wiki/ReportingBugs

Thanks for reply.
I view somes tickets already exist on the bug reports website about this App.

I will go try this(about Soundfont)

------------I Reply…again

I have tested the new Soundfont in non-package directory now after your reply and Midi Player app seem to no make error now. I don’t really understand why.

But I want to say Fluidsynth have a better quality for rendering midi file with the same Soundfont file. I don’t know what is it under the rendering of Midi Player.

I think MidiPlayer uses Fluidsynth also, so, not sure what the difference would be.

You can try Audacious player.
Audacious have fluidsynth based plugin for midi.

Try it. Play a midi file in MIDI Player with the same Soundfont than you use in fluidsynth command line (I heard a difference). example: Drum Kits absance in one of my test.
