Midi mapping issue when using FluidSynth 2.4.4

[raffaele-morelli]

Opening the software after some time (after donation :-) ) the midi mapping seems to be completely gone

In the image above, none of the selected sounds like a drum, eg. the Std Kit 1 & 2 are mapped to piano, Room kit seemss a glockenspiel etc...

First click bar is played by a string (seems a double bass)

If I send other midi messages some change takes place but the incorrect mapping is still there

Here follows some sys info:
Debian testing(6.12.20-rt-amd64 #1 SMP PREEMPT_RT Debian 6.12.20-1 (2025-03-23) x86_64 GNU/Linux)
jjazzlab 4.1.2-1
fluid-soundfont-gm 3.1-5.3
fluidr3mono-gm-soundfont 2.315-7
fluidsynth 2.4.4+dfsg-1

You should use the embedded FluidSynth, all these problems would be gone. If you don't want to use FluidSynth, you need to read this https://jjazzlab.gitbook.io/user-guide/sounds/other-synths

[raffaele-morelli]

But I am currently using the embedded FluidSynth, that's the problem...

[jjazzboss]

ok, so I need steps how to reproduce. Can you send me the .sng + .mix file you use ? I also need the log file https://jjazzlab.gitbook.io/user-guide/faq#how-to-submit-a-bug-how-to-find-the-log-file

[jjazzboss]

Also, when using the embedded FluidSynth, do NOT use the "Send GM/XG/... midi messages" commands from the mix console menu, this can misconfigure FluidSynth. In the next release I'll make those commands disabled in that case.

[raffaele-morelli]

This happens with each and every song with and without sending mide messages of any kind.
BTW attached mix files, song is "Afro blue" (default)

JazzWaltzSlow.S423.zip

PS this morning I've cleaned ./jjazzlab dir, purged the package, problem still persists.

Log is fine. I think it might be due to the fluidsynth version you use (2.4.4). It looks like FluidSynth does not react anymore to program changes sent by JJazzLab.

JJazzLab was tested with FluidSynth 2.2.

I checked the Fluidsynth changes in https://github.com/FluidSynth/fluidsynth/releases and I spotted 2 possible impacting changes:
FluidSynth/fluidsynth#1307 in 2.3.5
FluidSynth/fluidsynth#1382 in 2.4.0

I develop on windows, so please could you try again with different FluidSynth versions ? E.g. 2.3.4 then 2.3.5. If it works, try 2.3.7 then 2.4.0. Thanks

[raffaele-morelli]

You're right, downgrading both fluidsynth and libfluidsynth3 did it

Every release < 2.4.4 works fine

Which on debian and derivatives means packages
fluidsynth_2.3.5-1_amd64.deb
fluidsynth_2.3.6-1_amd64.deb
fluidsynth_2.4.0-1_amd64.deb
fluidsynth_2.4.2-1_amd64.deb
fluidsynth_2.4.3-1_amd64.deb

and libfluidsynth3 accordingly => https://snapshot.debian.org/binary/libfluidsynth3/

Anyway, donate window is back again after installing 2.4.3 (gone away with the code I had)

[stanislas-henrard]

Hello, I have the same exact problem on macOS and don't know how to install an older version of fluidsynth. Do you happen to know how to do it ?

Thank you 🙏

[jjazzboss]

@stanislas-henrard no. Check homebrew doc ?

[jjazzboss]

I found this: FluidSynth/fluidsynth#1514

So it seems to be a bug in 2.4.4, which will be fixed in next release (2.4.5?). When 2.4.5 is out, it would help if one of you guys could test it again. In the meantime I'll update the online doc to avoid 2.4.4.

[stanislas-henrard]

Homebrew doesn't allow installing previous version unfortunately. I will wait for their next version and test again, thanks !
