Fluidsynth 2.4.1 problem with The Nervous Filter.mid

[klerg]

FluidSynth version

2.4.1

Describe the bug

When the first 7 or so seconds of The Nervous Filter.mid is played in Fluidsynth 2.4.1 the audio drops out and sounds malformed and mangled

Expected behavior

Fluidsynth should not dropout in the 1st 7 or so second when playing The Nervous Filter.mid but sound like 2.4.0

Steps to reproduce

Open Fluidsynth 2.4.1. load a soundfont, play The Nervous Filter.mid, and you can hear it will dropout for the 1st 7 or so seconds so it sounds malformed and mangled

Additional context

I brought up this problem in #1430 before Fluidsynth 2.4.1 was released. I'm not sure was #1345 reverted in 2.4.1, or does this have to do with #1432, enabling NRPN 23 and 24, or something else, is any way to fix this issue ? Attached is The Nervous Filter.mid

There are no "dropouts" for me. This sounds like a problem with your soundcard. Pls. render it to an audio file instead:

fluidsynth -R 0 -C 0 -F "The Nervous Filter.ogg" "The Nervous Filter.mid" somesoundfont.sf2

If you hear dropouts, pls. upload the rendered file. If there are no dropouts, it's a problem on your system.

Ok so "dropouts" is not the right word. And it is more like clicks, cracks, and pops but it sounds better than 2.4.0, when I use this command it gives this error:

Rendering audio to file 'The Nervous Filter.ogg'..
fluidsynth: warning: Failed to determine audio file type from filename, defaulti
ng to WAV

But looks like it still works so I will upload it here, as the noise can clearly be heard in the 1st 7 seconds of The Nervous Filter.mid. I'm not sure if #1345 was reverted in 2.4.1 but overall it has less noise than 2.4.0.

I will upload The Nervous Filter.mid played with two soundfonts, 1mgm.sf2 and gm.sf2, in 2.4.0 and 2.4.1. Any way to get rid of the slow clicking and popping in the 1st 7 seconds of The Nervous Filter.mid in 2.4.1 ?

I'll see what can be done, but it'll take time. Also to reproduce this, can you pls. provide gm.sf2? I know 1mgm.sf2, I have it.

[derselbst]

Nevermind, I found it - it's GM_Roland.sf2

[klerg]

Sure that sounds good then, how long is that going to be ? Yes, gm.sf2 is the default gm.dls that comes with Windows converted to sf2 here is the link to get this file

Glad, you were able to find it. I noticed the 1st 7 seconds of The Nervous Filter.mid is less noisy with both 2GMGSMT.SF2 and 4GMGSMT.SF2 in 2.4.0 and 2.4.1. With 2.4.1 more noisy than 2.4.0 so here are the renderings, does this help at all ?
