Unable to load DLS files in fluidsynth 2.3.4 Windows builds. #1298

Closed RoqueDeicide closed 6 months ago

RoqueDeicide commented 6 months ago

FluidSynth version

2.3.4

Describe the bug

DLS files don't load. "error: Not a Soundfont file" is printed out when attempting to load one from the shell. "Parameter 'RLNDGM.DLS' not a SoundFont or MIDI file or error occurred identifying it." message is printed out when attempting to load one from the command line.

Expected behavior

DLS files should be able to load.

Steps to reproduce

Attempt to load any DLS file from any Windows build from 2.3.4 release page.

Additional context

Tried to load gm.dls and RLNDGM.DLS with the same result. libinstpatch-2.dll is present in all 2.3.4 Windows builds, but it doesn't appear to be loaded by fluidsynth.exe. Logs for fluidsynth compilation for Release 34 in Azure indicate "Support for DLS files: no (libinstpatch not found)".

Thanks for the report. Support for DLS and SF3 in the precompiled binaries seems to have gone lost in 2.3.2. The PR linked above should fix the issue. Feel free to grab the fluidsynth-x64 artifact from here and let me know whether it works for you: https://dev.azure.com/tommbrt/tommbrt/_build/results?buildId=9829&view=artifacts&pathAsName=false&type=publishedArtifacts

Thank you. I downloaded fluidsynth-x64, and it appears to load DLS files successfully, but, oddly enough, it now prints "error: Not a Soundfont file" regardless of how I load the DLS file. Whatever, it works, as far as I am concerned.

Thanks for confirming. That error is fine - it just tries the SF2 loader before it attempts the DLS loader.
