Comment (by kakuhen):

 OK I have attempting building all three softwares **using fluidsynth
 2.2.8**, here is the summary.

 **denemo**:
 - Environment: Mac OS X 10.5.17 (x86_64) with Xcode 12.4 (12D4e)
 - MacPorts Context: Compiling in trace mode, allowing binary archives
 - Build succeeds and binary seemed functional when testing. **The software
 is compatible with fluidsynth 2.2.8.**

 **lmms**
 - Environment: Mac OS X 10.5.17 (x86_64) with Xcode 12.4 (12D4e)
 - MacPorts Context: Compiling in trace mode, allowing binary archives
 - Build fails, but not due to fluidsynth. We are encountering the defect
 described in #58009. **The software is likely compatible with fluidsynth
 2.2.8.**

 **gstreamer1-gst-plugins-bad**
 - Environment: Mac OS X 10.5.17 (x86_64) with Xcode 12.4 (12D4e)
 - MacPorts Context: Compiling in trace mode, allowing binary archives
 - Build succeeds. **The software is compatible with fluidsynth 2.2.8.**

 If you would like more details on this process, please refer to the Org
 Mode document I will attach to this ticket. It includes problems I
 encountered when e.g. building dependents of these ports strictly from
 source. It also includes snippets of relevant logs to demonstrate programs
 functioning correctly (or where builds failed).
