Summary

This issue stems from some type of failure during the AU plugin's validation on a MacOS system. It likely has something to do with information such as the manufacturer string or code not being correctly formatted.

Summary

At times, the notes hang indefinitely after releasing a note. It doesn't consistently do this across patches or even sometimes across notes played within the same patch.

System Info

Windows / MacOS

Notes

The behavior occurs when both the envelope generator's (EG) sustain parameter is set lower (lower = more intense hanging, i.e. -60dB is the worst while 0.0dB has no hanging) and the user plays a quick note. This helps to narrow down the cause of this issue because I suspect that playing quick notes results in some funkiness being caused in the renderNextBlock(...) method. While still not entirely clear, this is a good starting point.

If the sustain is set to -60.0dB, so long as the user releases the note before the decay duration is over then it will repeat whatever value is there indefinitely. If the user holds the note for long enough, the EG acts as normal. If the sustain is set to 0.0dB, there are no problems with this.

Hi,

I am currently trying to build your project on Fedora Linux using :

• gcc-x86_64-redhat_linux
• clang-15.0.7-x86_64-redhat-linux-gnu
• VSCodium

I had to add to CMakeLists.txt:

set(CMAKE_CXX_STANDARD 20)
add_compile_definitions(JUCE_MODAL_LOOPS_PERMITTED)

And in some source files to replace:
log10f,atanf,tanhf,..
with
log10,atan,tanh,...

But the compilation fails in the end with this error message:

/usr/bin/ld: libPhantomData.a(BinaryData1.cpp.o): relocation R_X86_64_32S against symbol _ZN11PhantomData17originalFilenamesE' can not be used when making a shared object; recompile with -fPIC [build] /usr/bin/ld: failed to set dynamic section sizes: bad value

The -fPIC option seems to be already passed to the compiler.

Any idea to solve this?
