probably race condition?

Offending MIDI file

none

Expected behavior

MIDI visualization began normally

Screenshots

the lwjgl.dll & OpenAL64.dll are extracted by this software automatically everytime press Start and placed next to the JAR file, yet still cannot find it. weird.

System
Provide your OS, and computer specs if applicable.

Tried other methods not working:

• Portable JAR file with Adoptium OpenJDK 11, same error
• Administrator Run the EXE file, same error
• Portable JAR file with Oracle JRE 8, incompatible! could not find main class
• Portable JAR file using latest Manjaro XFCE edtion Live CD as of 17 March 2022 (version 21.2.4) and straight install OpenJDK 11 without pacman -Syu, assertion error, forgot assertion

Question:

• does Gervill uses LWJGL's audio? I believe it's not. same with MIDI output devices. perhaps if we just disable LWJGL audio renderer for the 3D part might work?

I can make a build for you to try that has OpenAL disabled. Do you happen to have any other weird system audio configuration that might cause this?

Oh yes pls, we should see if this workaround works.

I happen to have had serveral virtual speaker devices like, virtual Surround sound device, VB (VoiceMeeter Banana) thingy, etc. Etc.

I already tried disabled all of those unused devices but the real device (Realtek) thingy, to no avail.

Here's a link to a .jar file that disables OpenAL when the program launches. Give it a try and report what happens!

Alright, let's see.. any MIDI, flourish, try both Gervill & MS GS wavetable.. Whoah!

It works.

And I can still hear the MIDI device sound both Gervill & MS GS wavetable of course. additionally to prove the working state, the kludge phone record this laptop playing will be provided later.

Oh and also, ignore the white space thingy, that's the DPI issue, I think either you or the JMonkeyEngine renderer forgot to take account with the DPI awareness. anyway..

Alright.

Well, this would be, the working workaround I guess. Disable the OpenAl, that's it. Really though, the OpenAl tends to be a problem with LWJGL here. And honestly it's a shame that we gotta turn it off if audio is not used if the case don't need so OR already had other audio module, etc. etc.

If one day we would like to have complementary *.wav e.g. to have singing audio alongside the MIDI, then we cannot use LWJGL's audio idk, must be external Media player Java module some sort. After all I believe it's going to be hard to manage LWJGL's audio to sync with the MIDI devices, right?

So yeah. Disable OpenAl makes it work.
