Thanks Farox, it works!

I'm now only on hosted cause a dead gfx card on my old PC.
Anyway i have added an Assign for Timidity on Startup-Sequence and i have a working Midi player.
Also asking A.I. to fix the problem after 3 attempt it fixed it...using FindTask() and RemTask().
Attached is the program and the source.
Test and report in case don't work.

If you are using AROS One, you should not see this message.
WidiMidi uses software to play music, and the instruments are located in the Timidity folder, which on AROS One is located at SYS:Extras/Music/Timidity

Se stai utilizzando AROS One non dovresti avere questo messaggio.
WidiMidi utilizza il software per suonare e gli strumenti si trovano appunto nella cartella Timidity che su AROS One e assegnata al percorso SYS:Extras/Music/Timidity

I'm on Aros hosted and when i try to play a midi file it say "Please Insert volume Timidity in any drive" . Do i need to install Timidity ?

Okay, I’m attaching the source code here. In the archive, I’ve included the WildMui-Gui source code, the WildMidi.cfg file, the MildMidi 4.06 64-bit executable, the MildMui-Gui executable, and a file for permanent Italian localization (there are 4 available languages; for the other languages, you just need to modify the script)

Important: WildMidi.cfg must be located in the WildMui-Gui directory; otherwise, it won’t play. You can copy MildMidi 4.06 wherever you want, but if you copy it to the GUI folder, it will be easier to find.

Ok, allego qui il sorgente, nell'archivio allego il sorgente di WildMui-Gui, file WildMidi.cfg, l'eseguibile di MildMidi 4.06 64bit, l'eseguibile MildMui-Gui e un file per la localizzazione in italiano permanente (le lingue disponibili sono 4, le altre lingua basta motificare lo script)

Importante WildMidi.cfg deve trovarsi nel percorso WildMui-Gui altrimenti non suona, mentre MildMidi 4.06 puoi copiarlo dove vuoi, se lo copi nella cartella della GUI è più facile il ritrovamento.

I could take a look, if you did not find someone.

Posso darci un'occhiata io se nel frattempo non hai trovato nessun altro.

I've compiled the latest version of WildMidi 0.4.6 for both 32-bit and 64-bit v11, available on the Aros Archive.
Over the past few days, I’ve been trying to create a GUI for WildMidi 0.4.6 using I.A. (see screenshot). The GUI is multilingual and works well, but I haven’t been able to get the Pause and Stop tabs to work—this is because WildMidi uses the P (Play/Pause) and Q (Quit) keys.

The Play tab works fine, but the only way to stop the music is through Scout. I.A. tried to use the same tools as Scout, but we weren’t able to resolve the issue.

If anyone is interested in giving it a try, I can attach the C source code for the GUI.
