Hi there,
I'm just a beginner of both Polyphone and soundfont in a month. I really like Polyphone, design of it and especially audition tone played by virtual keyboard is emulated more than Viena. As I have still many uncertainty things, I'd appreciate for a great advice.

-To lose file access (crashed?) : I still don't know the detail cause of this though, it sometime loses access to source sf2 file.
This happens often when play keyboard and adjusting parameters, again and again. Suddenly I notice no reflection to test sound by changing parameters. In such case, re-selecting other Instruments/Presets doesn't work, like the main window is frozen, and test sound also no move to other.
-It sometime happens without virtual keyboard opened.
-It could be back by re-opening the sf2 file, sometime.
Currently, I am always saving file even a single parameter change. If Polyphone is surviving, another parameter change gives Save icon activated.

Environments:
-600MB for GS (520MB PF) ... too big for one sf2 file?
-Win-7Pro SP1, x64, 8GB, Realtek/ASIO*
*In case of ASIO output, I have to terminate the polyphone process in Windows device manager, if the symptom happened. Otherwise he loses sound output.
-Polyphone 2.0.1 buff size : 1024 If the buff size is smaller, it gets to be unstable.
-Parameters of Instruments(in General) : 62465
-Parameters of Presets(in General) : 19839

Thanks and Cheers,

Hello Yarajii,

Welcome to the world of SoundFont creation!

Firstly, I'm going to attempt to describe what's happening:

1. You open a SoundFont's instrument/preset data and you change a value.
2. When you open the piano keyboard to test your changes, the change is not reflected in the sound.
3. After this intriguing thing happens, you go onto another instrument/preset, but the main part of the display does not change to the new instrument/preset, it stays on the old instrument/preset.
4. Thinking that there is something wrong, you save the SoundFont, but the changes are not reflected in the saved file.
5. After re-opening the SoundFont, the issue seems temporarily fixed, until it happens again.

I have been able to reproduce this bug/behaviour on Windows 10 Home, but I am not able to confirm because my Win10 machine's hard disk has died. I haven't tested it on my Ubuntu machine, but I will do so in the near future.

Thanks,

Strix.

Hello Strix,

Thanks for your welcome message and some info concern about OS dependency. I realized that Linux must be more stable, I should move on that way, maybe.
Your description was perfect, and appreciated you could understand the issue well. Indeed, I'm in trouble now, even without piano keyboard opened. Trying re-open the file, rebooting Polyphone, or edit other instruments without intention.
Although I reported a case of ASIO driver issue, it is used via ASIO4All. Because native ASIO (Roland) driver could not be recognized by Polyphone, but it is rerouting to Windows DirectSound. I guess Polyphone cannot kill process in Windows go through ASIO4All.

Thanks,

Hello Yarajii,

I have not been able to reproduce the issue on my Ubuntu Eoan Ermine (development branch) machine. I have tried to set as many parameters as I can but Polyphone remained responsive throughout the testing.

Guess it is an issue with Windows only.

Anyway, is reopening Polyphone no longer fixing the issue?

Thanks,

Strix.

Hello Strix,

I appreciate your deep kindness to care about me!!
The situation of Polyphone on Win-7 is also changed depend on a boot timing. Sometime stable in longer. It might have something collisions of other processes. I will continue to investigate on it, such as kill other audio process, screen saver, so on, because it is still not a commercial business right now, on the way of learning soundfont skills.
If a serious business would start, I will move on to Ubuntu what you are using. ;)

If I get a hint on this issue, I will post a message later days.

Thanks,

yarajii
