No idea, but to fix the bug someone would need to debug the issue. Honestly speaking, fixing 32-bit specific issues is *mostly* a waste of time today.

You should definitely upgrade as soon as possible. There is absolutely zero advantage to running 32-bit only.

It would probably help if anyone else could comment on experiencing this bug in the 32-bit version.

If it isn't often reported it could be something very system-specific. In which case you should try loading Reaper configured with absolutely no other plug-ins. Put OBXD in a different folder like OBXD/obxd.dll on your desktop and add this to Reaper's plug-in path while erasing the other plug-in path entries.

Load only OBXD and try to reproduce the bug with a single instance in an empty project.

Testing 32-bit vs. 64-bit would also be very useful and if you can't do that, someone else will need to.

Why are they still changing it? I thought it was already finished and "perfect" a long time ago...

"The myth of bug-free software: There is no such thing as bug-free software."

... but, that said, it's very difficult to even determine whether this is a bug, or just another plug-in the user is running which shit all over OBXD's memory. (In 32-bit the memory space is smaller. Another plug-in can far more easily corrupt some memory.)

It is interesting that the number of voices has an effect but not at all conclusive.

Identifying the cause of such issues and actually fixing them is an extremely labor-intensive process that requires a dedicated developer to maintain the software.

Reaper seems to be working in Linux only with Wine, so I think about something else for that, and try to test it soon.

Edit: When using JACK, and OBXd goes mute, there appears an error message in terminal:

Code: Select all

JackEngine::XRun: client = renoise was not finished, state = Running
JackAudioDriver::ProcessGraphAsyncMaster: Process error
But the problem is same also when using ALSA, so it's not about JACK.

There is also a native Linux version of Reaper available if you search for it. It is still being worked on.

I use Linux for other things, and I really, really like it, but not for audio. :wink:

Not when I also have a Windows system that runs DAWs and plugins with ease. When I want to make sounds, I do not want to get into tweaking and troubleshooting the PC mode if that can be avoided. :help:

OB-Xd 1.4 runs really, really, well on a Windows x64 system for me. :clap:

Unfortunately the error message doesn't tell you anything useful. So you'll probably need to run the debug version of JACK or ALSA to get a more detailed error message.

It could be many different things, possibly an exception was triggered while processing. It might also be triggering an exception because a NAN was detected in the output buffer.

Better error messages would be very useful!

Example:
"JackAudioDriver: Exception #nnn 'exception name' encountered while processing audio callback."
"JackAudioDriver: Exception #nnn 'floating point exception: NAN' while transforming output buffer."

You'll probably want to post on a Linux audio forum and ask if other users can test the plug-in to reproduce this issue. You might get lucky and also find someone able to debug it.

I just tested it in Ardour. Not working properly in there either.

Good idea. Thanks for help.

I have added a small install script for Linux. Please let me know how useful it is :)

Hello George !

Would it be a big work to try to add a feature which shows in tooltip the changing value of a knob while is is turned by the mouse?

Or perhaps a feature showing its value when it is hovered by the mouse as it is done in Dexed (or by a tooltip, any method which would be the most simple to implement).

It's just a suggestion.


Good Sunday to everybody!

Yes, it could be implemented but I'd need some funds for that :)

How could this be arranged in practice? Donate button, crowdfunding, can it be commercialised? Obxd is an amazing poly emulation soundwise, and it's awesome you maintain it, but there's some room for usability improvements. I'd be happy to chip in to see some development on these kinds of small things:

- MIDI CC configuration saved across sessions
- notched knob control on transpose (semitones)
- tempo sync option on modulation speed
- individual modulation amounts on the assignable parameters
- maybe less screen estate allocated for per-voice panning controls

Wasn't this the no-no that got Soshi Studio into trouble a couple of years ago ?
