Selecting files in browser does not open anything in reaper for linux

[vssasks]

Selecting files in browser does not open anything in reaper for linux. Inscription None remains near the folder button. Nothing is loaded.

You must add a track and load fluida there. Duno why file loading didn't work on the master bus.

[vssasks]

Of course i insert lv2 into a track or item. The result is the same i.e. sf2 is not loaded into lv2. I have 64-bit reaper and 64-bit fluida.lv2 of course self-compiled. Your binary refused to load alltogether.

[brummer10]

Strange, here it is as it works for me:

[vssasks]

Your screenshot does not show that sf2 is loaded. It shows none.

[vssasks]

What's your version of reaper btw? I have noticed that vss3 vst is loaded in one version and works well but in later versions it selfresets to default all the time

[brummer10]

@vssasks it is a gif, don't you see the animation? It's a old 6+21-dev version.

[brummer10]

Here is a shot from the gif showing what you want to see

[vssasks]

Does not work for me on 6.31 and 6.47

[brummer10]

Just checked out v6.71, still works here as expected. Do you use latest checkout from fluida git? Which distribution do you use? I'm on debian/sid by the way.

Also, you may checkout what happen when you save a preset, for example with jalv, with a soundfont loaded. Then load this preset when you use reaper. Did that work?

[vssasks]

I use devuan beowulf based on sysvinit. I used last checkout - i recompiled after issuing 'git checkout' command. I don't have jalv as I use only alsa for audio. Maybe you can save a preset for me? To /home dir fluid gm as I also have it

[brummer10]

Do you've Ardour? That will as well work for save a preset. And, in Ardour you could load the sound-font via drag n' drop.

[vssasks]

I don't have ardour either

[vssasks]

Perhaps you can rewrite the code to support classical folder browsing or smth like that?

[vssasks]

Or change code to compile with static libs and provide static binary?

[brummer10]

From Fluida, it is all supported. Look how ardour shows fluida with internal controls:

As you could see there is a file browser button, this one is from Ardour. It's simply that reaper didn't support that feature, so there is no way for me to use any internal file browser from reaper to fetch a file. On top of that, reaper didn't forward d n' d events to the plugin, so file loading by d n' d isn't possible neither. The plugin use just libcairo, libX11 and libfluidsynth. Non of them been suited to compile statically as they are linked with glibc. The resulting binary will be huge, very, very huge.

[vssasks]

Thanks for explanations. I will contact reaper developers and let them know about this problem. V6.71 exibits same problem + more cpu consuming than 6.30. Whatever they say each new version is more hungry for cpu.

Try file selector like in gunshot convolution reverb. It works

[Audiojunkie]

I’m interested in this too, but don’t understand what you mean. 🙂

[brummer10]

Try file selector like in gunshot convolution reverb. It works

You know that's a VST plugin. VST does direct UI->dsp communication while LV2 communicate like this UI ->host -> dsp -> host -> UI.

[brummer10]

@vssasks To find out why this file selector didn't work for you in reaper, you may try this one: https://github.com/brummer10/XFileSelect That's the file selector I use in Fluida. build it and run it from terminal, select a file and press "load". Check if the filename is outputted in terminal. If that doesn't work, I could implement some debugging output to find out were it is broken.

[vssasks]

After clicking on selected file xfileselect just disapeared and terminal says: FILE: ~/fluid.sf2

[vssasks]

By disappeared I mean self-terminated is that normal?

[brummer10]

Yes, that is the expected behave. So it means that the file browser works and forward the filename to the UI. Now, next question will be if the UI is able to forward the name to the engine. When you go to the Fluida source directory and open the file /Fluida/fluida.cpp with a text editor, go to line 592 soundfont = (const char*)(file_path+1); and put a new line below that one were you put fprintf(stderr, "DSP -> %s\n", soundfont.c_str()); save, rebuild and install, then start reaper from terminal, try to load a soundfont with fluida. Now, when the message makes it from the UI to the engine there should be a output in terminal like this: DSP -> /usr/share/sounds/sf2/FluidR3_GM.sf2 If so, then this part even works. Check at this point if you get sound when you play a key on the integrated keyboard. If no output appears it means that for some reason the atom communication from UI to dsp is broken.

[vssasks]

Such mesage is absent. It only shows Alsa: using mmap interleaved

[brummer10]

I didn't understand the answer, that's the message you get after you've edited, build and install the source files, or you get it independent of that? Just a side step, which lv2-dev version do you use? Maybe update your lv2 headers may help.

[vssasks]

Yes, you understood correctly. I recompiled it with that additional line and installed it. It behaves the same way as the nonedited lv2. Do i need dev version of reaper too?

[vssasks]

Where should i get dev version of lv2?

[vssasks]

Sorry, misunderstood. You meant not fluida.lv2 but lv2-dev pack and it's 1.14-0~dfsg1-2

[brummer10]

Well, that's a real old version (2016). It may be that your issue with Fluida is related to that. Check out here: https://lv2plug.in/news.html You may download, build and install the latest version of lv2-dev and then rebuild Fluida against that. (Better remove the package from your distribution before you install your self build one) Other LV2 plugs you build by yourself may benefit from that as well.

[vssasks]

Ok, tried fluida recompiled with 1.18-lv2-dev and it did not help...

[vssasks]

Maybe you can make vst version?

[brummer10]

Strange. You could make a VST by yourself: https://github.com/x42/lv2vst uri for Fluida is https://github.com/brummer10/Fluida.lv2 so echo "https://github.com/brummer10/Fluida.lv2" >> ~/.vst/lv2vst/.whitelist after installing lv2vst should do it.

[vssasks]

Lv2vst helped, thanks! I can now load sf2s and get sounds. Only drawback that after reopening gui banks line becomes empty though sf is still playing i.e. i have to reload entire sf2 in order to load another instrument within same sf2. By the way where can i get ladspa to vst wrapper?
