[Feature request] sf3 support

[trebmuh]

Since SF3 is now supported within fluidsynth, it is now possible to support SF3 in software depending on fluidsynth which Carla is.

See LMMS/lmms#3895 and LMMS/lmms#3286 .

This needs new fluidsynth version.
I tried to update it before, but failed to build it.
To be done someday. Perhaps if you can point me to a good sf3-only file it will motivate me to support it faster :)

That is right that a lot of sf3 are available as well as sf2. This is because of its purpose I guess : "same as an sf2, but lighter weight because it's OGG and not WAV".

Promise, if I find one, I'll tell you!

(PS: I've got a working 1.1.8-1 version build for stretch which i giving me the ability to load SF3 in a few software)

I believe carla should support this now.
It will search for sf2 and sf3 files. The rest is up to fluidsynth to handle.
Please confirm.

Loads and make piano sounds for me, though I turned all the reverb/chorus dials up and it didn't sound different.

I see in the kxstudio builds at least, sf3 is not supported.
Need to update the static fluidsynth so it handles this.
It is a good idea to disable sf3 automatically.
I will close this issue, since carla itself can handle it now, it is something else that needs updating&check,

PS: regarding the chorus and reverb, these are soundfont specific, and also something that fluidsynth does internally. carla only tells fluidsynth to activate the parameters.

@falkTX I've rebuild a carla from GIT fcc1597 and the SF3 is working. Thanks!

I've spotted a small buggish thingy: while it reads the SF3, the "type column" is set to SF2. That's not a big deal but it did confuses me for a few minutes while I was searching for a SF3 with the help of the "type" column.

Please, let me know if you prefer a new issue to be open or if you're fine with being here.

Once again, thanks!

[falkTX]

yeah, not something I am going to "fix" right now.
SF2 is just the type of plugin/item in the list.
Naming it "SoundFont" might be an issue for stupid copyright reasons.

If it is something you really care about, open a new bug report for it.
But know in advance it is not something I will change in (very soon coming) 2.0 release.
