Hello community. First, have to note, that i'm not sure, what fluidsynth backend is best today, as first time i got it, was several years ago when i tried ubuntustudio (even simpler - just installed pro-media software to Ubuntu 7.04) and when ubuntu 10.04 released and even 12.04, i still suppose using of qsynth, since i don't now others with such full amount of settings. Now proposals. 1 - optional feature (i.e. with switch to disable it) to publish fluidsynth engines as dbus or other kind of services, exactly like what jack already has. If such option is enabled by default, then even when engine is loaded via linked library, as done in MuseScore, it still may be controlled by external gui like QSynth. Also, another example of such way is linuxsampler way (limited, because qsampler only allowes to change backend addess in settings, but hope it is to be fixed). 2 - only about gui at all, not only qsynth: i read one time somewhere, that fluidsynth supports microtonality (scale tuning), but only few months ago could try it in action, controlling manually standalone fluidsynth, started in terminal. It would be great to add in qsynth panel like in zyn/yoshimi for scale tuning. Also interested, is there some gui, where scale tuning is implemented (hard even to hope when even most featureful gui doesn't have it).
