Ratings and reviews

My experience is a bit buggy - Neither the Reverb nor Chorus tabs seem to have an effect, whether or not they are active, which is quite disappointing. Additionally, once I've quit out of the software, it still seems to be interpretting MIDI input on my phone, layering the soundfonts over other apps I've switched over to.

Love the responsiveness (no latency) between keyboard and output. The app recognizes all the main midi commands. There's still plenty of SF2 sounds out there to take advantage of. The only issue is that I have been unable to find a way to delete any individual soundfont. If you test out a soundfont, and then don't like it, I can't delete it. I have to go to the apps data and delete that way, but that deletes all soundfonts. Even with that, I still highly recommend it! - Jack

Works incredibly well with my controller app BeatScratch! I plan to link to it from within the app. My one complaint: after switching SoundFonts, the synthesizer starts going kinda glitchy and restarting all the time. If I go into the Android app info for the settings, "Force stop" it, and then try again, FluidSynth plays everything beautifully. But something in switching the fonts is broken unless you do this.
