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 this app! 💖 Only thing else I could ask for would be able to save my favorites in a specific section of the app & a midi map feature! Solid work! Update: I keep running into a glitch where no audio is output & I have to reinstall the app everytime to fix it

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.
