Comments on FluidSynth MIDI Synthesizer for Android
★★★★☆Bri Dono· Mar 11, 2023
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 sound font. If you test out a sound font, 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 sound fonts. Even with that, I still highly recommend it! - Jack

I give this app 10 stars but rating system only supports 5. This app plays all my sound fonts perfectly with filter and all midi controls etc. Working exactly as I set them up and with very low latency Wow!!!!! Only problem is no reverb. Fix that, and I will give you15 stars Reverb works fine and sounds very good now that I realized left channel reverb was cancelling right channel reverb. Setting the reverb width to zero fixed this and now all is well with the reverb.

Worked on a Casio WK 200 & Williams electronic keyboard, but I couldn't close the delay in the more than noticeable latency gap. Used it on an Alexis Q88 controller which had much less of a latency gap but worsening crackling in the audio, then the app stopped altogether transmitting through Bluetooth after I unplugged the usb B adapter end out. Will reinstall & see if I can get it going again tho, it had some promise being user-friendly up to a point. Used another device & Alexis Q88 controller

SFX -> Reverb -> Reset (button) does not only reset Reverb settings, but also deletes all assigned instruments and kills all sounds. Had to reinstall. No control over the sound volume is also quite disappointing. Otherwise -- synth, as in original library, works very similar to the PC version.

"Turn your device into a Fluid Synth synthesizer"... ONLY if you plug in a physical keyboard. There is no on-screen keyboard and no way to play midi files. This is just a fancy driver for a USB keyboard, kinda pointless really.

Was a good app for using a cheaper MIDI keyboard to play a cleaner sound front. New update has started to cause sound to crackle when playing, enough to the point that it's no longer usable. -Tested headphone, headphone aux cable, USB MIDI cable, and sound front file. -Tried disabling audio effects. -Tried changing in app volume.
