FluidSynth MIDI Synthesizer Customer Insights

1. Edit: Was able to accomplish this by setting the knobs and faders to certain MIDI CC values on the controller."Turn your device into a FluidSynth synthesizer"... ONLY if you plug in a physical keyboard.

2. I do not see ads int he app currently (5/2021) and am not sure what the puchase unlocks.The app is great I am using it most of the time, it would be great if you add a Individual volume control for channels.I loaded this on my new Samsung Galaxy Tab A, and it worked with my AKAI EWI-USB, so I bought the premium version.

3. I'm looking forward to trying out the dozens of SF1 and SF2 files I created back in the day using Vienna Soundfont Studio & my AWE64 SB card... (Those were the days 😏) I'm still figuring out the small bit and I'm hoping I can save banks with their effect settings in tact.

4. From what I see, it does nothing except perfectly render your MIDI input via the included SoundFont, or a SoundFont (SF2) that you find and load.

5. A feature that I would love to see is the ability to link the Reverb, Chorus, and Gain parameters to the knobs and faders on my controller, I would pay the premium for at least that feature, if it is possible.

6. But something in switching the fonts is broken unless you do this.Keystation Mini 32: 1)Easily recognizes & connects 2)Some internal sounds acceptable, others are a little thin.

7. That's all there is to it, assuming your phone recognizes your MIDI keyboard.

8. There is no on-screen keyboard and no way to play midi files.

9. The only issue is that I have been unable to find a way to delete any individual soundfont.

10. My one complaint: after switching SoundFonts, the synthesizer starts going kinda glitchy and restarting all the time.

11. 4)This demand tells me that sticking with my pc is only practical although on a basic level the software does work.
