Help needed to include FluidSynth sound library in Android app.

I'm developing an Android app that needs to play musical notes of different instruments, using either MIDI or something similar.

I will do everything else in the app, but I need help in embedding a synth in the app, which will do the actual playing of the notes.

After some research I figured that the FluidSynth open source library may be a good way to achieve that. Here are some references:

I also found several Android apps on Google Play Store which use FluidSynth to play MIDI files or individual MIDI notes (e.g. when the user presses a key on a keyboard on the screen). For example LiveMIDI and "MIDI Voyager" are two Android apps that use FluidSynth.

Now, for my app, I need to do something similar. The basic operations that I need to do are:

1. Load one or more SF2 files

2. Have multiple channels playing different instrument

3. Perform these basic operations: Play note, silence note, set channel volume, set channel instrument, change channel pitch (pitch bend).

4. FluidSynth includes some optional effects such as reverb, echo, etc. I'd like to be able to add these effects as well. (But it is not absolutely necessary)

I don't care if I have to use standard MIDI messages to perform the above operations, or if there are different methods to call to play the notes directly from the synth. The important thing is that I should be able to play musical notes and do the above basic operations, one way or the other.

In fact, if you know a different way of achieving that result, without using FluidSynth, I am also interested.

I'm looking forward to hearing from you!

All the best
