[fluid-dev] Trouble building/using fluidsynth

[Justin]

Hello, I'm trying to compile a fluidsynth binary. For my application, I need a way to convert from midi to mp3 on an AWS lambda, and I thought that using fluidsynth would be the best way. These are the steps I took:

1. Clone fluidsynth from here: https://github.com/FluidSynth/fluidsynth
   
2. Created build directory and ran 'cmake ..' from build directory
3. Ran 'make fluidsynth' from build directory. This seemed to create a binary file called 'fluidsynth' in build/src directory
4. Downloaded a sound font file from https://github.com/urish/cinto/blob/master/media/FluidR3%20GM.sf2 (renamed to sf.sf2 for convenience

Running the binary gave the following output:

> fluidsynth -ni sf.sf2 some_midi.mid -F output.wav -r 44100

FluidSynth runtime version 2.0.2

Rendering audio to file 'output.wav'..

However, when I tried to play the output.wav file that was generated, it just gave a short loud click/pop.

I'm not sure what I'm doing wrong. Could someone give me some advice for how to figure out how to get this working? Or is there a better way for me to get fluidsynth to work on AWS lambda?

Thanks!

Justin
