As a means of learning Erlang, I have created a module that implements **gen\_statem** controlling access to a port opened for a [FluidSynth](https://www.fluidsynth.org) command.

If anyone would be so kind as to review the module and give any feedback, such as things I am doing the hard way, etc., it would be much appreciated.

I have written up a Gist here:

[https://gist.github.com/EarthCitizen/b24efc85e815d77bd81ae51f677ede8f](https://gist.github.com/EarthCitizen/b24efc85e815d77bd81ae51f677ede8f)

Comment here or in the Gist. Either way is OK for me.

Thank you!
