Thanks, all!
Tom, you were right, the arguments in my call were not getting used for
some reason. I remedied this by taking out the "shell=True" from the call
to "subprocess.check_call(fluidsynth_command)". Now the wav file can render!
Now I'm onto trying to get the subsequent conversion from wav t

For some reason fluidsynth starts the OSS audio driver rather than the file
renderer. As if you were calling
fluidsynth_exec/fluidsynth -ni tmp_sf2_file_name tmp_mid_file_name
Make sure your python script doesn't omitt the last two flags. Note that t
Hi Justin,
You don't need a proper audio driver for fast rendering. So simply use "-a
file" to select the file renderer.
With the other problem I'm afraid I can't really help, I don't have any
experience with this Amazon serverless computing black magic...
Cheers,
Marcus
Thanks, great advice! I'm definitely getting further, but still facing
issues.
I created a new virtual ec2 instance locally on my mac, and installed all
the dependencies with yum, not LinuxBrew (dependencies needed were
libsndfile-devel and glib2-devel). I've generated a fluidsynth binary and
I'm

Cool, thanks! I've now set up a virtual EC2 instance locally on my mac, and
complied fluidsynth, as you've suggested. I'm still having execution
issues, though when I try to call the subprocess to run fluidsynth on the
lambda as a subprocess of my python lambda function:
-ni: fluidsynth_exec/fluid
Hi!
The easiest might be to skip cross compiling and build it natively. So
either on an AWS instance, or on a virtual machine on your Mac. On the VM,
just install the built-essential libsndfile-dev, libglib-dev and cmake
packages (or whatever they are called on the distro you are using), build
it
Thanks for the quick reply! Installing the dependencies via homebrew fixed
my issue, and fluidsynth can now do the conversion for me locally!
However, I'm facing another issue now, which probably comes from the fact
that I compiled the code on my mac, and I'm trying to run it on AWS lambda
(which I
Hi Justin,
you probably compiled Fluidsynth without libsndfile support, so the
resulting audio is a raw 16-bit signed dual-channel float audio file (so
not a .wav file with proper headers). You can either convert this raw file
to wav using some tool, or install libsndfile-dev (or whatever it's cal
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.
