Re: [fluid-dev] Systemd, Raspberry Pi and Fluidsynth

[Peter Hanlon]

I don’t claim to be an expert, but amended a script to my requirements.

I finished with a script called ‘fluid’ which I installed in /usr/local/bin.

I also established a user called synth in the ‘audio’ group, to help with 
latency, and added a couple of lines to the end of /home/pi/.profile, 
consisting of first line 'sudo su synth’, and second line ‘fluid start’.

Google Ted Felix MIDI for better info.

In my case, I also needed to hold off on supplying MIDI until fluid synth was 
ready for it. You could probably extend the script to start the other 
application.
