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

[H P Ladds]

Hey Peter,

Thanks again for all your help. The solution to my problem was at the other end of my nose... in your script.

I now see that your script is probably called from /home/pi/.profile.

In short, your advice was concise and spot on. It just took me a bit of study to realize it.

Thanks again,

Preston

Hi Preston,

The fluidsynth command line options in the script have -is. i says no-shell, s says run as a server. Then the terminal session started automatically at boot starts it up. It seems to work reliably enough for me, although there is a delay (5 sec? in the script that I might lengthen as the large soundfont file that I am using seems to take a bit more digestion.

There is probably a smart way to query status from fluidsynth (are you ready yet?) but I don’t know it.

Hi Peter,

Man! I had a miserable experience getting fluidsynth to run at boot. I tried everything: editing the rc.local,.bashrc, init.d,even tried my hand at the new system.

Somewhere I stumbled upon the "-- no-shell" and the "-- service" options and one of these (I don't know which just yet) did the trick for me.

Thanks again for the script. Does it run successfully at boot time? I don't understand how it does this?

Cheers,

Preston

Hi Preston,

What I actually have is an organ with a Teensy 3.2 running Arduino code reading the keystrokes and producing a MIDI stream to a USB port. This USB then connects into the RPi where fluidsynth processes the MIDI into an audio output. So logically I imagine Piano Booster also produces MIDI which you want to run into fluidsynth in a similar way. You would probably run the amidi -i and amidi -o commands as detailed by Ted, and change the script to get the right port name for the PB output stream.

Hi Peter,

Thanks so much for the script. Good to know that you got it to work. One line in the script had me wondering.

"echo Arduino input port: $myownport" Did this script also work on the RPi?

My next step is to optimize the "machine" to the task of making sound.  Ted Felix MIDI should be some help.

Cheers,

Preston

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.
