Dear Ben,
Thank you for your email and sorry about the delayed response.
I tried using the syntax you've used, but the problem persists. Everything works except the loading of the configuration file. The funny thing is, if I run the same script manually after boot, the config file loads fine! I tried it with and without sudo, but it just doesn't work.
I have a feeling this has something to do with the way the script is executed. I'm running it by putting its path in /etc/rc.local
Do you think that's where the problem could be?
Incidentally, the config file I'm using is a tuning file which I'm using to load a specific tuning into fluidsynth. I'm attaching both the script and the config file for your reference.
To answer your question, I'm using a korg microkey keyboard controller and a HiFiberry DAC+. I looked at your EWI-Pi project and it looks awesome! This is actually similar to what I'm trying to do. I'm trying to build a similar self-contained instrument capable of playing certain custom tunings. I'm using a keyboard instead of an EWI, of course.
Thanks for your help!
