What’s the contents of your rc.local? It might be simpler to launch it as Pure Data module via patchbox, place your PD file in /usr/local/puredata-patches/<your_subfolder>/main.pd

my rc.local #!/bin/sh #temp sudo modprobe snd-virmidi index=5 midi_devs=1 #temp sleep 10 #temp amidiminder -f /etc/amidiminder.rules -C #pd -noaudio -midiindev 1,2,3,4 -midioutdev 1,2,3,4 -alsamidi -nogui -path ~/Documents/Pd/externals/else -lib else -nrt -verbose -d 4 /home/pd/pi4midi.pd & …

it just does not want to work when from rc.local all good from command line but not from rc.local i stick with pi os lite,for now maybe i come back to this later on cause would be nice to have patchbox since it is audio dedicated distro thx!
