## Basic test with ALSA and Fluidsynth
aplay -l # List soundcards, take note of 'card {cardnum}' for USB audio interface
fluidsynth -is -o audio.alsa.device=hw:{cardnum} --audio-driver=alsa --gain 3 /usr/share/sounds/sf2/FluidR3_GM.sf2 & # Start fluidsynth
acconect -o # Look for Fluidsynth's client number {out}
acconect -i # Look for MIDI keyboard's client number {in}
aconnect {in} {out} # Connect input to output
aseqdump -p {in} # For debugging (should print message events to console)
## Find and kill fluidsynth
ps -a
kill {PID}For example, boot read-only mode with options:
