Linux example code in C for ALSA MIDI out. Could not find any working short example, so I made this.

sudo apt-get install libasound2-dev

gcc -o alsa_midi_out alsa_midi_out.c -lasound

./alsa_midi_out

• Start program in terminal it will give a MIDI out unit to connect to a soundsource with MIDI-in.
• Connect it together with a program like aconnectgui
• When ready press return for the first note.
• Continue to press return untill all 7 notes are played,
• then program exits automatically.
