Is MIDI with GPIO serial still working as of today? #49

See https://www.samplerbox.org/article/midiinwithrpi point 3.

Needs to be double-checked if it still works nowadays, with new kernels.

There are 3 places to check:

• https://github.com/josephernest/SamplerBox/blob/master/isoimage/root/boot/config.txt
• https://github.com/josephernest/SamplerBox/blob/master/isoimage/root/boot/cmdline.txt

• SamplerBox/samplerbox.py

  Line 387 in ea16c5f

  ser = serial.Serial('/dev/ttyAMA0', baudrate=31250)

Then we have to connect a real hardware synthesizer (e.g. Roland or Yamaha), and see if it still works.
