I have a digital Yahama piano with a MIDI out port. I would like to record a MIDI file by playing the piano, connecting the piano with an Android (or Raspberry Pi) device. Once the MIDI file is made, I can edit it on a more powerful device.
My biggest question is what's the best way to connect the piano? The most simple solution looks like a MIDI tot (micro)USB cable like this one, but these cables get often a bad review.
Anyone has any experience with this?
