The
accordion has MIDI system installed. The connector is next to the
microphones pick up (see the picture below). I will try to find a
power supply that will work with the instrument since it was not
available at the time I acquired the accordion. Consider this
electronics a bonus where I find the power supply or not. If the new
owner prefers to have the MIDI removed this could be done in a clean
professional way without affecting the performance or appearance of
the instrument.
