ok i will try
MIDI is data, that's all it is
it is the handler in all V-Accordions between your fingers on the keyboard
and the sound generation hardware
sending it "out" to another device is simply "CC" ing it like you do
an eMail you want to send to two or more people
the software that is used to accept this type of data on a computer
or a dedicated device is called a sequencer
a sequencer is to MIDI data what a Word Processor is to a modern day paperback Writer
a word processor keeps the alphabet in the order you need for the specific story
you are writing, keeps the spacing, the font, the capitals, the underlines, the italics
a Sequencer starts with the beat, keeps a tempo so the notes are in measured order,
and keeps (each) the time the note begins, length, how and when it ends, and intensity during
if you send the data back into the V-Accordion and use it's sound generator,
the result should sound exactly the same.
since it is data, it is then rather infinitely able to be manipulated, as well as being
played back infinite times with no change or loss
data is data
the basic MIDI sends information on up to 16 channels at a time, with
accordions typically using track 1 for melody, 2 for Chords 3 for Bass
some use 2 for bass 3 for chords..
on the computer screen there are usually a variety of visual representations
you can use to view and work with the data including "Sheet Music"
