I am not a musician (I can play the piano with one hand, but lack the coordination to bring the other hand into play at the same time), nor can I read music. My interest is in the use of a PC and MIDI interface to allow music played on a keyboard to be stored and edited on a computer, then played back through the sound synthesis portion of the keyboard again. Unfortunately, my inability to play the keyboard or read music is further handicapped by the lack of suitable equipment (or funds for such!). My PC is equipped with a 16-bit SoundBlaster card, and I have MIDI player/editor software, but no MIDI interface widget, and my keyboard is not MIDI compatible, anyway. So I currently content myself with examining MIDI files that ather people have created, and playing with them - changing instruments, cutting and pasting, etc., while playing them back through the SB card.
Using my editor, I did once actually enter a short piece, note-by-painful-note, onto the stave, and then added a rhythm line, and a base line. But for a piece that lasts only 20 seconds or so, this was an incredibly arduous task, that I wouldn't recommend to anyone, if they have a keyboard to use instead.
