copied!<p>Think of MIDI as like defining piano keys. Codes and keys are one-to-one. This is unlike a guitar or violin, where the same tone can be played in multiple places.</p> <p>If you want to represent the greater freedom you have on a guitar in some data format, you'll have to find or invent a different format. MIDI won't encode what you want.</p> <p>However, there's an indirect way you might go about this, and it has to do with developing heuristics as to where to play a note given a sliding window of notes that came before. A given note may be easier on one string or another depending on what you've just played, and you can calculate that given a model of the hand and where fingers will have been. Based on this, you can convert MIDI to guitar in a way that makes the MIDI easiest to play. If you have a piece of guitar music that follows these rules already, then you can encode it in MIDI and then decode it later.</p> <p>But perhaps your question is more basic. Yes, you can map a MIDI note to a guitar. The naive method is to make a mapping of each note playable on the guitar, and you decide between equivalent alternatives by picking the one closest to the nut. This would be an easy one-to-one mapping but wouldn't necessarily be the easiest to play.</p> <p>If you REALLY want to do it right, you'll do a careful analysis of the music to decide the optimal hand position and where the hand position should change, and then you'd associate MIDI notes with frets and strings based on what's easiest to reach based on the hand position. The optimal solution is probably NP-complete or worse, do you'd probably want to develop an approximate solution based on some rules about how often and how far you can change hand position.</p>
