Clone and transpose sequence, pattern or channel

[adamrenklint]

Makes a deep clone, executes callback, passing each note to be modified or rejected.

var newPattern = oldPattern.transpose(function (note) {
  if (note.key === "A2") note.key = "A3";
  if (note.key === "B1") return false;
});
var newChannel = newPattern.channel(1).transpose(...);
var newSequence = anySequence.transpose();

Is transpose an good term here, or is it confused by other meanings in music theory?
