• src/reaper_mcp/reaper_adapter.py:227-240 (handler)

  The actual implementation in `ReaperAdapter` that calls the bridge client to create a MIDI item.

  def create_midi_item(
      self,
      track_index: int,
      start: float,
      end: float,
      notes: list[dict[str, Any]] | None = None,
  ) -> dict[str, Any]:
      return self._client.call(
          "create_midi_item",
          track_index=track_index,
          start=start,
          end=end,
          notes=notes or [],
      )
