Implementation Reference

• AbletonMCP_Remote_Script/__init__.py:457-475 (handler)

  The actual Ableton Live API implementation for creating a clip in a specific track/slot.

  def _create_clip(self, track_index, clip_index, length):
      """Create a new MIDI clip in the specified track and clip slot"""
      try:
          if track_index < 0 or track_index >= len(self._song.tracks):
              raise IndexError("Track index out of range")
          
          track = self._song.tracks[track_index]
          
          if clip_index < 0 or clip_index >= len(track.clip_slots):
              raise IndexError("Clip index out of range")
          
          clip_slot = track.clip_slots[clip_index]
          
          # Check if the clip slot already has a clip
          if clip_slot.has_clip:
              raise Exception("Clip slot already has a clip")
          
          # Create the clip
          clip_slot.create_clip(length)

• MCP_Server/server.py:282-300 (handler)

  The MCP tool handler for create_clip, which invokes the command in the Remote Script.
