Extended MPK249 MIDI Remote Script for Ableton 11

MPK249.py

# Extends the default MPK249 MIDI script for Ableton 11 Suite
# In this script the encoders effect the selection device instead of panning. Device selection follows track selection
# Directions:
# 1. Backup the original MPK249 directory:
#   Mac: /Applications/Ableton Live 11 Suite.app/Contents/App-Resources/MIDI Remote Scripts/MPK249
#   Windows: C:\ProgramData\Ableton\Live 11 Suite\Resources\MIDI Remote Scripts\MPK249
# 2. Delete the "MPK249.pyc" file in the original directory
# 3. Copy this file to the original directory and name it "MPK249.py"
# 4. Restart Ableton
