# Fader = 8
# ---------------------
# Misc. Info
# Knobs and buttons are all channel 0
# Fader is channel 8
# Button presses (including knobs) are notes at velocity 127
# Knob turns counter-clockwise are a value of 64 + n,
# where n is a small number reflecting the amount it was turned within the last polling period
# Knob turns clockwise are a value of 0 + n,
# where n is a small number reflecting the amount it was turned within the last polling period
# Default column apps
# When you (re)start the script, it looks for the pids of the binaries specified for each column and sets the pid for each column
# These are overridden for the session by the bind_application function
