randomly updating ableton live device parameter using python

#------------------------------------------------------------------------
# Basic random test based on some example from
# https://github.com/ideoforms/pylive
#
# Every beat randomly pick a parameter from device[0] from track[0] 
# and randomize it's value
#------------------------------------------------------------------------

import live, random

#------------------------------------------------------------------------
# Scan the set's contents and set its tempo to 110bpm.
#------------------------------------------------------------------------
set = live.Set()

# we probably don't need this line here.
# anyway it's fun to have it.
set.scan(scan_clip_names = True, scan_devices = True)

#------------------------------------------------------------------------
# Each Set contains a list of Track objects.
#------------------------------------------------------------------------
track = set.tracks[0]
print "track name %s" % track.name

clip = track.clips[0]
print "clip name %s, length %d beats" % (clip.name, clip.length)

#------------------------------------------------------------------------
# Now let's modulate the parameters of a Device object.
#------------------------------------------------------------------------
device = track.devices[0]
print "device -> %s" % device.name

while True:

  parameter = random.choice(device.parameters)
  value     = random.uniform(parameter.minimum, parameter.maximum)

  parameter.value = value

  print "setting %s to: %.4f" % ( parameter.name, value )

  set.wait_for_next_beat()
