Action data structure actions:

bend	<time> <int>	# multiplied by poff - pitch offset
ccont	<time> <number> <value> # MIDI continiuous controller change
downtempo <int>		# delta meter change slower
dxparam	<number> <gindex> <hindex> <value> # dx7 sys.excl parameter
key	<note constant> # key signature
metro	<int>		# absolute meter change
notes: 
note 	<note> <time> <velocity # normal form
note	<note> <time>,<duration> <velocity> # duration form
patch	<int>		# MIDI patch change
poff	<constant>      # pitch offset - bend multiplier
rest	<time>
sig	<int> <int>	# time signature
tie	<time>
uptempo	<int>		# delta meter change faster
action  <action identifier> # action action (nested action datatype)
