-- mode sets rhythmic relations:
--  cycle:  rhythmic undulation to the envelope level
--		The rhythm is generated similarly to transient, 
--			however the variation is applied continuously
--			(rather than in single steps of beats).
--		Applying RUN voltage emphasizes every 2nd then 3rd then 4th event, 
--			however all the in-between beats are available too. 
--		Subtle CV shifts allow for a variation of groove 
--			with nothing but volume manipulation.
--		Negative RUN levels emphasize every fraction of a beat.
--		Works extra well with quantize active.


--  sustain:  	
--		The first envelope is full volume and each one thereafter 
--			will decrease in level. 

--		By adding a RUN voltage the rate of decay can be modified.

--		TIME & INTONE set a base envelope rate, divisions sets the 
--			rhythm of notes, and RUN sets the amplitude cycle 
--			relative to repeats.

--  transient: 	
--		Each output has the same level
--		RUN voltages will introduce a rhythmic variation every n repeats. 

-- The TIME & INTONE controls maintain their standard free-running influence, 
--		speeding up and slowing down envelopes, 
--		while the rhythms are controlled remotely.
-- ii.jf.play_note( divs, repeats ) 
-- 		Play a sequence, dynamically allocated to a channel
-- ii.jf.play_voice( channel, divs, repeats ) 
-- 		Play a sequence on a specific *channel*
--		min divs is 1
--		sending repeats a negative number has it repeat infinitely
-- ii.jf.tick( divs ) 
-- 		Clock *Geode* with a stream of ticks at *divs* per measure
-- ii.jf.tick( bpm ) 
-- 		Set timebase for *Geode* with a static *bpm*
-- ii.jf.quantize( divisions ) 
-- 		Quantize *Geode* events to *divisions* of the timebase
