--- An exploration of Just Friends' Geode

-- from maps with trent: https://www.youtube.com/watch?v=fMzM4omsIg8&ab_channel=Trent

-- 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
