Dangerously Set Inner Bernoulli Gate

This script is part of a series of Monome crow related scripts. It's provided as-is and for various reasons is not meant to work out of the box.

-- sentence --

The Dangerously Set Inner Bernoulli Gate takes two (mostly alternating) gate signals, evaluates them over each other and across time, to generate presumably interesting (and somewhat predictable) patterns.

Imagine four logical outputs asking questions to an MI Branches, every time it produces an A or B gate signal. Is output A being triggered, or B? Is it the 2nd time it plays? Is output 3 about to play? Did it play already?

-- grammar --

in order to generate these four sequences, each logical output is assigned a table of conditions that define whether or not an incoming gate signal should be forwarded to its corresponding physical output or not.

logicalOutputs = {
  { ifInput(1), ifStep(1, 7) },
  { ifInput(2), ifStep(3, 7) },
  { ifPrevOutput(2), ifNotOutput(1) },
  { ifPrevInput(1) }
}

These four logical outputs are tested everytime a gate comes in. More precisely, their own, custom set of conditions is scanned and ran independently. At any time, if any of these conditions is met (returns true), a pulse is forwarded to the corresponding output.

In other words, these logical outputs react to previous, incoming or future signals. Their response is somewhat predictable, but hard to guess in an forever changing, unenven distribution of signals. Everytime one of their condition is met, they forward a gate - or not, depending on which conjunction was set...

-- verbs --

In itself, a logical output is a set of primitive tests used to create complex, intricated conditions. Mixed, they become a logical mayhem. It sometimes results in interesting patterns.

List of these primitive tests:

ifInput(i:number[1-2]) Forwards input i gate state

ifNotInput(i) Inverts ifInput boolean result

ifPrevInput(i) Forwards past input i gate state

ifNotPrevInput(i) Inverts ifPrevInput boolean result

ifStep(n:number[1-SIGNATURE], ...) Creates a gate on a given step, inside the sequence. Takes a variable number of arguments (steps). SIGNATURE is a constant that defines the length of a sequence (defaults to 8).

ifNotStep(n, ...) Inverts ifStep boolean result

ifOutput(o:number[1-4]) Forwards a sibling gate state. If test is made on a previous sibling (eg. output 3 testing output 1), forwards its incoming gate state. If made on a following sibling, returns its previous gate state.

ifNotOutput(o) Inverts ifOutput boolean result

-- conjunctions --

Conjunctions are logical operators. They take the table of results of a logical output and ultimately decide to forward a pulse or do nothing.

-- OR -- OR cuts across it. If any of the tests returns true, returns true.

-- AND -- OR gets across it. If each of the tests returns true, returns true.

-- MOST-- MOST navigates through it. If most of the tests returns true, returns true.

Defaults to OR.

-- todo --

• Add methods inContiguousRange, inSequenceRange, ifRand, ifRand1
• Add a required property to test methods. it should set a logical output to false if condition is unmet
• Make the whole script actually work with Crow..
• Provide examples of interesting logical outputs
