Structures defining musical dynamics

dynamics's Issues

Implement DynamicInterpolation

AKA "Hairpin", but richer

struct DynamicInterpolation {
    let startDynamic: Dynamic
    let stopDynamic: Dynamic
    // curve ? exponent ? etc ?
}

Conform DynamicAggregate to StringLiteralConvertible

Initialize a DynamicAggregate:

let dynamicAggregate = "offffpppp" | etc.

Conform Dynamic to StringLiteralConvertible

Initialize a Dynamic:

let dynamic = "fff" | "ppp" | "mp" | "mf"

Implement Dynamic

struct Dynamic {
    // in init, ensure proper order, allowed components, make throw
    init(string: String) { } // "fff", "ppp", "mp", "sfz"
}

extension Dynamic: Comparable { }

func == (...) -> Bool
func < (...) -> Bool

Implement DynamicSequence

struct DynamicSequence {
    let dynamicAggregates: [DynamicAggregate]
    init() { }
}

extension DynamicSequence: SequenceType { 
    ...
}

Implement DynamicAggregate

struct DynamicAggregate {
    let dynamics: [Dynamic]
    let startDynamic: Dynamic // computed (.first!)
    let stopDynamic: Dynamic // computed (.last!)
    init(string: String) { } // "fff", "sfffp", "smfz", "offfffpp"
}

extension DynamicAggregate: SequenceType { 
    ...
}
