# Repetition.sc

A set of tools to build a `Stream` of Events`.

Current version: `0.3`

## Installation

Simply open a new document on your SC IDE and type:

    Quarks.install("https://github.com/lvm/Repetition.sc");

This should print something like this in the Post window:

    Installing Repetition

    Installing PercSymbol

    PercSymbol installed

    Installing FluidSynth

    FluidSynth installed

    Installing Bjorklund

    Bjorklund installed

    Repetition installed

    -> Quark: Repetition[0.1]

## Getting started

Once Repetition is properly installed and everything working correctly, type the following:

    (

    p = ProxySpace.push(s);

    p.makeTempoClock;

    p.clock.tempo = 2;

    p.quant = 4

    ;

    r = Repetition(p);

    m = r.initMIDI("Midi Through", "Midi Through Port-0");

    r.midiEventTypes;

    )

So, pretty much that's it.

## The *language*

The parser recognizes the following _symbols_:

* Parallel: `a|b`, plays symbols simultaneously. Kind of a Chord.

* Groups: `a+b`, plays symbols sharing the duration. If the duration is 1, each will have a duration of 1/2.

* Accent: `a@`, sums a quarter of the original amplitude to it. That is: amplitude/4.

* Shift octave up: `a'`, Current Octave +1.

* Shift octave down: `a,`, Current Octave -1.

* Repeat once: `a!`, Repeats the symbol once.

* Repeat N times: `a*N` (`N -> Int`), Repeats symbols `N` times.

All of them are "chainable". For example, a Pattern (ab)using every option available:

```

"a*3 b@+c' d@!, e+f".asRepetitionStream.nextNRP(23);

-> [ ( 'dur': 0.14285714285714, 'symbol': a, 'shift': 0, 'midinote': 9,

  'typeof': note, 'accent': 0 ), ( 'dur': 0.14285714285714, 'symbol': a, 'shift': 0, 'midinote': 9,

  'typeof': note, 'accent': 0 ), ( 'dur': 0.14285714285714, 'symbol': a, 'shift': 0, 'midinote': 9,

  'typeof': note, 'accent': 0 ), ( 'dur': 0.071428571428571, 'symbol': b@, 'shift': 0, 'midinote': 11,

  'typeof': note, 'accent': 0.25 ), ( 'dur': 0.071428571428571, 'symbol': c', 'shift': 1, 'midinote': 0,

  'typeof': note, 'accent': 0 ...etc...

```

```

~x[0] =  "c a f e".pbind(\instrument, \default, \amp, 0.5);

~x.play;

```
