# cnoidal

*Cnoidal* is a Haskell library for representing, transforming, and live coding music.

The library is based on the notion of *temporal media*, a data type that represents a collection of time intervals tagged with values. It supports various functor instances, like Applicative Functor, which are highly useful for live coding.

The name is inspired by the [cnoidal waveform][cnoidal], a nondispersive shape that water waves can take.

## Documentation

### Talk at FARM 2019

A first version of the library was presented at the [FARM 2019][farm2019] workshop [at the ICFP 2019 in Berlin][berlin]. This presentation focuses on the *temporal media* data type, which represents music as a collection of time intervals tagged with values. It supports an Applicative Functor instance which is highly useful for live coding. However, a lawful Monad instance can only be defined for some variants of the data type. After introducing these functor instance, I gave a hands-on demonstration and live coded some music.

* Slides: [slides-functors-and-music.pdf [pdf]](doc/farm2019/slides-functors-and-music.pdf)
* Performance: One of a kind, never to be repeated. But here is a very similar worksheet that I created in preparation for the performance: [not-the-performance.hhs [HyperHaskell worksheet]](doc/farm2019/not-the-performance.hhs)

### Audio output

By itself, the `Cnoidal.Player` module only allows you to output MIDI messages. You will need a MIDI instrument to actually hear sound. However, you can find many software instruments on the internet. On the open source side, you can use

* [fluidsynth][] — a synthesizer that uses Soundfonts.
  * [csound-expression][] — a Haskell library that wraps the [Csound][] language.

On the commercial side, you can use most digital audio workstations (DAW) or a performance-oriented application like [MainStage][].
