## Installing
|
|
|
|
You need to install SuperCollider and the Dr Racket package.
|
|
|
|
### 1. Installing SuperCollider
|
|
|
|
Go to https://supercollider.github.io/download.html and download the latest version (3.6.6 as of the time of writing.)
|
|
|
|
Then follow these instructions per operating system.
|
|
|
|
#### Linux
|
|
|
|
- install jack
|
|
|
|
#### Windows
|
|
|
|
#### Mac OS X
|
|
|
|
|
|
### 2. Installing oregano
|
|
|
|
This can be installed in two different ways:
|
|
- Either through the command line: `raco pkg install rsc3`
|
|
|
|
- Or through DrRacket: TODO
|
|
|
|
|
|
|
|
## Concepts
|
|
|
|
You can play notes from instruments on specific tracks.
|
|
|
|
The purpose of playing notes on different tracks is we can have different filters on different tracks. For example, the melody track can have a low pass filter, and and the drums track could have a delay filter.
|
|
|
|
|
|
- Instrument: This is equivalent to choosing what the note sounds like. There are default instruments (saw wave, piano, etc.) and you can also define your own using samples.
|
|
- Note: specifies a key from an instrument, and can be played on a track
|
|
- Track:
|
|
- Filters: can be added to a track. The order in which they are added matters.
|
|
|
|
|
|
## Example
|
|
|
|
### 1. Creating an instrument
|
|
|
|
You can either use a preset instrument or define your own instrument
|
|
|
|
;; this uses the piano preset
|
|
(define my-piano (make-instrument 'piano))
|
|
|
|
;; create a custom instrument
|
|
;; can use oscilators and envelopes
|
|
(define my-instrument (make-instrument ... TODO))
|
|
|
|
;; add envelope to instrument
|
|
|
|
### 2. Playing a note
|
|
|
|
Now that we have an instrument, we can use it to play notes on a specific track.
|
|
|
|
;; this plays the key C#, octave 3 on track 2.
|
|
(note-on my-piano C#3 track2)
|
|
|
|
;; to stop playing
|
|
(note-off my-piano C#3 track2)
|
|
|
|
;; TODO - find a way to turn off a note, or make a note play for a specific time
|
|
|
|
|
|
TODO:
|
|
- use an instrument to play a note on a track.
|
|
- add filters to a track
|
|
|
|
